+* Freescale MPC512x/MPC8xxx GPIO controller
+
+Required properties:
+- compatible : Should be "fsl,<soc>-gpio"
+ The following <soc>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
+
+Example:
+
+gpio0: gpio@1100 {
+ compatible = "fsl,mpc5125-gpio";
+ #gpio-cells = <2>;
+ reg = <0x1100 0x080>;
+ interrupts = <78 0x8>;
+ status = "okay";
+};
