It supports constant current output and sloping current output modes. The chip is connected over I2C. Required properties: - compatible: Must be "panasonic,an30259a". - reg: I2C slave address. - #address-cells: Must be 1. - #size-cells: Must be 0. Each LED is represented as a sub-node of the panasonic,an30259a node. Required sub-node properties: - reg: Pin that the LED is connected to. Must be 1, 2, or 3. Optional sub-node properties: - function : see Documentation/devicetree/bindings/leds/common.txt - color : see Documentation/devicetree/bindings/leds/common.txt - label : see Documentation/devicetree/bindings/leds/common.txt (deprecated) - linux,default-trigger : see Documentation/devicetree/bindings/leds/common.txt Example: #include <dt-bindings/leds/common.h> led-controller@30 { compatible = "panasonic,an30259a"; reg = <0x30>; #address-cells = <1>; #size-cells = <0>; led@1 { reg = <1>; linux,default-trigger = "heartbeat"; function = LED_FUNCTION_INDICATOR; color = <LED_COLOR_ID_RED>; }; led@2 { reg = <2>; function = LED_FUNCTION_INDICATOR; color = <LED_COLOR_ID_GREEN>; }; led@3 { reg = <3>; function = LED_FUNCTION_INDICATOR; color = <LED_COLOR_ID_BLUE>; }; }; |
