[PATCH 0/5] msg2638: Add support for msg2138 and key events

This series:
- moves max fingers number and irqhandler settings in a struct
- adds support for msg2138 touchscreen
- adds support for buttons, which were only seen with msg2138 as of yet

Big thanks to Stephan Gerhold [off-list ref] for the help with
deciphering the downstream driver [1] and writing clean and working code.
