Wei Chenf9367792015-05-18 07:28:32 +00001CSR SiRFatlas7 GPIO controller bindings
2
3Required properties:
4- compatible : "sirf,atlas7-gpio"
5- reg : Address range of the pinctrl registers
6- interrupts : Interrupts used by every GPIO group
7- gpio-banks : How many gpio banks on this controller
8- gpio-controller : Indicates this device is a GPIO controller
9- interrupt-controller : Marks the device node as an interrupt controller
10
11The GPIO controller also acts as an interrupt controller. It uses the default
12two cells specifier as described in Documentation/devicetree/bindings/
13interrupt-controller/interrupts.txt.

15Example:
16
17 gpio_0: gpio_mediam@17040000 {
18 compatible = "sirf,atlas7-gpio";
19 reg = <0x17040000 0x1000>;
20 interrupts = <0 13 0>, <0 14 0>;
21
22 #gpio-cells = <2>;
23 #interrupt-cells = <2>;
24
25 gpio-controller;
26 interrupt-controller;
27
28 gpio-banks = <2>;
29 gpio-ranges = <&pinctrl 0 0 0>,
30 <&pinctrl 32 0 0>;
31 gpio-ranges-group-names = "lvds_gpio_grp",
32 "uart_nand_gpio_grp";
33 };
34
35 leds {
36 compatible = "gpio-leds";
37
38 led1 {
39 gpios = <&gpio_1 15 0>;
40 ...
41 };
42
43 led2 {
44 gpios = <&gpio_2 34 0>;
45 ...
46 };
47 };

50gpio properties used by devices.
