Subject: [PATCH 01/48] wl12xx: set do_join on BSS_CHANGED_ASSOC

wl12xx sets the do_join flag (which later starts the
sta role) when the bssid was changed and the sta is
associated. However, this no longer happens after
the "mac80211: remove spurious BSSID change flag"
patch.

Fix it by setting the do_join flag on BSS_CHANGED_ASSOC
(for IBSS, do_join is already set on BSS_CHANGED_IBSS)

The iteration on the wlvif list in wl1271_op_resume/suspend was
perfomed before locking wl->mutex which would lead to a kernel
panic in case a recovery was queued at the same time
and would delete the wlvifs from the list.

wlvif->probereq is zeroed when adding an interface but

This would lead to a mem leak on every recovery.

Subject: [PATCH 07/48] wl12xx: adaptive sched scan dwell times

Set the dwell times for sched scan according to the number
of probe requests which are going to be transmitted.
This should fix the too short dwell time problem which
prevented some of the probe requests from being transmitted
in cases of high number of SSIDs (10+) to be actively sched scanned.
However, in the common case of having up to 1-2 SSIDs that
require active scan, the dwell time would be kept to a minimum
which should conserve power. This is important as sched scan
also runs periodically while the host is suspended and there's
great importance to keep power consumption as low as possible.

Subject: [PATCH 08/48] wl12xx: increase scan timeout to 30s

In certain scenarios involving sched scan + normal scan + COEX
scan could take longer than 10s and this triggers a recovery
where it shouldn't. Increase the timeout to avoid that.

Subject: [PATCH 09/48] wireless/wl12xx/wl1251: move TI WLAN modules to a
 common ti subdirectory

Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti
directory.  Add a TI WLAN Kconfig option and Makefile to support this
change.

Subject: [PATCH 10/48] wl12xx/wlcore: rename wl12xx to wlcore

Rename the wl12xx driver directory to wlcore as an initial step
towards the split of the driver into wlcore and wl12xx.  We just
rename the directory first to keep git blame happy.

From b2ba99ff327f43684993c47a0f34bfa48f2ac210 Mon Sep 17 00:00:00 2001
From: Luciano Coelho <coelho@ti.com>
Date: Sun, 20 Nov 2011 23:32:10 +0200
Subject: [PATCH 11/48] wl12xx/wlcore: spin out the wl12xx probe from wlcore to
 a new wl12xx

Create a new small wl12xx module that only contains the probe
functions and depends entirely on wlcore otherwise.

Subject: [PATCH 12/48] wl12xx/wlcore: initial split of probe

We need to set some parameters (eg. partition and register tables)
during probe of the lower driver, so split the probe function, leaving
most of it in wlcore, but moving the hw struct allocation to the lower
driver.

Subject: [PATCH 13/48] wl12xx/wlcore: move wl1271 struct to wlcore and add ops

In order to add chip-specific operations and prepare for future
elements that need to be set by the lower driver, move the wl1271
structure to the wlcore.h file and add an empty placeholder for the
operations structure.

From 25a43d78eb63281294793fdaab6108bef81d7648 Mon Sep 17 00:00:00 2001
From: Luciano Coelho <coelho@ti.com>
Date: Mon, 21 Nov 2011 20:37:14 +0200
Subject: [PATCH 14/48] wlcore/wl12xx: implement chip-specific partition tables

Add partition tables to wlcore, move and reorganize partition setting
functions.  Move wl12xx partition table to use the wlcore partition
table instead.

Subject: [PATCH 15/48] wlcore/wl12xx: implement chip-specific register tables

Add register tables support in wlcore, add some new IO functions to
read and write to chip-specific register and data addresses.  Move
some common register values from wl12xx to wlcore and add the
registers table to wl12xx.

From 6f7dd16cb125468a5393861c22fbecfb52dd9653 Mon Sep 17 00:00:00 2001
From: Luciano Coelho <coelho@ti.com>
Date: Tue, 29 Nov 2011 16:27:31 +0200
Subject: [PATCH 16/48] wlcore/wl12xx: add chip-specific identify chip
 operation

Move the code that identifies the chip ID and selects the appropriate
firmware to an operation implemented by the lower driver.  Also move
the quirks definitions into wlcore.h and rename to WLCORE_QUIRK_*.

Subject: [PATCH 17/48] wlcore/wl12xx: move get_pg_ver to the lower driver

The PG version depends on the actual hardware.  This commit moves the
code used to read the PG version to the lower driver, by adding the
get_pg_ver hardware operation.

Subject: [PATCH 18/48] wlcore/wl12xx: move top initialization to wl12xx

The top registers initialization is very specific to the actual
hardware used, even the way in which we read from and write to the top
registers varies from chip to chip.  This patch moves all top
registers initialization to wl12xx.  Also add a boot op for the wlcore
module to call at the right time and a few callbacks with the common
called to be called from the lower drivers boot operations.

Subject: [PATCH 19/48] wlcore/wl12xx: move MAC address reading operation to
 lower driver

Different chip families have the factory MAC address written in
different places.  Add a new hardware operation to read the MAC
address, if available.

Subject: [PATCH 21/48] wlcore/wl12xx: add quirk for legacy NVS support

Instead of checking the chip ID directly in the wlcore code to decide
whether to use the new or the old NVS format, we now use a quirk that
should be set by the low level driver to say that it needs to use the
old format.

