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