[PATCH v2 0/5] Introduce the Atmel PTC subsystem

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.

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

- 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
