1 * Freescale MPC512x/MPC8xxx/QorIQ/Layerscape GPIO controller
4 - compatible : Should be "fsl,<soc>-gpio"
5 The following <soc>s are known to be supported:
6 mpc5121, mpc5125, mpc8349, mpc8572, mpc8610, pq3, qoriq,
7 ls1021a, ls1043a, ls2080a, ls1028a, ls1088a.
8 - reg : Address and length of the register set for the device
9 - interrupts : Should be the port interrupt shared by all 32 pins.
10 - #gpio-cells : Should be two. The first cell is the pin number and
11 the second cell is used to specify the gpio polarity:
16 - little-endian : GPIO registers are used as little endian. If not
17 present registers are used as big endian by default.
19 Example of gpio-controller node for a mpc5125 SoC:
22 compatible = "fsl,mpc5125-gpio";
25 interrupts = <78 0x8>;
28 Example of gpio-controller node for a ls2080a SoC:
31 compatible = "fsl,ls2080a-gpio", "fsl,qoriq-gpio";
32 reg = <0x0 0x2300000 0x0 0x10000>;
33 interrupts = <0 36 0x4>; /* Level high type */
38 #interrupt-cells = <2>;
42 Example of gpio-controller node for a ls1028a/ls1088a SoC:
45 compatible = "fsl,ls1028a-gpio", "fsl,ls1088a-gpio", "fsl,qoriq-gpio";
46 reg = <0x0 0x2300000 0x0 0x10000>;
47 interrupts = <GIC_SPI 36 IRQ_TYPE_LEVEL_HIGH>;
51 #interrupt-cells = <2>;
