+ * struct sx150x_platform_data - config data for SX150x driver
+ * @gpio_base: The index number of the first GPIO assigned to this
+ *             GPIO expander.  The expander will create a block of
+ *             consecutively numbered gpios beginning at the given base,
+ *             with the size of the block depending on the model of the
+ *             expander chip.
+ * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
+ *                instead of as an oscillator, increasing the size of the
+ *                GP(I)O pool created by this expander by one.  The
+ *                output-only GPO pin will be added at the end of the block.
+ * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
+ *                 for each IO line in the expander.  Setting the bit at
+ *                 position n will enable the pull-up for the IO at
+ *                 the corresponding offset.  For chips with fewer than
+ *                 16 IO pins, high-end bits are ignored.
+ * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
+ *                 resistor for each IO line in the expander. Setting the
+ *                 bit at position n will enable the pull-down for the IO at
+ *                 the corresponding offset.  For chips with fewer than
+ *                 16 IO pins, high-end bits are ignored.
+ * @io_polarity: A bit-mask which enables polarity inversion for each IO line
+ *               in the expander.  Setting the bit at position n inverts
+ *               the polarity of that IO line, while clearing it results
+ *               in normal polarity. For chips with fewer than 16 IO pins,
+ *               high-end bits are ignored.
+ * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
+ *               is connected, via which it reports interrupt events
+ *               across all GPIO lines.  This must be a real,
+ *               pre-existing IRQ line.
+ *               Setting this value < 0 disables the irq_chip functionality
+ *               of the driver.
+ * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
+ *            IRQ lines will appear.  Similarly to gpio_base, the expander
+ *            will create a block of irqs beginning at this number.
+ *            This value is ignored if irq_summary is < 0.
+ * @reset_during_probe: If set to true, the driver will trigger a full
+ *                      reset of the chip at the beginning of the probe
+ *                      in order to place it in a known state.

+ * DOC: framebuffer cma helper functions
+ *
+ * Provides helper functions for creating a cma (contiguous memory allocator)
+ * backed framebuffer.
+ *
+ * drm_fb_cma_create() is used in the &drm_mode_config_funcs ->fb_create
+ * callback function to create a cma backed framebuffer.
+ *
+ * An fbdev framebuffer backed by cma is also available by calling
+ * drm_fbdev_cma_init(). drm_fbdev_cma_fini() tears it down.
+ * If the &drm_framebuffer_funcs ->dirty callback is set, fb_deferred_io
+ * will be set up automatically. dirty() is called by
+ * drm_fb_helper_deferred_io() in process context (struct delayed_work).

+ * The single GEM object described here is actually made up of several
+ * separate areas, as far as the GuC is concerned. The first page (kept

+ * the doorbell, and one cacheline which actually *is* the doorbell; a
+ * write to this will "ring the doorbell" (i.e. send an interrupt to the
+ * GuC). The subsequent  pages of the client object constitute the work
+ * queue (a circular array of work items), again described in the process
+ * descriptor. Work queue pages are mapped momentarily as required.

+ * 1. Under stress-testing, it has been observed that the PCIe link
+ * goes down, without reason. Therefore, the driver takes special care
+ * to allow device hot-unplugging.
+ *
+ * 2. TW686X devices are capable of setting a few different DMA modes,
+ * including: scatter-gather, field and frame modes. However,
+ * under stress testings it has been found that the machine can
+ * freeze completely if DMA registers are programmed while streaming
+ * is active.
+ * This driver tries to access hardware registers as infrequently
+ * as possible by:
+ *   i.  allocating fixed DMA buffers and memcpy'ing into
+ *       vmalloc'ed buffers
+ *   ii. using a timer to mitigate the rate of DMA reset operations,
+ *       on DMA channels error.

+ * The Flexible Power Sequencer (FPS) allows each regulator to power up under
+ * hardware or software control. Additionally, each regulator can power on
+ * independently or among a group of other regulators with an adjustable
+ * power-up and power-down delays (sequencing). GPIO1, GPIO2, and GPIO3 can
+ * be programmed to be part of a sequence allowing external regulators to be
+ * sequenced along with internal regulators. 32KHz clock can be programmed to
+ * be part of a sequence.
+ * There is 3 FPS confguration registers and all resources are configured to
+ * any of these FPS or no FPS.

