1* Analog Devices ADP1653 flash LED driver
2
3Required Properties:
4
5  - compatible: Must contain "adi,adp1653"
6
7  - reg: I2C slave address
8
9  - enable-gpios: Specifier of the GPIO connected to EN pin
10
11There are two LED outputs available - flash and indicator. One LED is
12represented by one child node, nodes need to be named "flash" and "indicator".
13
14Required properties of the LED child node:
15- led-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
16
17Required properties of the flash LED child node:
18
19- flash-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
20- flash-timeout-us : see Documentation/devicetree/bindings/leds/common.txt
21- led-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
22
23Example:
24
25	adp1653: led-controller@30 {
26		compatible = "adi,adp1653";
27		reg = <0x30>;
28		enable-gpios = <&gpio3 24 GPIO_ACTIVE_HIGH>; /* 88 */
29
30		flash {
31			flash-timeout-us = <500000>;
32			flash-max-microamp = <320000>;
33			led-max-microamp = <50000>;
34		};
35		indicator {
36			led-max-microamp = <17500>;
37		};
38	};
