+
+usRequestedPWMFreqInHz:           When it's set to 0x0 by SBIOS: the LCD BackLight is not controlled by GPU(SW). 
+                                  Any attempt to change BL using VBIOS function or enable VariBri from PP table is not effective since ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==0;
+                                  
+                                  When it's set to a non-zero frequency, the BackLight is controlled by GPU (SW) in one of two ways below:
+                                  1. SW uses the GPU BL PWM output to control the BL, in chis case, this non-zero frequency determines what freq GPU should use;
+                                  VBIOS will set up proper PWM frequency and ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1,as the result,
+                                  Changing BL using VBIOS function is functional in both driver and non-driver present environment; 
+                                  and enabling VariBri under the driver environment from PP table is optional.
+
+                                  2. SW uses other means to control BL (like DPCD),this non-zero frequency serves as a flag only indicating
+                                  that BL control from GPU is expected.
+                                  VBIOS will NOT set up PWM frequency but make ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1
+                                  Changing BL using VBIOS function could be functional in both driver and non-driver present environment,but
+                                  it's per platform 
+                                  and enabling VariBri under the driver environment from PP table is optional.

+	depends on BLK_DEV_DM
+	---help---
+	  This device-mapper target creates a device that supports an arbitrary
+	  mapping of fixed-size regions of I/O across a fixed set of paths.
+	  The path used for any specific region can be switched dynamically
+	  by sending the target a message.
+
+	  To compile this code as a module, choose M here: the module will
+	  be called dm-switch.
+
+	  If unsure, say N.

+ * Bootloader Messaging Interface (BMI)
+ *
+ * BMI is a very simple messaging interface used during initialization
+ * to read memory, write memory, execute code, and to define an
+ * application entry PC.
+ *
+ * It is used to download an application to QCA988x, to provide
+ * patches to code that is already resident on QCA988x, and generally
+ * to examine and modify state.  The Host has an opportunity to use
+ * BMI only once during bootup.  Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0.   BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR8K Counter #4.  As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

+/*
+ * A single CopyEngine (CE) comprises two "rings":
+ *   a source ring
+ *   a destination ring
+ *
+ * Each ring consists of a number of descriptors which specify
+ * an address, length, and meta-data.
+ *
+ * Typically, one side of the PCIe interconnect (Host or Target)
+ * controls one ring and the other side controls the other ring.
+ * The source side chooses when to initiate a transfer and it
+ * chooses what to send (buffer address, length). The destination
+ * side keeps a supply of "anonymous receive buffers" available and
+ * it handles incoming data as it arrives (when the destination
+ * recieves an interrupt).
+ *
+ * The sender may send a simple buffer (address/length) or it may
+ * send a small list of buffers.  When a small list is sent, hardware
+ * "gathers" these and they end up in a single destination buffer
+ * with a single interrupt.
+ *
+ * There are several "contexts" managed by this layer -- more, it
+ * may seem -- than should be needed. These are provided mainly for
+ * maximum flexibility and especially to facilitate a simpler HIF
+ * implementation. There are per-CopyEngine recv, send, and watermark
+ * contexts. These are supplied by the caller when a recv, send,
+ * or watermark handler is established and they are echoed back to
+ * the caller when the respective callbacks are invoked. There is
+ * also a per-transfer context supplied by the caller when a buffer
+ * (or sendlist) is sent and when a buffer is enqueued for recv.
+ * These per-transfer contexts are echoed back to the caller when
+ * the buffer is sent/received.

+ *
+ * Yet there is some complexity with direct accesses because the
+ * Target's power state is not known a priori. The Host must issue
+ * special PCIe reads/writes in order to explicitly wake the Target
+ * and to verify that it is awake and will remain awake.
+ *
+ * Usage:
+ *
+ *   Use ath10k_pci_read32 and ath10k_pci_write32 to access Target space.
+ *   These calls must be bracketed by ath10k_pci_wake and
+ *   ath10k_pci_sleep.  A single BEGIN/END pair is adequate for
+ *   multiple READ/WRITE operations.
+ *
+ *   Use ath10k_pci_wake to put the Target in a state in
+ *   which it is legal for the Host to directly access it. This
+ *   may involve waking the Target from a low power state, which
+ *   may take up to 2Ms!
+ *
+ *   Use ath10k_pci_sleep to tell the Target that as far as
+ *   this code path is concerned, it no longer needs to remain
+ *   directly accessible.  BEGIN/END is under a reference counter;

