Kernel-4.18.0-80.el8_tca6507

LEDs connected to tca6507

Required properties:

• compatible : should be : “ti,tca6507”.
• #address-cells: must be 1
• #size-cells: must be 0
• reg: typically 0x45.

Optional properties:

• gpio-controller: allows lines to be used as output-only GPIOs.
• #gpio-cells: if present, must not be 0.

Each led is represented as a sub-node of the ti,tca6507 device.

LED sub-node properties:

• label : (optional) see Documentation/devicetree/bindings/leds/common.txt
• reg : number of LED line (could be from 0 to 6)
• linux,default-trigger : (optional)
  see Documentation/devicetree/bindings/leds/common.txt
• compatible: either “led” (the default) or “gpio”.

Examples:

tca6507@45 {
compatible = “ti,tca6507”;
#address-cells = <1>;
#size-cells = <0>;
reg = <0x45>;

gpio-controller;
#gpio-cells = <2>;

led0: red-aux@0 {
    label = "red:aux";
    reg = <0x0>;
};

led1: green-aux@1 {
    label = "green:aux";
    reg = <0x5>;
    linux,default-trigger = "default-on";
};

wifi-reset@6 {
    reg = <0x6>;
    compatible = "gpio";
};

};
