AR6003 is a single stream, SDIO based 802.11 chipset from
Atheros optimized for mobile and embedded devices. ath6kl is a
cfg80211 driver for AR6003 and supports both the station and
AP mode of operation.
Station mode supports 802.11 a/b/g/n with HT20 on 2.4/5GHz and
HT40 only on 5GHz. Some of the other features include WPA/WPA2,
WPS, WMM, WMM-PS, and BT coexistence. AP mode can be operated
only in b/g mode with support for a subset of features mentioned
above.
The driver supports cfg80211 but comes with its own set of
wext ioctls which have historically supported some of our
customers with features like BT 3.0 and AP mode of operation.
For further details, please refer to:
http://wireless.kernel.org/en/users/Drivers/ath6kl
The driver requires firmware that runs on the chip's network
processor. The majority of it is stored in ROM. The binaries
that are downloaded and executed from RAM are as follows:
1) Patch against the code in ROM for bug fixes and feature
enhancements.
2) Code to copy the data from the OTP region of the memory
into RAM.
3) Calibration file carrying board specific data.
The above files need to be present in the directory
'/lib/firmware/ath6k/AR6003/hw2.0/' for the driver to initialize
the chip upon enumeration. The files can be downloaded from the
link specified at the following location:
http://wireless.kernel.org/en/users/Drivers/ath6kl#Download
This driver is only provided in the interim while we work on
the mac80211 replacement, ath6k. Once the mac80211 driver
achieves feature parity with the ath6kl driver, the ath6kl will
be deprecated and removed from staging.

Currently, the user has to explicitly write a positive value to
initstate sysfs node before the device can be used. This event
triggers allocation of per-device metadata like memory pool,
table array and so on.
We do not pre-initialize all zram devices since the 'table' array,
mapping disk blocks to compressed chunks, takes considerable amount
of memory (8 bytes per page). So, pre-initializing all devices will
be quite wasteful if only few or none of the devices are actually
used.
This explicit device initialization from user is an odd requirement and
can be easily avoided. We now initialize the device when first write is
done to the device.

Creates per-device sysfs nodes in /sys/block/zram<id>/
Currently following stats are exported:
- disksize
- num_reads
- num_writes
- invalid_io
- zero_pages
- orig_data_size
- compr_data_size
- mem_used_total
By default, disksize is set to 0. So, to start using
a zram device, fist write a disksize value and then
initialize device by writing any positive value to
initstate. For example:
# initialize /dev/zram0 with 50MB disksize
echo 50*1024*1024 | bc > /sys/block/zram0/disksize
echo 1 > /sys/block/zram0/initstate
When done using a disk, issue reset to free its memory
by writing any positive value to reset node:
echo 1 > /sys/block/zram0/reset
This change also obviates the need for 'rzscontrol' utility.

the touch screen driver tries to find a range of free channels (which
are an array of bytes), by scanning for the "end of used channel" marker.
however it tries to be WAAAAY too smart and does 32 bit logic on 8 bit
quantities, and in the process completely gets it wrong
(repeatedly read the same register instead of incrementing in the loop,
assuming that if any of the 4 bytes in the 32 byte quantity is free,
all four are free, returning the channel number divided by 4 rather than
the actual first free channel number)
On the setting side, the same mistakes are made by and large; changed
this to just use the byte SCU write functions....
with these fixes we go from a completely non detected touchscreen to
something that appears to completely get detected.

In order to support multiple ST platform devices, a new symbol
'st_get_plat_device' earlier needed to be exported by the arch/XX/brd-XX.c
file which intends to add the ST platform device.
On removing this dependency, now inside ST driver maintain the array of
ST platform devices that would be registered.
As of now let id=0, as and when we end up having such platforms
where mutliple ST devices can exist, id would come from
protocol drivers (BT, FM and GPS) as to on which platform device
they want to register to.

Ew. Yeah, that doesn't look so hot like it is right now. The old lirc_imon
driver had chunk_num = buf[7], and made much more extensive use of
chunk_num. Simply removing chunk_num and using buf[7] should be fine.
