Subject: [PATCH 0/2] Input: add support for aXiom touchscreen controller
 using SPI or I2C

Summary of the added features:
 - Add input driver support for TouchNetix aXiom touchscreen controller
using either I2C or SPI.
 - Support ABS_MT touch reports in axiom_process_u41_report().
 - Support both polling and interrupt mode.
 - Add basic documentation and provide example device tree bindings.
 - Provide the basic structure to add firmware and config download in
the future via both I2C and SPI.

Many thanks,
Andrew
