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"; }; };
