627e7864f1 A local addition, not imported from ath9k. 
AR_PHY_CALMODE is explicitly reset on interface reset for other chipsets;
this commit also sets it for the AR9160.

52f81b679a Loading the NF CCA values may take longer than expected to occur. 
If it does, don't then try reprogramming the NF "cap" values (ie
what values are the "maximum" value the NF can be) - instead,
just leave the current CCA value as the NF cap.

This was inspired by some similar work from ath9k. It isn't
a 100% complete solution (as there may be some reason where a
high NF CCA/cap is written, causing the baseband to stop thinking it
is able to transmit, leading to stuck beacon and interface reset)
which I'll investigate and look at fixing in a later commit.

ccf98f5d9d Ensure that the correct rxchainmask is used when doing calibration in the 
AR5416 and later chipsets.

ath_hal_calibrateN() calls the HAL calibrateN function with rxchainmask=0x1.
This is not necessarily the case for AR5416 and later chipsets.

bc391cb2ce The Atheros AR71xx CPUs, when paired with the AR5212 parts, has a bug 
that generates a fatal bus trap.  Normally, the chips are setup to do
128 byte DMA bursts, but when on this CPU, they can only safely due
4-byte DMA bursts due to this bug.  Details of the exact nature of the
bug are sketchy, but some can be found at
https://forum.openwrt.org/viewtopic.php?pid=70060 on pages 4, 5 and 6.
There's a small performance penalty associated with this workaround,
so it is only enabled when needed on the Atheros AR71xx platforms.

Unfortunately, this condition is impossible to detect at runtime
without MIPS specific ifdefs.  Rather than cast an overly-broad net
like Linux/OpenWRT dues (which enables this workaround all the time on
MIPS32 platforms), we put this option in the kernel for just the
affected machines.  Sam didn't like this aspect of the patch when he
reviewed it, and I'd love to hear sane proposals on how to fix it :)

f3d3bf8731 Add support for the AR9285 chipset, which is found on many netbooks 
available today.

This card is a low power 802.11bgn that only does 11n rates up to MCS 7
(that's 65 Mbps in 20Mhz mode and 135 in 40Mhz mode).
802.11n is  not yet supported, but will be in the future.

The driver still has a problem regarding to the setting of txpower on
the card, so don't expect good performance yet. After fixing this
problem, an MFC is possible.

Special thanks to iXsystems and S Smirnov <tonve at yandex.ru> for help
with the purchase of a netbook with this card.