-/*
- * Design
- *
- * This is a generic 5380 driver.  To use it on a different platform,
- * one simply writes appropriate system specific macros (ie, data
- * transfer - some PC's will use the I/O bus, 68K's must use
- * memory mapped) and drops this file in their 'C' wrapper.
- *
- * As far as command queueing, two queues are maintained for
- * each 5380 in the system - commands that haven't been issued yet,
- * and commands that are currently executing.  This means that an
- * unlimited number of commands may be queued, letting
- * more commands propagate from the higher driver levels giving higher
- * throughput.  Note that both I_T_L and I_T_L_Q nexuses are supported,
- * allowing multiple commands to propagate all the way to a SCSI-II device
- * while a command is already executing.
- *
- *
- * Issues specific to the NCR5380 :
- *
- * When used in a PIO or pseudo-dma mode, the NCR5380 is a braindead
- * piece of hardware that requires you to sit in a loop polling for
- * the REQ signal as long as you are connected.  Some devices are
- * brain dead (ie, many TEXEL CD ROM drives) and won't disconnect
- * while doing long seek operations. [...] These
- * broken devices are the exception rather than the rule and I'd rather
- * spend my time optimizing for the normal case.
- *
- * Architecture :
- *
- * At the heart of the design is a coroutine, NCR5380_main,
- * which is started from a workqueue for each NCR5380 host in the
- * system.  It attempts to establish I_T_L or I_T_L_Q nexuses by
- * removing the commands from the issue queue and calling
- * NCR5380_select() if a nexus is not established.
- *
- * Once a nexus is established, the NCR5380_information_transfer()
- * phase goes through the various phases as instructed by the target.
- * if the target goes into MSG IN and sends a DISCONNECT message,
- * the command structure is placed into the per instance disconnected
- * queue, and NCR5380_main tries to find more work.  If the target is
- * idle for too long, the system will try to sleep.
- *
- * If a command has disconnected, eventually an interrupt will trigger,
- * calling NCR5380_intr()  which will in turn call NCR5380_reselect
- * to reestablish a nexus.  This will run main if necessary.
- *
- * On command termination, the done function will be called as
- * appropriate.
- *
- * SCSI pointers are maintained in the SCp field of SCSI command
- * structures, being initialized after the command is connected
- * in NCR5380_select, and set as appropriate in NCR5380_information_transfer.
- * Note that in violation of the standard, an implicit SAVE POINTERS operation
- * is done, since some BROKEN disks fail to issue an explicit SAVE POINTERS.

- * Using this file :

- * These macros control options :

- * Functions for handling tagged queuing
- * =====================================
- *
- * ++roman (01/96): Now I've implemented SCSI-2 tagged queuing. Some notes:
- *
- * Using consecutive numbers for the tags is no good idea in my eyes. There
- * could be wrong re-usings if the counter (8 bit!) wraps and some early
- * command has been preempted for a long time. My solution: a bitfield for
- * remembering used tags.
- *
- * There's also the problem that each target has a certain queue size, but we
- * cannot know it in advance :-( We just see a QUEUE_FULL status being
- * returned. So, in this case, the driver internal queue size assumption is
- * reduced to the number of active tags if QUEUE_FULL is returned by the
- * target.
- *
- * We're also not allowed running tagged commands as long as an untagged
- * command is active. And REQUEST SENSE commands after a contingent allegiance
- * condition _must_ be untagged. To keep track whether an untagged command has
- * been issued, the host->busy array is still employed, as it is without
- * support for tagged queuing.
- *
- * One could suspect that there are possible race conditions between
- * is_lun_busy(), cmd_get_tag() and cmd_free_tag(). But I think this isn't the
- * case: is_lun_busy() and cmd_get_tag() are both called from NCR5380_main(),
- * which already guaranteed to be running at most once. It is also the only
- * place where tags/LUNs are allocated. So no other allocation can slip
- * between that pair, there could only happen a reselection, which can free a
- * tag, but that doesn't hurt. Only the sequence in cmd_free_tag() becomes
- * important: the tag bit must be cleared before 'nr_allocated' is decreased.

