1* Panasonic AN30259A 3-channel LED driver 2 3The AN30259A is a LED controller capable of driving three LEDs independently. It supports 4constant current output and sloping current output modes. The chip is connected over I2C. 5 6Required properties: 7 - compatible: Must be "panasonic,an30259a". 8 - reg: I2C slave address. 9 - #address-cells: Must be 1. 10 - #size-cells: Must be 0. 11 12Each LED is represented as a sub-node of the panasonic,an30259a node. 13 14Required sub-node properties: 15 - reg: Pin that the LED is connected to. Must be 1, 2, or 3. 16 17Optional sub-node properties: 18 - function : 19 see Documentation/devicetree/bindings/leds/common.txt 20 - color : 21 see Documentation/devicetree/bindings/leds/common.txt 22 - label : 23 see Documentation/devicetree/bindings/leds/common.txt (deprecated) 24 - linux,default-trigger : 25 see Documentation/devicetree/bindings/leds/common.txt 26 27Example: 28 29#include <dt-bindings/leds/common.h> 30 31led-controller@30 { 32 compatible = "panasonic,an30259a"; 33 reg = <0x30>; 34 #address-cells = <1>; 35 #size-cells = <0>; 36 37 led@1 { 38 reg = <1>; 39 linux,default-trigger = "heartbeat"; 40 function = LED_FUNCTION_INDICATOR; 41 color = <LED_COLOR_ID_RED>; 42 }; 43 44 led@2 { 45 reg = <2>; 46 function = LED_FUNCTION_INDICATOR; 47 color = <LED_COLOR_ID_GREEN>; 48 }; 49 50 led@3 { 51 reg = <3>; 52 function = LED_FUNCTION_INDICATOR; 53 color = <LED_COLOR_ID_BLUE>; 54 }; 55}; 56
