From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
Use CONFIG_ATH9K_TX99 to properly enclose the tx99 code
and make sure that it is not compiled as part of the driver
when it is not selected. Move the tx99 code to a new file tx99.c
and also add ATH9K_DEBUGFS as a dependency in Kconfig.
This reduces the module size on platforms like OpenWrt where
ATH9K_DEBUGFS is selected, but TX99 might be disabled.

From: Sujith Manoharan @ 2013-11-07 0:11 UTC (permalink / raw)
To: John Linville; +Cc: linux-wireless
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
The HW routines to set various WoW registers are present
in wow.c. For some reason, it has been compiled as part
of the main ath9k.ko module all this time, when it should
really be part of ath9k_hw.ko. This patch renames the file to
ar9003_wow.ko and adds it to ath9k_hw.ko.

Currently, the PLL is turned off for AR9485 when
switching to a low power state, but AR9485 has an issue
where the card will become unresponsive if left idle
for a long time without any traffic. To fix this,
force the PLL to always be on using a different initval
array, ar9485_1_1_pll_on_cdr_on_clkreq_disable_L1.

CUS227, which is an AR9340 based card used in Qualcomm's
Allplay platforms requires a custom TX gain array, based
on the index 7. Add suport for this.

While I don't have a problem with this, it's
more common to appoint a single person as a
"lead" maintainer.

Currently, there is no one to take on this role.
But the existing entries are outdated, so the official