- * Handle interrupts, reestablishing I_T_L or I_T_L_Q nexuses
- * from the disconnected queue, and restarting NCR5380_main()
- * as required.
- *
- * The chip can assert IRQ in any of six different conditions. The IRQ flag
- * is then cleared by reading the Reset Parity/Interrupt Register (RPIR).
- * Three of these six conditions are latched in the Bus and Status Register:
- * - End of DMA (cleared by ending DMA Mode)
- * - Parity error (cleared by reading RPIR)
- * - Loss of BSY (cleared by reading RPIR)
- * Two conditions have flag bits that are not latched:
- * - Bus phase mismatch (non-maskable in DMA Mode, cleared by ending DMA Mode)
- * - Bus reset (non-maskable)
- * The remaining condition has no flag bit at all:
- * - Selection/reselection
- *
- * Hence, establishing the cause(s) of any interrupt is partly guesswork.
- * In "The DP8490 and DP5380 Comparison Guide", National Semiconductor
- * claimed that "the design of the [DP8490] interrupt logic ensures
- * interrupts will not be lost (they can be on the DP5380)."
- * The L5380/53C80 datasheet from LOGIC Devices has more details.
- *
- * Checking for bus reset by reading RST is futile because of interrupt
- * latency, but a bus reset will reset chip logic. Checking for parity error
- * is unnecessary because that interrupt is never enabled. A Loss of BSY
- * condition will clear DMA Mode. We can tell when this occurs because the
- * the Busy Monitor interrupt is enabled together with DMA Mode.

-Options:
-	[0] - base io address
-	[1] - irq (optional, required for timed or externally triggered conversions)
-	[2] - dma0 (optional, requires irq)
-	[3] - dma1 (optional, requires irq and dma0)
-
-irq can be omitted, although the cmd interface will not work without it.
-
-analog input cmd triggers supported:
-	start_src:      TRIG_NOW | TRIG_EXT
-	scan_begin_src: TRIG_FOLLOW | TRIG_TIMER | TRIG_EXT
-	scan_end_src:   TRIG_COUNT
-	convert_src:    TRIG_TIMER | TRIG_EXT (TRIG_EXT requires scan_begin_src == TRIG_FOLLOW)
-	stop_src:       TRIG_COUNT | TRIG_EXT | TRIG_NONE
-
-scan_begin_src triggers TRIG_TIMER and TRIG_EXT use the card's
-'burst mode' which limits the valid conversion time to 64 microseconds
-(convert_arg <= 64000).  This limitation does not apply if scan_begin_src
-is TRIG_FOLLOW.
-
-NOTES:
-Only the DAS-1801ST has been tested by me.
-Unipolar and bipolar ranges cannot be mixed in the channel/gain list.
-
-TODO:
-	Make it automatically allocate irq and dma channels if they are not specified
-	Add support for analog out on 'ao' cards
-	read insn for analog out

