Subject: wl18xx: use module_platform_driver

the driver's init and exit routines can be implemented with the
module_platform_driver, as the init and exit code is same as
that of the module_platform_driver

Subject: wl12xx: use module_platform_driver

Use a module_platform_driver declaration instead of replicating the
init and exit functions in the driver.

Based on the patch for wl18xx by Devendra Naga.

Subject: wlcore: consider single fw case

When a single fw is being used for both single-role
and multi-role cases (e.g. 18xx), wl->mr_fw_name is
NULL, which results in NULL dereference while trying
to load the multi-role fw.

In this case, always use the single-role fw, and avoid
redundant fw switch by checking for this case in
wl12xx_need_fw_change() as well.

Subject: wlcore: Prevent interaction with HW after recovery is queued

When a function requests to recover, it would normally abort and will
not send any additional commands to the HW. However, other threads may
not be aware of the failure and could try to communicate with the HW
after a recovery was queued, but before the recovery work began.

Fix this by introducing an intermediate state which is set when recovery
is queued, and modify all state checks accordingly.

Subject: wlcore: tx_flush - optimize flow and force Tx during the flush

Force Tx during the flush if there are packets pending in the driver.
This actually solves a bug where we would get called from the mac80211
wq context, which would prevent tx_work from getting queued, even when
the mutex is unlocked.

Don't stop the queues needlessly if there's nothing to flush. Use a
larger delay when sleeping to give the driver a chance to flush and
avoid cpu busy looping. Re-arrange the loop so the last iteration is
not wasted.

Subject: wlcore: configure wowlan regardless of wakeup conditions

wowlan filters should be configured in any case in suspend/resume.
This shouldn't be dependent on whether wakeup conditions are the
same for suspend and resume states. Only the FW command to
reconfigure wakeup conditions should be avoided in such a case.

Subject: wlcore: resume() only if sta is associated

mac80211's resume() callback might get called even if
the sta is not associated (but only up). The
resume sequence in this case results in configuring
the wake-up conditions of a non-started role, which
causes fw assertion.

Fix it by bailing out if the STA is not connected
(like we do on suspend()).

Subject: wl18xx: number_of_assembled_ant5 indicates if A band is enabled

Use number_of_assembled_ant5 phy param to indicate if A band is enabled:
if number_of_assembled_ant5 != 0 then it is enabled otherwise it is
disabled.

This aligns with phy implementation that uses this param both to indicate
if band is active and the number of antennas.

This parameter replaces enable_11a module param that was removed.

User-Space applications can use wlconf and/or INI files to disable A band
using this parameter.

Subject: wlcore: Don't recover during boot

While recursive recovery is avoided during shutdown, a new recovery may
be queued when the FW boots. The recovery work will then try to stop an
already stopped hardware, which will most likely result in a kernel
panic.

Fix this by verifying that wl->state is on before queueing a new
recovery.

Subject: wlcore: invalidate keep-alive template on disconnection

Previously, invalidation of the keep-alive template was
done when going idle. However, while removing the
idle-handling we didn't move the keep-alive template
invalidation to another place.

This finally resulted in fw error when trying to use
the keep-alive template by another role.

(Note that we still have an error here - each role
should have its unique keep-alive template id, while
currently they all use CMD_TEMPL_KLV_IDX_NULL_DATA (0).
This only works now because we don't support concurrent
connected stations yet)

Currently, all the (station) roles use the same
keep-alive template id (0). However, the klv
template ids shouldn't be shared by different
roles.

Implement a simple klv_templates bitmap, and let
each role allocate its own klv template id on
role initialization.

[Arik - remove invalidation of KLV template when getting into "idle".
This is already handled in unjoin]

Subject: wlcore: Allow memory access when the FW crashes

When the no_recovery flag is used, the recovery work will not restart
the FW and the state will not be set to 'on'. To enable post-mortem
analysis, allow memory access in the 'restarting' state.

Also, since the FW might not be operational, don't fail the read/write
operations if elp_wakeup fails.

Subject: wlcore: Load the NVS file asynchronously

The NVS file is loaded by the device's probe callback with the help of
request_firmware(). Since request_firmware() relies on udevd, the
modules cannot be loaded before hotplug events are handled.

Fix this by loading the NVS file asynchronously and continue
initialization only after the firmware request is over.

