Subject: [PATCH v1] dt-bindings: leds: pca955x: Convert text bindings to YAML
From: Ricky CX Wu <ricky.cx.wu.wiwynn@...il.com>
Convert the text bindings of pca955x to YAML so it could be used to
validate the DTS.

-* NXP - pca955x LED driver
-
-The PCA955x family of chips are I2C LED blinkers whose pins not used
-to control LEDs can be used as general purpose I/Os. The GPIO pins can
-be input or output, and output pins can also be pulse-width controlled.
-
-Required properties:
-- compatible : should be one of :
- "nxp,pca9550"
- "nxp,pca9551"
- "nxp,pca9552"
- "ibm,pca9552"
- "nxp,pca9553"
-- #address-cells: must be 1
-- #size-cells: must be 0
-- reg: I2C slave address. depends on the model.
-
-Optional properties:
-- gpio-controller: allows pins to be used as GPIOs.
-- #gpio-cells: must be 2.
-- gpio-line-names: define the names of the GPIO lines
-
-LED sub-node properties:
-- reg : number of LED line.
- from 0 to 1 for the pca9550
- from 0 to 7 for the pca9551
- from 0 to 15 for the pca9552
- from 0 to 3 for the pca9553
-- type: (optional) either
- PCA955X_TYPE_NONE
- PCA955X_TYPE_LED
- PCA955X_TYPE_GPIO
- see dt-bindings/leds/leds-pca955x.h (default to LED)
-- label : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- linux,default-trigger : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-
-Examples:
-
-pca9552: pca9552@60 {
- compatible = "nxp,pca9552";
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0x60>;