+ *   [2] - DMA0 (optional, requires irq)
+ *   [3] - DMA1 (optional, requires irq and dma0)
+ *
+ * analog input cmd triggers supported:
+ *
+ *   start_src		TRIG_NOW	command starts immediately
+ *			TRIG_EXT	command starts on external pin TGIN
+ *
+ *   scan_begin_src	TRIG_FOLLOW	paced/external scans start immediately
+ *			TRIG_TIMER	burst scans start periodically
+ *			TRIG_EXT	burst scans start on external pin XPCLK
+ *
+ *   scan_end_src	TRIG_COUNT	scan ends after last channel
+ *
+ *   convert_src	TRIG_TIMER	paced/burst conversions are timed
+ *			TRIG_EXT	conversions on external pin XPCLK
+ *					(requires scan_begin_src == TRIG_FOLLOW)
+ *
+ *   stop_src		TRIG_COUNT	command stops after stop_arg scans
+ *			TRIG_EXT	command stops on external pin TGIN
+ *			TRIG_NONE	command runs until canceled
+ *
+ * If TRIG_EXT is used for both the start_src and stop_src, the first TGIN
+ * trigger starts the command, and the second trigger will stop it. If only
+ * one is TRIG_EXT, the first trigger will either stop or start the command.
+ * The external pin TGIN is normally set for negative edge triggering. It
+ * can be set to positive edge with the CR_INVERT flag. If TRIG_EXT is used
+ * for both the start_src and stop_src they must have the same polarity.
+ *
+ * Minimum conversion speed is limited to 64 microseconds (convert_arg <= 64000)
+ * for 'burst' scans. This limitation does not apply for 'paced' scans. The
+ * maximum conversion speed is limited by the board (convert_arg >= ai_speed).
+ * Maximum conversion speeds are not always achievable depending on the
+ * board setup (see user manual).
+ *
+ * NOTES:
+ * Only the DAS-1801ST has been tested by me.
+ * Unipolar and bipolar ranges cannot be mixed in the channel/gain list.
+ *
+ * The waveform analog output on the 'ao' cards is not supported.

