Kalle Valo bdcd817079 Add ath6kl cleaned up driver
Last May we started working on cleaning up ath6kl driver which is
currently in staging. The work has happened in a separate
ath6kl-cleanup tree:

http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary

After over 1100 (!) patches we have now reached a state where I would
like to start discussing about pushing the driver to the wireless
trees and replacing the staging driver.

The driver is now a lot smaller and looks like a proper Linux driver.
The size of the driver (measured with simple wc -l) dropped from 49
kLOC to 18 kLOC and the number of the .c and .h files dropped from 107
to 22. Most importantly the number of subdirectories reduced from 26
to zero :)

There are two remaining checkpatch warnings in the driver which we
decided to omit for now:

drivers/net/wireless/ath/ath6kl/debug.c:31:
  WARNING: printk() should include KERN_ facility level
drivers/net/wireless/ath/ath6kl/sdio.c:527:
  WARNING: msleep < 20ms can sleep for up to 20ms;
  see Documentation/timers/timers-howto.txt

The driver has endian annotations for all the hardware specific
structures and there are no sparse errors. Unfortunately I don't have
any big endian hardware to test that right now.

We have been testing the driver both on x86 and arm platforms. The
code is also compiled with sparc and parisc cross compilers.

Notable missing features compared to the current staging driver are:

o HCI over SDIO support
o nl80211 testmode
o firmware logging
o suspend support

Testmode, firmware logging and suspend support will be added soon. HCI
over SDIO support will be more difficult as the HCI driver needs to
share code with the wifi driver. This is something we need to research
more.

Also I want to point out the changes I did for signed endian support.
As I wasn't able to find any support for signed endian annotations I
decided to follow what NTFS has done and added my own. Grep for sle16
and sle32, especially from wmi.h.

Various people have been working on the cleanup, the hall of
fame based on number of patches is:

Bruno Randolf 1bba5b7329 ath: Copy key cache management functions from ath9k to ath
Copied the key cache management functions from ath9k (common.c and hw.c) to
ath/key.c so we can use them from ath5k, later.

Minor changes have been made:
 - renamed ath9k_* to ath_*
 - replaced ah->caps.keycache_size with common->keymax
 - removed ATH9K_IS_MIC_ENABLED since it is always true.
 - the AR_PCU_MIC_NEW_LOC_ENA flag is replaced with (splitmic == 0).

Luis R. Rodriguez 7322fd1929 ath9k: move hw code to its own module
hw code for Atheros 802.11n hardware is commmon between
different chipsets. This moves this code into a separate
module, the next expected user of this code will be
the ath9k_htc module.

The ath9k/ dir is now selected by ATH9K_HW, an option which
gets selected by either ath9k or ath9k_htc, but remains
invisible for user menuconfig configuration. If either
ath9k or ath9k_htc will be compiled into the kernel
ath9k_hw will also be compiled in.

Luis R. Rodriguez c46917bb53 atheros: add common debug printing
ath9k uses this for now, ath9k_htc is expected to re-use this
as well. We lave ath5k as is, but it certainly can also be
converted later.

The ath9k module parameter and debugfs entry is kept.

Bob Copeland 3a702e49c0 atheros: introduce ath module containing common ath5k/ath9k/ar9170 code
This change creates a new module, ath.ko, which includes code that can
be shared between ath5k, ath9k and ar9170. For now, extract most of the ath9k
regulatory code so it can also be used in ath5k.