Subject: wlcore: decrease elp timeout

The current elp timeout (the same as the dynamic
ps timeout - 1500ms) is too high. Usually,
wl1271_ps_elp_sleep() get called right after tx/rx,
which is fine, but some command might get sent
even when there is no traffic (e.g. ht changes
triggered by beacon frames), and leaving the
device awake for 1500ms in this case is redundant.

Use a timeout of 30ms.
The fw won't enter elp anyway before the dynamic-ps
timeout was expired as well (and it entered ps
successfully).

Subject: wlcore: protect wlcore_op_set_key with mutex

wlcore_op_set_key() calls wl18xx_set_key(),
which in turn executes some of his function
calls without acquiring wl->mutex and making
sure the fw is awake.

Adding mutex_lock()/ps_elp_wakeup() calls is
not enough, as wl18xx_set_key() calls
wl1271_tx_flush() which can't be called while
the mutex is taken.

Add the required calls to wlcore_op_set_key,
but limit the queues_stop and flushing
to the only encryption types in which
a spare block might be needed (GEM and TKIP).

Subject: ath9k: Fix rx filtering issue for older chips

We need to have the promiscuous mode enabled for older
chipsets so that the olderchips hardware does not
filters out some valid/necessary frames that need
to be sent to mac80211. Fix this by enabling promiscus
mode for all the chipsets whose macversion <= AR9160
chipsets. This should fix
https://bugzilla.kernel.org/show_bug.cgi?id=45591

shafi: made the fix generic by having the frame filtering
disabled for chipsets older than AR9280.

Subject: mwifiex: send firmware initialization commands synchronously

The driver will send some commands to firmware during the
initialization. Currently these commands are sent asynchronously,
which means that we firstly insert all of them to a pre-allocated
command queue, and then start to process them one by one. The
command queue will soon be exhausted if we keep adding new
initialization commands.

This issue can be resolved by sending initialization commands
synchronously because each command is consumed and the buffer is
recycled before queuing next command.

Subject: mwifiex: add inactivity deauth support for ap

The firmware has support for this feature, so we offload it to
firmware. In start_ap, driver passes the inactivity timeout
value to firmware via TLVs and firmware will report STA_DEAUTH
event to driver when inactivity timer is fired.

Subject: ath9k: Fix chainmask selection for AR9462

Force chain 1 to be used for CCK rates since the target power
table stored in EEPROM is too high to transmit with both chains.
This is needed to avoid regulatory violation.

The problem is fixed by making certain that the ucode pointer is not NULL
before deregistering the driver in mac80211.

Subject: brcmfmac: use wait_event_timeout for fw control packets over usb.

firmware control packets over usb are async acked. This is
awaited for by using interruptible wait. This can be
interrupted by signal which results in undesirable behavior.
Instead wait_event_timeout is used.

Subject: brcmfmac: use brcmf_cfg80211_priv to interface with wl_cfg80211 code

The low-level driver part interfaces with wl_cfg80211 part using
brcmf_cfg80211_dev structure as handle. As brcmf_cfg80211_priv
is defined in interface it is more efficient to use that as handle
in function calls.

Subject: brcmfmac: rename structure brcmf_cfg80211_priv

Renamed structure to brcmf_cfg80211_info as it is not really a
private structure since it is exposed in header file.

Subject: brcmfmac: remove brcmf_read_prof() function

The function brcmf_read_prof() provided access to fields
with brcmf_cfg80211_profile structure using a field id,
but the calling function can easily access that structure
directly. This patch removes the function.

Subject: ath9k_hw: Handle AR_INTR_SYNC_HOST1_(FATAL|PERR) on AR9003

Interrupts with the sync_cause AR_INTR_SYNC_HOST1_FATAL and
AR_INTR_SYNC_HOST1_PERR have to be handled using a chip reset. Otherwise a
interrupt storm with unhandled interrupts will cause a hang or crash of the
machine.

Subject: ath9k: Fix BTCOEX weight initialization

The WLAN/BT weights have to set correctly before BTCOEX
is initialized. Currently, this is not done for all chips
in the AR9003 family. This patch fixes this issue by setting
the weights in the init path. While at it, rename ar9462_wlan_weights
to mci_wlan_weights since it is common to both AR9462 and AR9565.
