The size of the eeprom data is 1088 bytes for AR9485. But
a sanity check is done against 4K which would result in a
'potential read past the end of the buffer' smatch complaint.

Introduce a helper function to get the EEPROM mode from channel and remove
multiple similar switch statements. Also since it's now easy to get the EEPROM
mode from the channel, use them inside the functions which need it, instead of
passing a redundant ee_mode parameter.

Add a new variable to keep track of the currently configured tx power. Before
max_pwr was re-used for keeping the maximum allowed power as well as the
current configuration. Doing a min() on it allows you to lower the txpower, but
how would you be able to make it higher again?
This patch fixes that by adding a new variable ah_cur_pwr which is used instead
of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check
if we are within the limits.
Another problem fixed by this patch is that it avoids setting a zero txpower
when things are initialized first and the current power is not yet set.

ath9k supports its own set of virtual wiphys, and it uses
the mac80211 idle notifications to know when a device needs
to be idle or not. We recently changed ath9k to force idle
on driver stop() and on resume but forgot to take into account
ath9k's own virtual wiphy idle states. These are used internally
by ath9k to check if the device's radio should be powered down
on each idle call. Without this change its possible that the
device could have been forced off but the virtual wiphy idle
was left on.

The commit "ath9k_hw: warn if we cannot change the power to the chip"
introduced a new warning to indicate chip powerup failures, but this
is not required for devices that have been removed. Handle USB device
removal properly by checking for unplugged status.
For PCI devices, this warning will still be seen when the card is pulled
out, not sure how to check for card removal.

Apart from the regular AM18x/DA850/OMAP-L138 SoC operating
at 300MHz, these SoCs have variants that can operate at a
maximum of 456MHz. Variants at 408Mhz and 375 Mhz are available
as well.
Not all silicon is qualified to run at higher speeds and
unfortunately the maximum speed the chip can support can only
be determined from the label on the package (not software
readable).
The EVM hardware for all these variants is the same (except
for the actual SoC populated).
U-Boot on the EVM sets up ATAG_REVISION to inform the OS
regarding the speed grade supported by the silicon. We use
this information to pass on the speed grade information to
the SoC code.

AM18x/DA850/OMAP-L138 SoCs have variants that can operate
at a maximum of 456 MHz at 1.3V operating point. Also the
1.2V operating point has a variant that can support a maximum
of 375 MHz.
This patch adds three new OPPs (456 MHz, 408 MHz and 372 MHz)
to the list of DA850 OPPs.
Not all silicon is qualified to run at higher speeds and
unfortunately the maximum speed the chip can support can only
be determined from the label on the package (not software
readable).
Because of this, we depend on the maximum speed grade information
to be provided to us in some board specific way. The board informs
the maximum speed grade information by setting the da850_max_speed
variable.

This patch adds a pca953x platform device for the tca6416 found on the evm
baseboard. The tca6416 is a GPIO expander, also found on the UI board at a
separate I2C address. The pins of the baseboard IO expander are connected to
software reset, deep sleep enable, test points, a push button, DIP switches and
LEDs.
Add support for the push button, DIP switches and LEDs and test points (as
free GPIOs). The reset and deep sleep enable connections are reserved by the
setup routine so that userspace can't toggle those lines.
The existing tca6416-keypad driver was not employed because there was no
apararent way to register the LEDs connected to gpio's on the tca6416 while
simultaneously registering the tca6416-keypad instance.

This patch adds EV_KEYs for each of the 8 pushbuttons on the UI board via a
gpio-key device.
The expander is a tca6416; it controls the SEL_{A,B,C} lines which enable and
disable the peripherals found on the UI board in addition to the 8 pushbuttons
mentioned above. The reason the existing tca6416-keypad driver is not employed
is because there was no aparent way to keep the gpio lines used as
SEL_{A,B,C} registered while simultaneously registering the pushbuttons as a
tca6416-keypad instance.
Some experimentation with the polling interval was performed; we were searching
for the largest polling interval that did not affect the feel of the
responsiveness of the buttons. It is very subjective but 200ms seems to be a
good value that accepts firm pushes but rejects very light ones. The key values
assigned to the buttons were arbitrarily chosen to be F1-F8.

sfq_walk() runs without qdisc lock. By the time it selects a non empty
hash slot and sfq_dump_class_stats() is run (with lock held), slot might
have been freed : We then access q->slots[SFQ_EMPTY_SLOT], out of
bounds, and crash in slot_queue_walk()
On previous kernels, bug is here but out of bounds qs[SFQ_DEPTH] and
allot[SFQ_DEPTH] are located in struct sfq_sched_data, so no illegal
memory access happens, only possibly wrong data reported to user.
Also, slot_dequeue_tail() should make sure slot skb chain is correctly
terminated, or sfq_dump_class_stats() can access freed skbs.

iwlwifi and other drivers like to blink their LED
based on throughput. Implement this generically in
mac80211, based on a throughput table the driver
specifies. That way, drivers can set the blink
frequencies depending on their desired behaviour
and max throughput.
All the drivers need to do is provide an LED class
device, best with blink hardware offload.

The throughput trigger will require doing LED
classdev/trigger handling before register_hw(),
so drivers should have access to the trigger
names before it. If trigger registration fails,
this will still make the trigger name available,
but that's not a big problem since the default
trigger will the simply not be found.

Commit 60d24ee "Added video data to support tvout on rx51" added code that
tries to assign gpio 40 as OMAP DSS reset_gpio for tvout. This is wrong
since this gpio has nothing to do with OMAP DSS but it is used to control
one switch that selects is the audio jack connected to tvout or audio
circuitry.
This switch is already supported by the RX51 ASoC driver so there is no need
to control it elsewhere. Switch is contolled with ALSA control
'Jack Function' and tvout can be selected with following example:
amixer -D hw:0 set 'Jack Function' 'TV-OUT'
