Qualcomm Technologies, Inc. TRI_LED driver specific bindings



This binding document describes the properties of TRI_LED module in

Qualcomm Technologies, Inc. PMIC chips.



- compatible:

	Usage: required

	Value type: <string>

	Definition: Must be "qcom,tri-led".



- reg:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: Register base of the TRI_LED module and length.



- nvmem-names:

	Usage: optional

	Value type: <string>

	Definition: Nvmem device name for SDAM to do PBS trigger. It must be

		defined as "pbs_sdam". This is required only for HR_LEDs.



- nvmem:

	Usage: optional

	Value type: <phandle>

	Definition: Phandle of the nvmem device name to access SDAM to do PBS

		trigger. This is required only for HR_LEDs.



Properties for child nodes:

- pwms:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: The PWM device (phandle) used for controlling LED.



- led-sources:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: see Documentation/devicetree/bindings/leds/common.txt;

		Device current output identifiers are: 0 - LED1_EN,

		1 - LED2_EN, 2 - LED3_EN.



- label:

	Usage: optional

	Value type: <string>

	Definition: see Documentation/devicetree/bindings/leds/common.txt;



- linux,default-trigger:

	Usage: optional

	Value_type: <string>

	Definition: see Documentation/devicetree/bindings/leds/common.txt;



Example:



	pmi8998_rgb: tri-led@d000{

		compatible = "qcom,tri-led";

		reg = <0xd000 0x100>;



		red {

			label = "red";

			pwms = <&pmi8998_lpg 4 1000000>;

			led-sources = <0>;

		};

		green {

			label = "green";

			pwms = <&pmi8998_lpg 3 1000000>;

			led-sources = <1>;

		};

		blue {

			label = "blue";

			pwms = <&pmi8998_lpg 2 1000000>;

			led-sources = <2>;

		};

	};