+ * This file specifies the WMI interface for the Unified Software
+ * Architecture.
+ *
+ * It includes definitions of all the commands and events. Commands are
+ * messages from the host to the target. Events and Replies are messages
+ * from the target to the host.
+ *
+ * Ownership of correctness in regards to WMI commands belongs to the host
+ * driver and the target is not required to validate parameters for value,
+ * proper range, or any other checking.
+ *
+ * Guidelines for extending this interface are below.
+ *
+ * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
+ *
+ * 2. Use ONLY u32 type for defining member variables within WMI
+ *    command/event structures. Do not use u8, u16, bool or
+ *    enum types within these structures.
+ *
+ * 3. DO NOT define bit fields within structures. Implement bit fields
+ *    using masks if necessary. Do not use the programming language's bit
+ *    field definition.
+ *
+ * 4. Define macros for encode/decode of u8, u16 fields within
+ *    the u32 variables. Use these macros for set/get of these fields.
+ *    Try to use this to optimize the structure without bloating it with
+ *    u32 variables for every lower sized field.
+ *
+ * 5. Do not use PACK/UNPACK attributes for the structures as each member
+ *    variable is already 4-byte aligned by virtue of being a u32
+ *    type.
+ *
+ * 6. Comment each parameter part of the WMI command/event structure by
+ *    using the 2 stars at the begining of C comment instead of one star to
+ *    enable HTML document generation using Doxygen.

+# lpfc_max_luns: maximum allowed LUN ID. This is the highest LUN ID that

+#    used; and is also the highest LUN ID allowed when the SCSI midlayer
+#    parses REPORT_LUN responses. The lpfc driver has no LUN count or
+#    LUN ID limit, but the SCSI midlayer requires this field for the uses
+#    above. The lpfc driver limits the default value to 255 for two reasons.
+#    As it bounds the sequential scan loop, scanning for thousands of luns
+#    on a target can take minutes of wall clock time.  Additionally,
+#    there are FC targets, such as JBODs, that only recognize 8-bits of
+#    LUN ID. When they receive a value greater than 8 bits, they chop off
+#    the high order bits. In other words, they see LUN IDs 0, 256, 512,
+#    and so on all as LUN ID 0. This causes the linux kernel, which sees
+#    valid responses at each of the LUN IDs, to believe there are multiple
+#    devices present, when in fact, there is only 1.
+#    A customer that is aware of their target behaviors, and the results as
+#    indicated above, is welcome to increase the lpfc_max_luns value.

- *      is given to CsrSchedMessagePut() then ownership of the memory is ceded to the

- *      the message will be expected to kfree() the message storage.
- *
- *  RETURNS

-	CsrTimeGet

-DESCRIPTION
-	Returns the current system time in a low and a high part. The low part

-
-	The caller may provide a NULL pointer as the high parameter.
-	In this case the function just returns the low part and ignores the
-	high parameter.
-
-	Although the time is expressed in microseconds the actual resolution is
-	platform dependent and can be less. It is recommended that the
-	resolution is at least 10 milliseconds.
-
-PARAMETERS
-	high - Pointer to variable that will receive the high part of the

- * - Function ----------------------------------------------------------------
- * card_hw_init()
- *
- *      Perform the initialisation procedure described in the UniFi Host
- *      Interface Protocol document (section 3.3.8) and read the run-time
- *      configuration information from the UniFi. This is stuff like number
- *      of bulk data slots etc.
- *
- *      The card enumeration and SD initialisation has already been done by
- *      the SDIO library, see card_sdio_init().
- *
- *      The initialisation is done when firmware is ready, i.e. this may need
- *      to be called after a f/w download operation.
- *
- *      The initialisation procedure goes like this:
- *       - Wait for UniFi to start-up by polling SHARED_MAILBOX1
- *       - Find the symbol table and look up SLT_SDIO_SLOT_CONFIG
- *       - Read the config structure
- *       - Check the "SDIO initialised" flag, if not zero do a h/w reset and
- *         start again
- *       - Decide the number of bulk data slots to allocate, allocate them and
- *         set "SDIO initialised" flag (and generate an interrupt) to say so.
- *
- * Arguments:
- *      card        Pointer to card struct
- *
- * Returns:
- *      CSR_RESULT_SUCEESS on success,
- *      a CSR error code on failure
- *
- * Notes:
- *      All data in the f/w is stored in a little endian format, without any
- *      padding bytes. Every read from this memory has to be transformed in
- *      host (cpu specific) format, before it is stored in driver's parameters
- *      or/and structures. Athough unifi_card_read16() and unifi_read32() do perform
- *      the conversion internally, unifi_readn() does not.

