Several fixes based on customer feedback:
* WHO_AM_I value has changed since preliminary parts used for initial
testing;
* Output of le16_to_cpu must be saved to memory before shifting to
preserve sign;
* Initial data rate was not extracted from data control register init.
This was causing the initial data rate to be set to maximum until
it was changed. To fix this problem, it made more sense to specify
initial data rate and extract the register mask from that.

Some displays from AUO have a so called in-cell touchscreen, meaning it
is built directly into the display unit.
Touchdata is gathered through PIXCIR Tango-ICs and processed in an
Atmel ATmega168P with custom firmware. Communication between the host
system and ATmega is done via I2C.
Devices using this touch solution include the Dell Streak5 and the family
of Qisda ebook readers.
The driver reports single- and multi-touch events including touch area
values.

The previous algorithm requires that kpd_trigger_delay_us be set to
1/32 of the preferred trigger delay. The new algorithm allows setting
kpd_trigger_delay_us to the preferred trigger delay directly.
The actual delay can only be one of the eight levels: 2 sec, 1 sec,
1/2 sec, 1/4 sec, 1/8 sec, 1/16 sec, 1/32 sec, and 1/64 sec. The valid
range of kpd_trigger_delay_us is 1/64 second to 2 seconds. A value
within the valid range will be rounded down to the closest level. Any
value outside the valid range will be rejected.
Update board files for targets that use this driver accordingly.

There exist tilt switches that simply report their tilt-state via
some gpios. The number and orientation of their axes can vary
depending on the switch used and the build of the device. Also two
or more one-axis switches could be combined to provide multi-dimensional
orientation.
One example of a device using such a switch is the family of Qisda
ebook readers, where the switch provides information about the
landscape / portrait orientation of the device. The example in
Documentation/input/gpio-tilt.txt documents exactly this one-axis
device.

The ADP5585 family keypad decoder and IO expander is similar to the ADP5589,
however it features less IO pins, and lacks hardware assisted key-lock

the event codes and bit organization within the port related registers.
