* 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";
};
