#1226205 — [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.

Looks Good To Me, and has Sascha's ACKs, so merged patches
1, 2, 3, 4 to the pinctrl tree. Please merge the AT91 DT things into
the AT91 tree.

Great!

So patch 5 is included in at91-4.4-defconfig branch.
patches 6 and 7 queued in at91-4.4-dt branch.
They are included in at91-next that is merged in linux-next and will
both take the arm-soc path later in the cycle.

Thanks, bye,
