Input: ad7879 - prevent invalid finger data reports
Considering following scenario - the touch is present on the screen
at the beginning of the last conversion sequence, but by the time
the last sequence is finished, the finger is lift off. The AD7879 data
available interrupt signals (DAV) completion, however some X,Y values
are not valid because the screen inputs were floating during the
acquisition.
The AD7877 acts differently here, since it only asserts DAV if the
touch is still present when the conversion sequence finished.
Based on the fact that this can only happen in the last sample of the
repeated conversion sequence, we simply skip the last (short glitches
are filtered by the AD7879 internal median and average filters).
This doesn't cause noticeable side effects, since the minimum conversion
interval is 9.44ms. We receive ~100 waypoint samples per second, so we
simply delay the result by 9.44ms.
We also reject samples where pressure is greater than pressure_max.

Input: ads7846 - switch to using threaded IRQ
Commit
9114337 introduces regulator operations in ads7846 touchscreen
driver. Among these operations, some are called while holding a
spinlock. On many platforms regulators reside on slow buses, such as
I2C/SPI and require sleep while accessing them.
The touchscreen itself is also a SPI device and currently relies on
asynchronous SPI access to avoid sleeping in interrupt context. Let's
switch to using threaded IRQ to be able to access SPI bus
synchronously (which simplifies driver a bit); it also allows safe
access to the regulators as well.
This has been tested on the ti_omap3530evm board:
1) using ts_lib after normal boot
2) using ts_lib after "#echo 1/0 > /sys/bus/spi/devices/spi0.1/disable"
3) using ts_lib after "#echo mem > /sys/power/state" and "wake up"

Input: add support for large scancodes
Several devices use a high number of bits for scancodes. One important
group is the Remote Controllers. Some new protocols like RC-6 define a
scancode space of 64 bits.
The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode
translation tables, but it is limited to up to 32 bits for scancode.
Also, if userspace wants to clean the existing table, replacing it by
a new one, it needs to run a loop calling the ioctls over the entire
sparse scancode space.
To solve those problems, this patch extends the ioctls to allow drivers
handle scancodes up to 32 bytes long (the length could be extended in
the future should such need arise) and allow userspace to query and set
scancode to keycode mappings not only by scancode but also by index.
Compatibility code were also added to handle the old format of
EVIO[CS]GKEYCODE ioctls.
Folded fixes by:
- Dan Carpenter: locking fixes for the original implementation
- Jarod Wilson: fix crash when setting keycode and wiring up get/set
handlers in original implementation.
- Dmitry Torokhov: rework to consolidate old and new scancode handling,
provide options to act either by index or scancode.

Staging: mrst-touchscreen - fix channel allocation
The touch screen driver tries to find a range of free channels (which

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....

something that appears to completely get detected.
