Subject[PATCH 0/4] Input: cyapa - Add firmware update feature
Date
Add a feature to update trackpad firmware via request_firmware to cyapa.
The last patch in the series adds sysfs attributses useful for version
and product identification that a user mode utility will need to
keep track of the current firmware on the device.

This is used today on Chromebook systems with cypress trackpads:
Samsung Series 5 550 Chromebook
Acer C7
HP Pavilion 14
Samsung Chromebook (2012, ARM version)

[PATCH 1/4] Input: cyapa - Move common initialization to cyapa_detect
[PATCH 2/4] Input: cyapa - Firmware update via request firmware
[PATCH 3/4] Input: cyapa - Allow filename to be changed in update_fw
[PATCH 4/4] Input: cyapa - Add sysfs attrs for product_id and fw_version