  * LIFE CYCLE
  *
- * cl_lock is reference counted. When reference counter drops to 0, lock is
- * placed in the cache, except when lock is in CLS_FREEING state. CLS_FREEING
- * lock is destroyed when last reference is released. Referencing between
- * top-lock and its sub-locks is described in the lov documentation module.
- *
- * STATE MACHINE
- *
- * Also, cl_lock is a state machine. This requires some clarification. One of
- * the goals of client IO re-write was to make IO path non-blocking, or at
- * least to make it easier to make it non-blocking in the future. Here
- * `non-blocking' means that when a system call (read, write, truncate)
- * reaches a situation where it has to wait for a communication with the
- * server, it should --instead of waiting-- remember its current state and
- * switch to some other work.  E.g,. instead of waiting for a lock enqueue,
- * client should proceed doing IO on the next stripe, etc. Obviously this is
- * rather radical redesign, and it is not planned to be fully implemented at
- * this time, instead we are putting some infrastructure in place, that would
- * make it easier to do asynchronous non-blocking IO easier in the
- * future. Specifically, where old locking code goes to sleep (waiting for
- * enqueue, for example), new code returns cl_lock_transition::CLO_WAIT. When
- * enqueue reply comes, its completion handler signals that lock state-machine
- * is ready to transit to the next state. There is some generic code in
- * cl_lock.c that sleeps, waiting for these signals. As a result, for users of
- * this cl_lock.c code, it looks like locking is done in normal blocking
- * fashion, and it the same time it is possible to switch to the non-blocking
- * locking (simply by returning cl_lock_transition::CLO_WAIT from cl_lock.c
- * functions).
- *
- * For a description of state machine states and transitions see enum
- * cl_lock_state.
- *
- * There are two ways to restrict a set of states which lock might move to:
- *
- *     - placing a "hold" on a lock guarantees that lock will not be moved
- *       into cl_lock_state::CLS_FREEING state until hold is released. Hold
- *       can be only acquired on a lock that is not in
- *       cl_lock_state::CLS_FREEING. All holds on a lock are counted in
- *       cl_lock::cll_holds. Hold protects lock from cancellation and
- *       destruction. Requests to cancel and destroy a lock on hold will be
- *       recorded, but only honored when last hold on a lock is released;
- *
- *     - placing a "user" on a lock guarantees that lock will not leave
- *       cl_lock_state::CLS_NEW, cl_lock_state::CLS_QUEUING,
- *       cl_lock_state::CLS_ENQUEUED and cl_lock_state::CLS_HELD set of
- *       states, once it enters this set. That is, if a user is added onto a
- *       lock in a state not from this set, it doesn't immediately enforce
- *       lock to move to this set, but once lock enters this set it will
- *       remain there until all users are removed. Lock users are counted in
- *       cl_lock::cll_users.
- *
- *       User is used to assure that lock is not canceled or destroyed while
- *       it is being enqueued, or actively used by some IO.
- *
- *       Currently, a user always comes with a hold (cl_lock_invariant()
- *       checks that a number of holds is not less than a number of users).
- *
- * CONCURRENCY
- *
- * This is how lock state-machine operates. struct cl_lock contains a mutex
- * cl_lock::cll_guard that protects struct fields.
- *
- *     - mutex is taken, and cl_lock::cll_state is examined.
- *
- *     - for every state there are possible target states where lock can move
- *       into. They are tried in order. Attempts to move into next state are
- *       done by _try() functions in cl_lock.c:cl_{enqueue,unlock,wait}_try().
- *
- *     - if the transition can be performed immediately, state is changed,
- *       and mutex is released.
- *
- *     - if the transition requires blocking, _try() function returns
- *       cl_lock_transition::CLO_WAIT. Caller unlocks mutex and goes to
- *       sleep, waiting for possibility of lock state change. It is woken
- *       up when some event occurs, that makes lock state change possible
- *       (e.g., the reception of the reply from the server), and repeats
- *       the loop.
- *
- * Top-lock and sub-lock has separate mutexes and the latter has to be taken
- * first to avoid dead-lock.
- *
- * To see an example of interaction of all these issues, take a look at the
- * lov_cl.c:lov_lock_enqueue() function. It is called as a part of
- * cl_enqueue_try(), and tries to advance top-lock to ENQUEUED state, by
- * advancing state-machines of its sub-locks (lov_lock_enqueue_one()). Note
- * also, that it uses trylock to grab sub-lock mutex to avoid dead-lock. It
- * also has to handle CEF_ASYNC enqueue, when sub-locks enqueues have to be
- * done in parallel, rather than one after another (this is used for glimpse
- * locks, that cannot dead-lock).
+ * cl_lock is a cacheless data container for the requirements of locks to
+ * complete the IO. cl_lock is created before I/O starts and destroyed when the
+ * I/O is complete.
+ *
+ * cl_lock depends on LDLM lock to fulfill lock semantics. LDLM lock is attached
+ * to cl_lock at OSC layer. LDLM lock is still cacheable.
  *
  * INTERFACE AND USAGE
  *
- * struct cl_lock_operations provide a number of call-backs that are invoked
- * when events of interest occurs. Layers can intercept and handle glimpse,
- * blocking, cancel ASTs and a reception of the reply from the server.
+ * Two major methods are supported for cl_lock: clo_enqueue and clo_cancel.  A
+ * cl_lock is enqueued by cl_lock_request(), which will call clo_enqueue()
+ * methods for each layer to enqueue the lock. At the LOV layer, if a cl_lock
+ * consists of multiple sub cl_locks, each sub locks will be enqueued
+ * correspondingly. At OSC layer, the lock enqueue request will tend to reuse
+ * cached LDLM lock; otherwise a new LDLM lock will have to be requested from
+ * OST side.
  *
- * One important difference with the old client locking model is that new
- * client has a representation for the top-lock, whereas in the old code only
- * sub-locks existed as real data structures and file-level locks are
- * represented by "request sets" that are created and destroyed on each and
- * every lock creation.
+ * cl_lock_cancel() must be called to release a cl_lock after use. clo_cancel()
+ * method will be called for each layer to release the resource held by this
+ * lock. At OSC layer, the reference count of LDLM lock, which is held at
+ * clo_enqueue time, is released.
  *
- * Top-locks are cached, and can be found in the cache by the system calls. It
- * is possible that top-lock is in cache, but some of its sub-locks were
- * canceled and destroyed. In that case top-lock has to be enqueued again
- * before it can be used.
+ * LDLM lock can only be canceled if there is no cl_lock using it.

- *     - "non-try" functions that implement synchronous blocking interface on

- *     immediately, wait for lock state change.

