[PATCH 0/4] ath9k patches

[Sujith Manoharan]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

This series has a few RTC fixes. There are still two missing pieces:

* When a cold reset is performed, AR9100 requires the AHB/WMAC interface
  to be reset.
* AR955x requires an SoC RTC reset.

Both have to be done via the external_reset() platform interface.

Sujith Manoharan (4):
  ath9k: Remove ath9k_hw_gettsf32()
  ath9k: Add a delay between RTC reset/clear for AR9003
  ath9k: Fix RTC reset delay
  ath9k: Fix AR9330 external reset

[PATCH 0/4] ath9k patches

[Sujith Manoharan]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

QCA9531 is a 2x2 2.4 GHz SoC platform. This series starts adding support
for it.

Sujith Manoharan (4):
  ath9k: Add version/revision macros for QCA9531
  ath9k: Assign macVersion for QCA9531
  ath9k: Add QCA953x initvals
  ath9k: Initialize QCA953x INI arrays

[PATCH 0/4] ath9k patches

[Sujith Manoharan]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

With the introduction of channel context support, ath9k now supports
two types of operation, with separate paths for HW scan and SW scan.
The paths interleave in many places with code overlap and this makes the code
a bit hard to follow. This series begins to separate the two modes by making
the channel context code more self-contained. There is still lots to
be done, though.

Sujith Manoharan (4):
  ath9k: Add a config option for channel context
  ath9k: Move P2P functions to channel.c
  ath9k: Isolate P2P powersave routines
  ath9k: Isolate ath9k_use_chanctx module parameter

[PATCH 0/4] ath9k patches

[Sujith Manoharan]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

Third series cleaning up the channel context code. Most of the code
has been moved inside CONFIG_ATH9K_CHANNEL_CONTEXT. Since the normal
path also makes use of certain channel context specific variables,
they have been left unmodified - like 'cur_chan', 'cur_chandef' etc.

After this series, just 3 functions in channel.c are outside
CONFIG_ATH9K_CHANNEL_CONTEXT.

All the pending patches are in:

[PATCH 1/4] ath9k: Fix channel context variables in ath_softc

[Sujith Manoharan]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

chanctx_work and next_chan are required only when
CONFIG_ATH9K_CHANNEL_CONTEXT is enabled.

[PATCH 2/4] ath9k: Remove redundant ifdef

[Sujith Manoharan]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

This was introduced in an earlier patch to handle
a compilation warning, but since the channel context
code has been mostly isolated, this is not required now.
