Compatible=fsl,mpc8349-gpio

From FDTWiki

GPIO controllers on MPC8xxx SoCs. This is for the non-QE/CPM/GUTs GPIO controllers as found on some MPC8xxx parts including the MPC8349, MPC8572 and MPC8610.

Binds to

fsl,mpc8349-gpio

fsl,mpc8610-gpio

Required properties

compatible	string list	notes
#gpio-cells	1 cell	Must equal '2'. First cell is pin number. Second cell is flags (currently unused).
interrupts
reg
gpio-controller	empty	Marks the port as GPIO controller.

Example

gpio-controller nodes for an MPC8347 SoC:

       gpio1: gpio-controller@c00 {
               #gpio-cells = <2>;
               compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
               reg = <0xc00 0x100>;
               interrupts = <74 0x8>;
               interrupt-parent = <&ipic>;
               gpio-controller;
       };

       gpio2: gpio-controller@d00 {
               #gpio-cells = <2>;
               compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
               reg = <0xd00 0x100>;
               interrupts = <75 0x8>;
               interrupt-parent = <&ipic>;
               gpio-controller;
       };