- *     be advanced to the target state only when all layers voted that they
- *     are ready for this transition. "Try" functions call methods under lock
- *     mutex. If a layer had to release a mutex, it re-acquires it and returns

- s-Par Proc Entries
-This document describes the proc entries created by the Unisys s-Par modules.
-
-Support Module Entries
-These entries are provided primarily for debugging.
-
-/proc/uislib/info: This entry contains debugging information for the
-uislib module, including bus information and memory usage.
-
-/proc/visorchipset/controlvm: This directory contains debugging
-entries for the controlvm channel used by visorchipset.
-
-/proc/uislib/platform: This entry is used to display the platform
-number this node is in the system. For some guests, this may be
-invalid.
-
-/proc/visorchipset/chipsetready: This entry is written to by scripts
-to signify that any user level activity has been completed before the
-guest can be considered running and is shown as running in the s-Par
-UI.
-
-Device Entries
-These entries provide status of the devices shared by a service partition.
-
-/proc/uislib/vbus: this is a directory containing entries for each
-virtual bus. Each numbered sub-directory contains an info entry, which
-describes the devices that appear on that bus.
-
-/proc/uislib/cycles_before_wait: This entry is used to tune
-performance, by setting the number of cycles we wait before going idle
-when in polling mode. A longer time will reduce message latency but
-spend more processing time polling.
-
-/proc/uislib/smart_wakeup: This entry is used to tune performance, by
-enabling or disabling smart wakeup.
-
-/proc/virthba/info: This entry contains debugging information for the
-virthba module, including interrupt information and memory usage.
-
-/proc/virthba/enable_ints: This entry controls interrupt use by the
-virthba module. Writing a 0 to this entry will disable interrupts.
-
-/proc/virtnic/info: This entry contains debugging information for the
-virtnic module, including interrupt information, send and receive
-counts, and other device information.
-
-/proc/virtnic/ethX: This is a directory containing entries for each
-virtual NIC. Each named subdirectory contains two entries,
-clientstring and zone.
-
-/proc/virtpci/info: This entry contains debugging information for the
-virtpci module, including virtual PCI bus information and device
-locations.
-
-/proc/virtnic/enable_ints: This entry controls interrupt use by the
-virtnic module. Writing a 0 to this entry will disable interrupts.
-
-Visorconinclient, visordiag, visornoop, visorserialclient, and
-visorvideoclient Entries
-
-The entries in proc for these modules all follow the same
-pattern. Each module has its own proc directory with the same name,
-e.g. visordiag presents a /proc/visordiag directory. Inside of the
-module's directory are a device directory, which contains one numbered
-directory for each device provided by that module. Each device has a
-diag entry that presents the device number and visorbus name for that
-device. The module directory also has a driver/diag entry, which
-reports the corresponding s-Par version number of the driver.
-
-Automated Installation Entries
-
-These entries are used to pass information between the s-Par platform
-and the Linux-based installation and recovery tool. These values are
-read/write, however, the guest can only reset them to 0, or report an
-error status through the installer entry. The values are only set via
-s-Par's firmware interface, to help prevent accidentally booting into
-the tool.
-
-/proc/visorchipset/boottotool: This entry instructs s-Par that the
-next reboot will launch the installation and recovery tool. If set to
-0, the next boot will happen according to the UEFI boot manager
-settings.
-
-/proc/visorchipset/toolaction: This entry indicates the installation
-and recovery tool mode requested for the next boot.
-
-/proc/visorchipset/installer: this entry is used by the installation
-and recovery tool to pass status and result information back to the
-s-Par firmware.
-
-/proc/visorchipset/partition: This directory contains the guest
-partition configuration data for each virtual bus, for use during
-installation and at runtime for s-Par service partitions.

+
+	  USB Type-C Connector System Software Interface (UCSI) is a
+	  specification for an interface that allows the Operating System to
+	  control the USB Type-C ports on a system. Things the need controlling
+	  include the USB Data Role (host or device), and when USB Power
+	  Delivery is supported, the Power Role (source or sink). With USB
+	  Type-C connectors, when two dual role capable devices are attached
+	  together, the data role is selected randomly. Therefore it is
+	  important to give the OS a way to select the role. Otherwise the user
+	  would have to unplug and replug in order in order to attempt to swap
+	  the data and power roles.
+
+	  The UCSI specification can be downloaded from:
+	  http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html