- * slots that this queue can actually use (may be higher than reserved slots and is dependent on reserved slots

- * unreserved slots sufficient for this request. If available these slots are reserved for the queue.
- * If there are not enough unreserved slots, a fair share for each queue is calculated based on the total slots
- * and the number of active queues (any queue with existing reservation is considered active). Queues needing
- * less than their fair share are allowed to have the previously reserved slots. The remaining slots are
- * distributed evenly among queues that need more than the fair share

- *
- *      The fh_signal_queue is later processed by the driver bottom half

- *      packets when:
- *        - the fh_signal_queue ring buffer is full
- *        - there are less than UNIFI_MAX_DATA_REFERENCES (2) bulk data
- *          slots available.
- *
- *  Arguments:
- *      card            Pointer to card context structure
- *      sigptr          Pointer to the signal to write to UniFi.
- *      siglen          Number of bytes pointer to by sigptr.
- *      bulkdata        Array of pointers to an associated bulk data.
- *      sigq            To which from-host queue to add the signal.
- *
- *  Returns:

-             * least one more check to see whether it needs to unpause the queue.  So all is well.

- *  PURPOSE:
- *      The traffic analysis sampling module.
- *      This gathers data which is sent to the SME and used to analyse
- *      the traffic behaviour.
- *
- * Provides:
- *      unifi_ta_sampling_init - Initialise the internal state
- *      unifi_ta_sample        - Sampling function, call this for every data packet
- *
- * Calls these external functions which must be provided:
- *      unifi_ta_indicate_sampling - Pass sample data to the SME.
- *      unifi_ta_indicate_protocol - Report certain data packet types to the SME.

- *
- * NOTES:
- *      Just call the UDI driver log fn directly for now.
- *      When done properly, each open() on the UDI device will install
- *      a log function. We will call all log fns whenever a signal is written
- *      to or read form the UniFi.

- *  xbv_to_patch
- *
- *      Convert (the relevant parts of) a firmware xbv file into a patch xbv
- *
- *  Arguments:
- *      card
- *      fw_buf - pointer to xbv firmware image
- *      fwinfo - structure describing the firmware image
- *      size   - pointer to location into which size of f/w is written.
- *
- *  Returns:
- *      Pointer to firmware image, or NULL on error. Caller must free this
- *      buffer via kfree() once it's finished with.
- *
- *  Notes:
- *      The input fw_buf should have been checked via xbv1_parse prior to
- *      calling this function, so the input image is assumed valid.

-  NAME
-    CsrWifiNmeSimUmtsAuthIndSend
-
-  DESCRIPTION
-    Indication generated from the NME (if an application subscribes to
-    receive it) that requests the UICC Manager to perform a UMTS
-    authentication on behalf of the NME. This indication is generated when
-    the NME is attempting to connect to a profile configured for EAP-AKA. An
-    application MUST register to receive this indication for the NME to
-    support the EAP-AKA credential types. Otherwise the NME has no route to
-    obtain the information from the USIM. EAP-AKA requires one UMTS
-    authentication round and therefore only one RAND and one AUTN values are
-    included.
-
-  PARAMETERS
-    queue  - Destination Task Queue
-    rand   - UMTS RAND value.
-    autn   - UMTS AUTN value.

-    The value of auts is only meaningful when
-    result=UMTS_AUTH_RESULT_SYNC_FAIL.
-
-  PARAMETERS
-    status             - Indicates the outcome of the requested operation:
-                         STATUS_SUCCESS or STATUS_ERROR.
-    result             - The result of UMTS authentication as performed by the
-                         UICC which could be: Success, Authentication Reject or
-                         Synchronisation Failure. For all these 3 outcomes the
-                         value of status is success.
-    umtsCipherKey      - The UMTS Cipher Key as calculated and returned by the
-                         UICC.
-    umtsIntegrityKey   - The UMTS Integrity Key as calculated and returned by
-                         the UICC.

