Hi,

The Atmel PIO4 controller has been introduced with SAMA5D2 chip family. This
drivers manages both pinmux/pinconf and gpio stuff. It is inspired by Mediatek
pinctrl driver.

Changes from v1:
- remove some unneeded gpio specific ops (gpio_request, gpio_free,
  gpio_request_enable, gpio_disable_free and gpio_set_direction).
- code styling fixes.
- add sama5d2 pin description and device pin muxing.
