Convert binding doc leds-lm3592x to yaml format.
Additional change:
- Add ref to common.yaml for child node.
- Add i2c node at example.
Fix below warning:
arch/arm64/boot/dts/freescale/imx8mq-librem5-r2.dtb: /soc@0/bus@30800000/i2c@30a40000/backlight@36:
failed to match any schema with compatible: ['ti,lm36922']
Signed-off-by: Frank Li <Frank.Li@xxxxxxx>
---
change from v2 to v3:
- add . after sentence.
- use led@[0-3]
- add allOf: disable led@3 for lm36922
Change from v1 to v2:
- fix dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/leds/ti.lm36922.example.dtb: /example-0/i2c/led-controller@36: failed to match any schema with compatible: ['ti,lm3692x']

-* Texas Instruments - LM3692x Highly Efficient White LED Driver
-
-The LM3692x is an ultra-compact, highly efficient,
-white-LED driver designed for LCD display backlighting.
-
-The main difference between the LM36922 and LM36923 is the number of
-LED strings it supports. The LM36922 supports two strings while the LM36923
-supports three strings.
-
-Required properties:
- - compatible:
- "ti,lm36922"
- "ti,lm36923"
- - reg : I2C slave address
- - #address-cells : 1
- - #size-cells : 0
-
-Optional properties:
- - enable-gpios : gpio pin to enable/disable the device.
- - vled-supply : LED supply
- - ti,ovp-microvolt: Overvoltage protection in
- micro-volt, can be 17000000, 21000000, 25000000 or
- 29000000. If ti,ovp-microvolt is not specified it
- defaults to 29000000.
-
-Required child properties:
- - reg : 0 - Will enable all LED sync paths
- 1 - Will enable the LED1 sync
- 2 - Will enable the LED2 sync
- 3 - Will enable the LED3 sync (LM36923 only)
-
-Optional child properties:
- - function : see Documentation/devicetree/bindings/leds/common.txt
- - color : see Documentation/devicetree/bindings/leds/common.txt
- - label : see Documentation/devicetree/bindings/leds/common.txt (deprecated)
- - linux,default-trigger :
- see Documentation/devicetree/bindings/leds/common.txt
- - led-max-microamp :
- see Documentation/devicetree/bindings/leds/common.txt
-
-Example:
-
-#include <dt-bindings/leds/common.h>
-
-led-controller@36 {
- compatible = "ti,lm3692x";
- reg = <0x36>;
- #address-cells = <1>;

- vled-supply = <&vbatt>;
- ti,ovp-microvolt = <29000000>;

- linux,default-trigger = "backlight";
- led-max-microamp = <20000>;