-  NAME
-    CsrWifiNmeSimUmtsAuthInd
-
-  DESCRIPTION
-    Indication generated from the NME (if an application subscribes to
-    receive it) that requests the UICC Manager to perform a UMTS
-    authentication on behalf of the NME. This indication is generated when
-    the NME is attempting to connect to a profile configured for EAP-AKA. An
-    application MUST register to receive this indication for the NME to
-    support the EAP-AKA credential types. Otherwise the NME has no route to
-    obtain the information from the USIM. EAP-AKA requires one UMTS
-    authentication round and therefore only one RAND and one AUTN values are
-    included.
-
-  MEMBERS
-    common - Common header for use with the CsrWifiFsm Module
-    rand   - UMTS RAND value.
-    autn   - UMTS AUTN value.

-  NAME
-    CsrWifiRouterMaPacketCancelReqSend
-
-  DESCRIPTION
-    This primitive is used to request cancellation of a previously send
-    CsrWifiRouterMaPacketReq.
-    The frame may already have been transmitted so there is no guarantees
-    that the CsrWifiRouterMaPacketCancelReq actually cancels the transmission
-    of the frame in question.
-    If the cancellation fails, the Router will send, if required,
-    CsrWifiRouterMaPacketCfm.
-    If the cancellation succeeds, the Router will not send
-    CsrWifiRouterMaPacketCfm.
-
-  PARAMETERS
-    queue          - Message Source Task Queue (Cfm's will be sent to this Queue)
-    interfaceTag   - Interface Identifier; unique identifier of an interface
-    hostTag        - The hostTag for the frame, which should be cancelled.
-    priority       - Priority of the frame, which should be cancelled
-    peerMacAddress - Destination MAC address of the frame, which should be
-                     cancelled

-    freeFunction       - Pointer to function to be used to free the frame
-    priority           - Priority of the frame, which should be sent
-    hostTag            - An application shall set the bits b31..b28 using one of
-                         the CSR_WIFI_ROUTER_APP_TYPE_* masks. Bits b0..b27 can
-                         be used by the requestor without any restrictions, but
-                         the hostTag shall be unique so the hostTag for

-
-  NAME
-    CsrWifiSmeConnectReqSend
-
-  DESCRIPTION
-    The wireless manager application calls this primitive to start the
-    process of joining an 802.11 wireless network or to start an ad hoc
-    network.
-    The structure pointed by connectionConfig contains parameters describing
-    the network to join or, in case of an ad hoc network, to host or join.
-    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
-    and Associate exchanges.
-    The SME selects the networks from the current scan list that match both
-    the SSID and BSSID, however either or both of these may be the wildcard
-    value. Using this rule, the following operations are possible:
-      * To connect to a network by name, specify the SSID and set the BSSID to
-        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
-        the SME will select the one with the strongest signal.
-      * To connect to a specific network, specify the BSSID. The SSID is
-        optional, but if given it must match the SSID of the network. An empty
-        SSID may be specified by setting the SSID length to zero. Please note
-        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
-        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
-        poor, even if there is an alternative AP with an SSID that matches the
-        current network SSID.
-      * To connect to any network matching the other parameters (i.e. security,
-        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
-        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
-        by their signal strengths and will iterate through this list until it
-        successfully connects.
-    NOTE: Specifying the BSSID will restrict the selection to one specific
-    network. If SSID and BSSID are given, they must both match the network
-    for it to be selected. To select a network based on the SSID only, the
-    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
-    0xFF 0xFF.
-    The SME will try to connect to each network that matches the provided
-    parameters, one by one, until it succeeds or has tried unsuccessfully
-    with all the matching networks.
-    If there is no network that matches the parameters and the request allows
-    to host an ad hoc network, the SME will advertise a new ad hoc network
-    instead.
-    If the SME cannot connect, it will notify the failure in the confirm.
-
-  PARAMETERS
-    queue            - Message Source Task Queue (Cfm's will be sent to this Queue)

