| |
| 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: |
| - label: see Documentation/devicetree/bindings/leds/common.txt |
| - linux,default-trigger: see Documentation/devicetree/bindings/leds/common.txt |

| Example: |
| led-controller@30 { |
| compatible = "panasonic,an30259a"; |
| reg = <0x30>; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| |
| led@1 { |
| reg = <1>; |
| linux,default-trigger = "heartbeat"; |
| label = "red:indicator"; |
| }; |
| |
| led@2 { |
| reg = <2>; |
| label = "green:indicator"; |
| }; |
