Kernel-4.18.0-80.el8_gpio-atlas7

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>;
        ...
    };
};

gpio properties used by devices.