-
-  NAME
-    CsrWifiSmePacketFilterSetReqSend
-
-  DESCRIPTION
-    The wireless manager application should call this primitive to enable or
-    disable filtering of broadcast packets: uninteresting broadcast packets
-    will be dropped by the Wi-Fi chip, instead of passing them up to the
-    host.
-    This has the advantage of saving power in the host application processor
-    as it removes the need to process unwanted packets.
-    All broadcast packets are filtered according to the filter and the filter
-    mode provided, except ARP packets, which are filtered using
-    arpFilterAddress.
-    Filters are not cumulative: only the parameters specified in the most
-    recent successful request are significant.
-    For more information, see 'UniFi Firmware API Specification'.
-
-  PARAMETERS
-    queue            - Message Source Task Queue (Cfm's will be sent to this Queue)
-    interfaceTag     - Interface Identifier; unique identifier of an interface
-    filterLength     - Length of the filter in bytes.
-                       filterLength=0 disables the filter previously set
-    filter           - Points to the first byte of the filter provided, if any.
-                       This shall include zero or more instance of the
-                       information elements of one of these types
-                         * Traffic Classification (TCLAS) elements
-                         * WMM-SA TCLAS elements
-    mode             - Specifies whether the filter selects or excludes packets
-                       matching the filter
-    arpFilterAddress - IPv4 address to be used for filtering the ARP packets.
-                         * If the specified address is the IPv4 broadcast address
-                           (255.255.255.255), all ARP packets are reported to the
-                           host,
-                         * If the specified address is NOT the IPv4 broadcast
-                           address, only ARP packets with the specified address in
-                           the Source or Target Protocol Address fields are reported

-  NAME
-    CsrWifiSmeRoamStartIndSend
-
-  DESCRIPTION
-    The SME will send this primitive to all the tasks that have registered to
-    receive it whenever it begins an attempt to roam to an AP.
-    If the wireless manager application connect request specified the SSID
-    and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
-    0xFF), the SME monitors the signal quality and maintains a list of
-    candidates to roam to. When the signal quality of the current connection
-    falls below a threshold, and there is a candidate with better quality,
-    the SME will attempt to the candidate AP.
-    If the roaming procedure succeeds, the SME will also issue a Media
-    Connect indication to inform the wireless manager application of the
-    change.
-    NOTE: to prevent the SME from initiating roaming the WMA must specify the
-    BSSID in the connection request; this forces the SME to connect only to
-    that AP.
-    The wireless manager application can obtain statistics for roaming
-    purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
-    CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
-    When the wireless manager application wishes to roam to another AP, it
-    must issue a connection request specifying the BSSID of the desired AP.

-    CsrWifiSmeScanResultsFlushReqSend
-
-  DESCRIPTION
-    The Wireless Manager calls this primitive to ask the SME to delete all
-    scan results from its cache, except for the scan result of any currently
-    connected network.
-    As scan results are received by the SME from the firmware, they are
-    cached in the SME memory.
-    Any time the Wireless Manager requests scan results, they are returned
-    from the SME internal cache.
-    For some applications it may be desirable to clear this cache prior to
-    requesting that a scan be performed; this will ensure that the cache then
-    only contains the networks detected in the most recent scan.

-  NAME
-    CsrWifiSmeTspecReqSend
-
-  DESCRIPTION
-    The wireless manager application should call this primitive to use the
-    TSPEC feature.
-    The chip supports the use of TSPECs and TCLAS for the use of IEEE
-    802.11/WMM Quality of Service features.
-    The API allows the wireless manager application to supply a correctly
-    formatted TSPEC and TCLAS pair to the driver.
-    After performing basic validation, the driver negotiates the installation
-    of the TSPEC with the AP as defined by the 802.11 specification.
-    The driver retains all TSPEC and TCLAS pairs until they are specifically
-    removed.
-    It is not compulsory for a TSPEC to have a TCLAS (NULL is used to
-    indicate that no TCLAS is supplied), while a TCLASS always require a
-    TSPEC.
-    The format of the TSPEC element is specified in 'WMM (including WMM Power
-    Save) Specification - Version 1.1' and 'ANSI/IEEE Std 802.11-REVmb/D3.0'.
-    For more information, see 'UniFi Configuring WMM and WMM-PS'.
-
-  PARAMETERS
-    queue         - Message Source Task Queue (Cfm's will be sent to this Queue)
-    interfaceTag  - Interface Identifier; unique identifier of an interface
-    action        - Specifies the action to be carried out on the list of TSPECs.
-                    CSR_WIFI_SME_LIST_ACTION_FLUSH is not applicable here.
-    transactionId - Unique Transaction ID for the TSPEC, as assigned by the
-                    driver
-    strict        - If it set to false, allows the SME to perform automatic
-                    TSPEC negotiation
-    ctrlMask      - Additional TSPEC configuration for CCX.
-                    Set mask with values from CsrWifiSmeTspecCtrl.
-                    CURRENTLY NOT SUPPORTED
-    tspecLength   - Length of the TSPEC.
-    tspec         - Points to the first byte of the TSPEC
-    tclasLength   - Length of the TCLAS.
-                    If it is equal to 0, no TCLASS is provided for the TSPEC
-    tclas         - Points to the first byte of the TCLAS, if any.

