Subject: [PATCH v2 0/7] New Atmel PIO4 pinctrl/gpio driver

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.

Ludovic Desroches (7):
  pinctrl: introduce driver for Atmel PIO4 controller
  pinctrl: dt-binding: Add DT binding documentation for Atmel PIO4
  MAINTAINERS: Add an entry for pinctrl-at91-pio4
  ARM: at91/dt: sama5d2: add pio controller node
  ARM: at91/defconfig: sama5: add PIO4 controller support
  ARM: at91/dt: add sama5d2 pinmux
  ARM: at91/dt: sama5d2 Xplained: add device pin muxing
