+* Atmel PIO4 Controller
+
+The Atmel PIO4 controller is used to select the function of a pin and
to
+configure it.
+
+Required properties:
+- compatible: "atmel,sama5d2-pinctrl".
+- reg: base address and length of the PIO controller.
+- interrupts: interrupt outputs from the controller, one for each
bank.
+- interrupt-controller: mark the device node as an interrupt
controller.
+- #interrupt-cells: should be two.
+- gpio-controller: mark the device node as a gpio controller.
+- #gpio-cells: should be two.
+
+Please refer to ../gpio/gpio.txt and
../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of
the
+common pinctrl bindings used by client devices.
+
+Subnode format
+Each node (or subnode) will list the pins it needs and how to
configured these
... how to configure ...
Would you upstream this via linux kernel?

I'll pick this these days in a next branch for 2016.07, hopefully with a
lot more dt bindings.
Best Regards
Andreas