-
-  NAME
-    CsrWifiSmeWifiFlightmodeReqSend
-
-  DESCRIPTION
-    The wireless manager application may call this primitive on boot-up of
-    the platform to ensure that the chip is placed in a mode that prevents
-    any emission of RF energy.
-    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
-    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
-    (if any) and the programming of the initial MIB settings (if supplied by
-    the WMA), but it also ensures that the chip is left in its lowest
-    possible power-mode with the radio subsystems disabled.
-    This feature is useful on platforms where power cannot be removed from
-    the chip (leaving the chip not initialised will cause it to consume more
-    power so calling this function ensures that the chip is initialised into
-    a low power mode but without entering a state where it could emit any RF
-    energy).
-    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
-    stays conceptually off. Configuration primitives can be sent after
-    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
-    Requests that require the state of the Wi-Fi to be ON will return
-    CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.
-
-  PARAMETERS
-    queue         - Message Source Task Queue (Cfm's will be sent to this Queue)
-    address       - Optionally specifies a station MAC address.
-                    In normal use, the manager should set the address to 0xFF
-                    0xFF 0xFF 0xFF 0xFF 0xFF, which will cause the chip to use
-                    the MAC address in the MIB.
-    mibFilesCount - Number of provided data blocks with initial MIB values
-    mibFiles      - Points to the first data block with initial MIB values.
-                    These data blocks are typically the contents of the provided
-                    files ufmib.dat and localmib.dat, available from the host
-                    file system, if they exist.
-                    These files typically contain radio tuning and calibration
-                    values.
-                    More values can be created using the Host Tools.

-  NAME
-    CsrWifiSmeConnectReq
-
-  DESCRIPTION
-    The wireless manager application calls this primitive to start the
-    process of joining an 802.11 wireless network or to start an ad hoc
-    network.
-    The structure pointed by connectionConfig contains parameters describing
-    the network to join or, in case of an ad hoc network, to host or join.
-    The SME will select a network, perform the IEEE 802.11 Join, Authenticate
-    and Associate exchanges.
-    The SME selects the networks from the current scan list that match both
-    the SSID and BSSID, however either or both of these may be the wildcard
-    value. Using this rule, the following operations are possible:
-      * To connect to a network by name, specify the SSID and set the BSSID to
-        0xFF 0xFF 0xFF 0xFF 0xFF 0xFF. If there are two or more networks visible,
-        the SME will select the one with the strongest signal.
-      * To connect to a specific network, specify the BSSID. The SSID is
-        optional, but if given it must match the SSID of the network. An empty
-        SSID may be specified by setting the SSID length to zero. Please note
-        that if the BSSID is specified (i.e. not equal to 0xFF 0xFF 0xFF 0xFF
-        0xFF 0xFF), the SME will not attempt to roam if signal conditions become
-        poor, even if there is an alternative AP with an SSID that matches the
-        current network SSID.
-      * To connect to any network matching the other parameters (i.e. security,
-        etc), set the SSID length to zero and set the BSSID to 0xFF 0xFF 0xFF
-        0xFF 0xFF 0xFF. In this case, the SME will order all available networks
-        by their signal strengths and will iterate through this list until it
-        successfully connects.
-    NOTE: Specifying the BSSID will restrict the selection to one specific
-    network. If SSID and BSSID are given, they must both match the network
-    for it to be selected. To select a network based on the SSID only, the
-    wireless manager application must set the BSSID to 0xFF 0xFF 0xFF 0xFF
-    0xFF 0xFF.
-    The SME will try to connect to each network that matches the provided
-    parameters, one by one, until it succeeds or has tried unsuccessfully
-    with all the matching networks.
-    If there is no network that matches the parameters and the request allows
-    to host an ad hoc network, the SME will advertise a new ad hoc network
-    instead.
-    If the SME cannot connect, it will notify the failure in the confirm.