Subject: [PATCH 22/48] wlcore: remove some unnecessary event mailbox address
 reads

We were reading the even mailbox address three times, which was
completely unnecessary and complicated things regarding partition
selection.  Remove the unnecessry reads and set the address for
mailbox 1 and 2 after the first read.

Subject: [PATCH 23/48] wlcore: add quirk to disable ELP

ELP is a very complicated process in the firmware.  Due to its
complexity, in some early firmware revisions, the ELP feature is
disabled.  To support this cases, this patch adds a quirk that
disables ELP mode.

When ELP is not supported, do not attempt to enter ELP when requested by
the driver.

Subject: [PATCH 26/48] wlcore/wl12xx: change GEM Tx-spare blocks per-vif

The number of spare Tx blocks must be changed when the GEM cipher is
engaged. Track set_key() operations to see if this is the case and
change the Tx HW spare block count accordingly. Set the number of spare
blocks for each operating mode from the low level driver.

Subject: [PATCH 29/48] wlcore/wl12xx: add hw op for setting frame length in
 tx_hw_desc

Each chip family indicates the length of a frame to the HW differently.
This includes different padding, alignment and other fields in the HW Tx
descriptor.

Put all wl12xx specific code in a hw op.

Subject: [PATCH 30/48] wlcore/wl12xx: add global elements to convert hw-rates
 to standard rates

Rates reported by HW can be different between chip families. Make the
rate-to-idx translation tables private per family and use them in a
common translation function. Add a global element to help determine
which rates are HW HT-rates.

Subject: [PATCH 31/48] wlcore: introduce Rx block-size alignment HW quirk

For chip-families that support aligned buffers in the Rx side. The Rx
flow changes slightly for these chips.

Currently these modifications rely on a hard-coded block-size of 256.

Subject: [PATCH 32/48] wlcore/wl12xx: add hw op for getting rx buffer data
 alignment

An aligned data buffer is such where the Ethernet portion of the packet
starts on a 4-byte boundary. Some chip families support padding the Rx
data buffer to achieve such alignment, others rely on the host to perform
it.
Implement the HW op for getting alignment state in wl12xx. Add
support for HW-padded alignment in the Rx flow.

Subject: [PATCH 33/48] wlcore/wl12xx: add prepare_read hw op for Rx data

The only difference in the read_data operations is that some chips
need to prepare the data to be read before reading.  So instead of
having a mandatory read_data operation, we now have an option
prepare_data operation that only needs to be implemented for chips
that require it.

In the wl12xx lower driver, we only set the prepare_data operation for
wl127x chips.

Subject: [PATCH 34/48] wlcore/wl12xx: add hw op for getting rx packet data
 length

There is a difference in the way chip families report the length of data
in a single Rx packet. Abstract this into a HW op. Refactor the Rx data
handling function to allocate the correct size for the data, and avoid
trimming the skb.

Subject: [PATCH 35/48] wlcore/wl12xx: split Tx completion to immediate/delayed

One chip family employs immediate Tx completion, where knowledge of
completed packets is given as part of the FW status. Another is only
notified of Tx completion via the FW status, and has to read the
completion status of the packets from a different location.

Implement the wl12xx tx completion as a delayed Tx completion.

Subject: [PATCH 36/48] wlcore/wl12xx: turn no-Tx-align quirk into Tx-align

Inverting the quirk flag to indicate Tx-alignment. This aligns it with
the similar Rx-side quirk.

The call to wl1271_set_block_size() decides whether SDIO block size
alignment can be used or not.  In case we're using SPI, we can't use
the block size alignment, so the function returns false.  So we set
the quirk when wl1271_set_block_size() returns true and let the wl12xx
lower driver unset the bit for wl127x (since it doesn't support this
quirk).

Subject: [PATCH 39/48] wlcore/wl12xx: expand functionality of cmd_trigger HW
 op

Change the cmd_trigger op to include the write of the command buffer.

Also, instead of letting the lower driver access the cmd_box_addr element
directly, we now pass the address in the trigger_cmd operation, so it
doesn't have to be exported.

Subject: [PATCH 40/48] wlcore/wl12xx: move runtime configuration struct to the
 lower driver

The configuration parameters vary with different chip families.  Some
of the parameters used only by some chip families, others should have
different value depending on the family.  Thus move the configuration
values from wlcore to wl12xx.

Subject: [PATCH 41/48] wlcore/wl12xx: move extended radio configuration
 parameters to wl12xx

The extended radio configuration parameters are only used by the
wl127x chipsets, which are handled by the wl12xx driver.  Move the rf
configuration settings from wlcore to wl12xx.

Subject: [PATCH 42/48] wlcore/wl12xx: use a single memory config and reset if
 using wl127x

Instead of having two memory configuration sets, one for wl127x and
one for wl128x, we can use only one which should be correctly set by
the lower driver.

The wl12xx driver now uses the wl128x memory config by default but
changes it when if it identifies the wl127x chips.

The max Rx aggregation subframes configured to FW must be the same
number given to the upper layers (mac80211). Derive both from the same
value, given in the conf struct.

Subject: [PATCH 46/48] wlcore/wl12xx: move identify firmware function to a
 lower driver op

Different chip families have different firmware versions, so we need
to identify the firmware to enable quirks, reject the used version
etc. in the lower drivers.  This commit turns the fw_ver_quirks
function into an identify_fw operation.
