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

* 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:

sound@fffa0000 {

       compatible = "atmel,at91sam9263-ac97c";

       pinctrl-names = "default";

       pinctrl-0 = <&pinctrl_ac97>;

       reg = <0xfffa0000 0x4000>;

       interrupts = <18 IRQ_TYPE_LEVEL_HIGH 5>;



       ac97-gpios = <&pioB 0 0 &pioB 2 0 &pioC 29 GPIO_ACTIVE_LOW>;

};
