Hi,

The Atmel Peripheral touch controller subsystem offers built-in hardware for
capacitive touch measurement on sensors that function as buttons, sliders and
wheels. It is available on SAMA5D2. Public documentation will be available
soon.

A firmware and a configuration file describing the topology and the parameters
of the sensor are loaded when probing the driver.

Changes:
- v3:
- fix MAINTAINERS entry
- v2:
- reorder patches to get the bindings documentation in first
- remove the header from the uapi since it may change in the future. Declare
only the few structures needed in the driver.
- add this driver to the sama5_defconfig
