* Freescale MPC512x/MPC8xxx/Layerscape GPIO controller Required properties: - compatible : Should be "fsl,-gpio" The following s are known to be supported: mpc5121, mpc5125, mpc8349, mpc8572, mpc8610, pq3, qoriq. - reg : Address and length of the register set for the device - interrupts : Should be the port interrupt shared by all 32 pins. - #gpio-cells : Should be two. The first cell is the pin number and the second cell is used to specify the gpio polarity: 0 = active high 1 = active low Optional properties: - little-endian : GPIO registers are used as little endian. If not present registers are used as big endian by default. Example: gpio0: gpio@1100 { compatible = "fsl,mpc5125-gpio"; #gpio-cells = <2>; reg = <0x1100 0x080>; interrupts = <78 0x8>; status = "okay"; };