-  DESCRIPTION
-    The wireless manager application may call this primitive on boot-up of
-    the platform to ensure that the chip is placed in a mode that prevents
-    any emission of RF energy.
-    This primitive is an alternative to CSR_WIFI_SME_WIFI_ON_REQ.
-    As in CSR_WIFI_SME_WIFI_ON_REQ, it causes the download of the patch file
-    (if any) and the programming of the initial MIB settings (if supplied by
-    the WMA), but it also ensures that the chip is left in its lowest
-    possible power-mode with the radio subsystems disabled.
-    This feature is useful on platforms where power cannot be removed from
-    the chip (leaving the chip not initialised will cause it to consume more
-    power so calling this function ensures that the chip is initialised into
-    a low power mode but without entering a state where it could emit any RF
-    energy).
-    NOTE: this primitive does not cause the Wi-Fi to change state: Wi-Fi
-    stays conceptually off. Configuration primitives can be sent after
-    CSR_WIFI_SME_WIFI_FLIGHTMODE_REQ and the configuration will be maintained.
-    Requests that require the state of the Wi-Fi to be ON will return
-    CSR_WIFI_SME_STATUS_WIFI_OFF in their confirms.

-    The SME will send this primitive to all the tasks that have registered to

-    If the wireless manager application connect request specified the SSID
-    and the BSSID was set to the broadcast address (0xFF 0xFF 0xFF 0xFF 0xFF
-    0xFF), the SME monitors the signal quality and maintains a list of
-    candidates to roam to. When the signal quality of the current connection
-    falls below a threshold, and there is a candidate with better quality,
-    the SME will attempt to the candidate AP.
-    If the roaming procedure succeeds, the SME will also issue a Media
-    Connect indication to inform the wireless manager application of the
-    change.
-    NOTE: to prevent the SME from initiating roaming the WMA must specify the
-    BSSID in the connection request; this forces the SME to connect only to
-    that AP.
-    The wireless manager application can obtain statistics for roaming
-    purposes using CSR_WIFI_SME_CONNECTION_QUALITY_IND and
-    CSR_WIFI_SME_CONNECTION_STATS_GET_REQ.
-    When the wireless manager application wishes to roam to another AP, it
-    must issue a connection request specifying the BSSID of the desired AP.

- * Porting Notes:
- * Part of this file contains an example for how to glue the OS layer
- * with the HIP core lib, the SDIO glue layer, and the SME.
- *
- * When the unifi_sdio.ko modules loads, the linux kernel calls unifi_load().
- * unifi_load() calls uf_sdio_load() which is exported by the SDIO glue
- * layer. uf_sdio_load() registers this driver with the underlying SDIO driver.
- * When a card is detected, the SDIO glue layer calls register_unifi_sdio()
- * to pass the SDIO function context and ask the OS layer to initialise
- * the card. register_unifi_sdio() allocates all the private data of the OS
- * layer and calls uf_run_unifihelper() to start the SME. The SME calls
- * unifi_sys_wifi_on_req() which uses the HIP core lib to initialise the card.

- *  FILE:     io.c
- *
- *  PURPOSE:
- *      This file contains routines that the SDIO driver can call when a
- *      UniFi card is first inserted (or detected) and removed.
- *
- *      When used with sdioemb, the udev scripts (at least on Ubuntu) don't
- *      recognise a UniFi being added to the system. This is because sdioemb
- *      does not register itself as a device_driver, it uses it's own code
- *      to handle insert and remove.
- *      To have Ubuntu recognise UniFi, edit /etc/udev/rules.d/85-ifupdown.rules
- *      to change this line:
- *          SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
- *      to these:
- *          #SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
- *          SUBSYSTEM=="net", GOTO="net_start"
- *
- *      Then you can add a stanza to /etc/network/interfaces like this:
- *          auto eth1
- *          iface eth1 inet dhcp
- *          wpa-conf /etc/wpa_supplicant.conf
- *      This will then automatically associate when a car dis inserted.
- *

-/*
- * Porting Notes:
- * This file implements the data plane of the UniFi linux driver.
- *
- * All the Tx packets are passed to the HIP core lib, using the
- * unifi_send_signal() API. For EAPOL packets use the MLME-EAPOL.req
- * signal, for all other use the MLME-UNITDATA.req. The unifi_send_signal()
- * expects the wire-formatted (packed) signal. For convenience, in the OS
- * layer we only use the native (unpacked) signal structures. The HIP core lib
- * provides the write_pack() helper function to convert to the packed signal.
- * The packet is stored in the bulk data of the signal. We do not need to
- * allocate new memory to store the packet, because unifi_net_data_malloc()
- * is implemented to return a skb, which is the format of packet in Linux.
- * The HIP core lib frees the bulk data buffers, so we do not need to do
- * this in the OS layer.
- *
- * All the Rx packets are MLME-UNITDATA.ind signals, passed by the HIP core lib
- * in unifi_receive_event(). We do not need to allocate an skb and copy the
- * received packet because the HIP core lib has stored in memory allocated by
- * unifi_net_data_malloc(). Also, we can perform the 802.11 to Ethernet
- * translation in-place because we allocate the extra memory allocated in
- * unifi_net_data_malloc().
- *
- * If possible, the porting exercise should appropriately implement
- * unifi_net_data_malloc() and unifi_net_data_free() to save copies between
- * network and driver buffers.

