[PATCH] dt-bindings: gpio: nxp,lpc3220-gpio: Convert to dtschema

[Animesh Agarwal]

Convert the NXP LPC3220 SoC GPIO controller bindings to DT schema format.

Changes in v2:
  - Changed the file name to match the compatible string.
  - Removed optional from the description of '#gpio-cells' as it was wrongly
    present.

-NXP LPC32xx SoC GPIO controller

-Required properties:
-- compatible: must be "nxp,lpc3220-gpio"
-- reg: Physical base address and length of the controller's registers.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be 3:
-   1) bank:
-      0: GPIO P0
-      1: GPIO P1
-      2: GPIO P2
-      3: GPIO P3
-      4: GPI P3
-      5: GPO P3
-   2) pin number
-   3) optional parameters:
-      - bit 0 specifies polarity (0 for normal, 1 for inverted)
-- reg: Index of the GPIO group
-
-Example:
-
-	gpio: gpio at 40028000 {
-		compatible = "nxp,lpc3220-gpio";
-		reg = <0x40028000 0x1000>;
-		gpio-controller;
-		#gpio-cells = <3>; /* bank, pin, flags */
-	};
-
-	leds {
-		compatible = "gpio-leds";
-
-		led0 {
-			gpios = <&gpio 5 1 1>; /* GPO_P3 1, active low */
-			linux,default-trigger = "heartbeat";
-			default-state = "off";
-		};
-
-		led1 {
-			gpios = <&gpio 5 14 1>; /* GPO_P3 14, active low */
-			linux,default-trigger = "timer";
-			default-state = "off";
-		};
-	};
