[PATCH v3 16/49] Input: atmel_mxt_ts - allow specification of firmware file name

[Jiada Wang]

From: Nick Dyer <nick.dyer@itdev.co.uk>

On platforms which have multiple device instances using this driver, the
firmware may be different on each device. This patch makes the user give
the name of the firmware file when flashing.

This also prevents accidental triggering of the firmware load process.

[PATCH v3 17/49] Input: atmel_mxt_ts - handle cfg filename via pdata/sysfs

[Jiada Wang]

From: Nick Dyer <nick.dyer@itdev.co.uk>

There may be multiple maXTouch chips on a single device which will require
different configuration files. Add a platform data value for the
configuration filename.

Add sysfs entry to write configuration file if the platform data is not
set.

Split out the object initialisation code from mxt_initialize() into
mxt_configure_objects() to allow this.

[PATCH v3 18/49] Input: atmel_mxt_ts - allow input name to be specified in platform data

From: Nick Dyer <nick.dyer@itdev.co.uk>

Android systems identify the input device and map to IDC file by using the
input device name. To avoid unnecessary deltas to the driver file, allow
this to be set from the platform data.
