+SHARP LS037V7DW01 TFT-LCD panel
+===================================
+
+Required properties:
+- compatible: "sharp,ls037v7dw01"
+
+Optional properties:
+- label: a symbolic name for the panel
+- enable-gpios: a GPIO spec for the optional enable pin.
+  This pin is the INI pin as specified in the LS037V7DW01.pdf file.
+- reset-gpios: a GPIO spec for the optional reset pin.
+  This pin is the RESB pin as specified in the LS037V7DW01.pdf file.
+- mode-gpios: a GPIO
+  ordered MO, LR, and UD as specified in the LS037V7DW01.pdf file.
+
+Required nodes:
+- Video port for DPI input
+
+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
+-------
+
+Example when connected to a omap2+ based device:
+
+lcd0: display {
+       compatible = "sharp,ls037v7dw01";
+       power-supply = <&lcd_3v3>;
+       enable-gpios = <&gpio5 24 GPIO_ACTIVE_HIGH>;    /* gpio152, lcd INI */
+       reset-gpios = <&gpio5 27 GPIO_ACTIVE_HIGH>;     /* gpio155, lcd RESB */
+       mode-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 */
+
+       port {
+               lcd_in: endpoint {
+                       remote-endpoint = <&dpi_out>;
+               };
+       };
+};
