[PATCH 0/4] Introduce the Atmel PTC subsystem

[Ludovic Desroches]

Hi,

The Atmel Peripheral touch controller subsystem offers built-in hardware for
capacitive touch measurment 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.
