Subject: [PATCH v3 2/3] dt-bindings: leds: is31fl32xx: convert the binding
to yaml
From: Lucca Fachinetti <luccafachinetti@...il.com>
Keep the old maintainers field as is.
Add datasheets for reference, NB that I was not able to find an
up-to-date, funtional direct URL for si-en products datasheet
so they were skipped.

-Binding for ISSI IS31FL32xx and Si-En SN32xx LED Drivers
-
-The IS31FL32xx/SN32xx family of LED drivers are I2C devices with multiple
-constant-current channels, each with independent 256-level PWM control.
-Each LED is represented as a sub-node of the device.
-
-Required properties:
-- compatible: one of
- issi,is31fl3236
- issi,is31fl3235
- issi,is31fl3218
- issi,is31fl3216
- si-en,sn3218
- si-en,sn3216
-- reg: I2C slave address
-- address-cells : must be 1
-- size-cells : must be 0
-
-LED sub-node properties:
-- reg : LED channel number (1..N)
-- label : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- linux,default-trigger : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-

-Example:
-
-is31fl3236: led-controller@3c {
- compatible = "issi,is31fl3236";
- reg = <0x3c>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- led@1 {
- reg = <1>;
- label = "EB:blue:usr0";
- };
- led@2 {
- reg = <2>;
- label = "EB:blue:usr1";
- };
