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>;
|
||
|
|
...
|
||
|
|
};
|
||
|
|
};
