Re: [PATCH 3/4] OMAPDSS: panel-sharp-ls037v7dw01: add device tree support

We can pass the GPIO configuration for ls037v7dw01 in a standard
gpios property.

+SHARP LS037V7DW01 TFT-LCD panel
+
+Required properties:
+- compatible: should be "sharp,ls037v7dw01"
+
+Optional properties:
+- reset-gpios: a GPIO spec for the optional reset pin
+- enable-gpios: a GPIO array for the optional configuration GPIOs
+  ordered MO, LR, UD, INI as specified in the LS037V7DW01.pdf file.
+
+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
+
+This panel can have zero to five GPIOs to configure
+to change configuration between QVGA and VGA mode
+and the scan direction. As these pins can be also
+configured with external pulls, all the GPIOs are
+considered optional with holes in the array.
+
+Example when connected to a omap2+ based device:
+
+	lcd0: display {
+		compatible = "sharp,ls037v7dw01";
+		power-supply = <&lcd_3v3>;
+		reset-gpios = <&gpio5 27 GPIO_ACTIVE_HIGH>;	/* gpio155, lcd RESB */
+		enable-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH	/* gpio154, lcd MO */
+				&gpio1 2 GPIO_ACTIVE_HIGH	/* gpio2, lcd LR */
+				&gpio1 3 GPIO_ACTIVE_HIGH	/* gpio3, lcd UD */
+				&gpio5 24 GPIO_ACTIVE_HIGH>;	/* gpio152, lcd INI */