- * This file also contains the implementation of the asynchronous
- * requests to the SME.
- *
- * Before calling an asynchronous SME function, we call sme_init_request()
- * which gets hold of the SME semaphore and updates the request status.
- * The semaphore makes sure that there is only one pending request to
- * the SME at a time.
- *
- * Now we are ready to call the SME function, but only if
- * sme_init_request() has returned 0.
- *
- * When the SME function returns, we need to wait
- * for the reply. This is done in sme_wait_for_reply().
- * If the request times-out, the request status is set to SME_REQUEST_TIMEDOUT
- * and the sme_wait_for_reply() returns.
- *
- * If the SME replies in time, we call sme_complete_request().
- * There we change the request status to SME_REQUEST_RECEIVED. This will
- * wake up the process waiting on sme_wait_for_reply().
- * It is important that we copy the reply data in priv->sme_reply
- * before calling sme_complete_request().
- *
- * Handling the wext requests, we need to block
- * until the SME sends the response to our request.
- * We use the sme_init_request() and sme_wait_for_reply()
- * to implement this behavior in the following functions:
- * sme_mgt_wifi_on()
- * sme_mgt_wifi_off()
- * sme_mgt_scan_full()

- *
- *  Arguments:

- *
- *  Returns:

- *
- *  Notes:
- *  The signals are received in the format described in the host interface
- *  specification, i.e wire formatted. Certain clients use the same format
- *  to interpret them and other clients use the host formatted structures.
- *  Each client has to call read_unpack_signal() to transform the wire

- *  The code is in the core, since the signals are defined therefore
- *  binded to the host interface specification.

- * Since some of CSR SDIO API is used regardless of trying to lock unifi_bh()
- * we have followed this scheme:
- * 1. If a function needs protection only when CSR_WIFI_SINGLE_FUNCTION is defined
- *    then we call CsrSdioClaim/CsrSdioRelease().
- * 2. If a function needs protection only when CSR_WIFI_SINGLE_FUNCTION is not defined
- *    then we call _sdio_claim_host/_sdio_claim_host(). Use of this should be restricted
- *    to the SDIO glue layer only (e.g. sdio_mmc.c).
- * 3. If a function needs protection, regardless of the CSR_WIFI_SINGLE_FUNCTION
- *    then we call directly the sdio_claim_host/sdio_release_host().
- *    Use of this must be restricted to the SDIO glue layer only (e.g. sdio_mmc.c).
- *
- * Note: The _func and function pointers are _not_ the same.
- * The former is the (struct sdio_func*) context, which restricts the use to the SDIO glue layer.
- * The latter is the (CsrSdioFunction*) context, which allows calls from all layers.

-* Texas Instrument OMAP SCM bandgap bindings
-
-In the System Control Module, OMAP supplies a voltage reference
-and a temperature sensor feature that are gathered in the band
-gap voltage and temperature sensor (VBGAPTS) module. The band
-gap provides current and voltage reference for its internal
-circuits and other analog IP blocks. The analog-to-digital
-converter (ADC) produces an output value that is proportional
-to the silicon temperature.
-
-Required properties:
-- compatible : Should be:
-  - "ti,omap4430-bandgap" : for OMAP4430 bandgap
-  - "ti,omap4460-bandgap" : for OMAP4460 bandgap
-  - "ti,omap4470-bandgap" : for OMAP4470 bandgap
-  - "ti,omap5430-bandgap" : for OMAP5430 bandgap
-- interrupts : this entry should indicate which interrupt line
-the talert signal is routed to;
-Specific:
-- ti,tshut-gpio : this entry should be used to inform which GPIO
-line the tshut signal is routed to;
-- regs : this entry must also be specified and it is specific
-to each bandgap version, because the mapping may change from
-soc to soc, apart of depending on available features.
-
-Example:
-OMAP4430:
-bandgap {
-	reg = <0x4a002260 0x4 0x4a00232C 0x4>;
-	compatible = "ti,omap4430-bandgap";
