v2:
- Add min/maxItems to mode-gpios (Rob)
- Fix bug in description, mode is up to three gpios (Rob)

-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>;
- };
- };
-};
