[RFC PATCH 0/3] New Atmel PIO4 pinctrl/gpio driver

[Ludovic Desroches]

Hi,

Following our discussion, I send an RFC version of my driver. RFC because it is
not totally achieved, some cleanup and feature addition is needed.

At least, we could discuss about the 'core' part. I have used the pinmux
property as Mediatek driver. Patch 3 is the internal dt files we are using.

Thanks for your reviews.
