CSR SiRFatlas7 GPIO controller bindings
Required properties:
- compatible : "sirf,atlas7-gpio"
- reg : Address range of the pinctrl registers
- interrupts : Interrupts used by every GPIO group
- gpio-banks : How many gpio banks on this controller
- gpio-controller : Indicates this device is a GPIO controller
- interrupt-controller : Marks the device node as an interrupt controller
The GPIO controller also acts as an interrupt controller. It uses the default
two cells specifier as described in Documentation/devicetree/bindings/
interrupt-controller/interrupts.txt.
Example:
gpio_0: gpio_mediam@17040000 {
compatible = "sirf,atlas7-gpio";
reg = <0x17040000 0x1000>;
interrupts = <0 13 0>, <0 14 0>;
#gpio-cells = <2>;
#interrupt-cells = <2>;
gpio-controller;
interrupt-controller;
gpio-banks = <2>;
gpio-ranges = <&pinctrl 0 0 0>,
<&pinctrl 32 0 0>;
gpio-ranges-group-names = "lvds_gpio_grp",
"uart_nand_gpio_grp";
};
leds {
compatible = "gpio-leds";
led1 {
gpios = <&gpio_1 15 0>;
...
};
led2 {
gpios = <&gpio_2 34 0>;
...
};
};
Please refer to gpio.txt in this directory for details of the common
gpio properties used by devices.
