Merge tag 'at91-dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into next/dt

Merge "at91: dt for 3.20 #2" from Nicolas Ferre:

Second DT batch for 3.20:
- correct some pin configuration for at91sam9x5ek
- add pioD on sama5d4 following a modification of pinctrl driver
- add more precise nand compatibility string for sama5d4
- audio modifications for wm8904 or ac97

* tag 'at91-dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91:
ARM: at91/dt: sam9263: Add ac97 device node

+* Atmel AC97 controller
+
+Required properties:
+  - compatible: "atmel,at91sam9263-ac97c"
+  - reg: Address and length of the register set for the device
+  - interrupts: Should contain AC97 interrupt
+  - ac97-gpios: Please refer to soc-ac97link.txt, only ac97-reset is used
+Optional properties:
+  - pinctrl-names, pinctrl-0: Please refer to pinctrl-bindings.txt
+
+Example:
