| Bindings for Linear Technologies LT3593 LED controller |
| |
| Required properties: |
| - compatible: Should be "lltc,lt3593". |
| - lltc,ctrl-gpios: A handle to the GPIO that is connected to the 'CTRL' |
| pin of the chip. |
| |
| The hardware supports only one LED. The properties of this LED are |
| configured in a sub-node in the device node. |
| |
| Optional sub-node properties: |
| - label: A label for the LED. If none is given, the LED will be |
| named "lt3595::". |
| - linux,default-trigger: The default trigger for the LED. |
| See Documentation/devicetree/bindings/leds/common.txt |
| - default-state: The initial state of the LED. |
| See Documentation/devicetree/bindings/leds/common.txt |
| |
| If multiple chips of this type are found in a design, each one needs to |
| be handled by its own device node. |
| |
| Example: |
| |
| led-controller { |
| compatible = "lltc,lt3593"; |
| lltc,ctrl-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>; |
| |
| led { |
| label = "white:backlight"; |
| default-state = "on"; |
| }; |
| }; |
