-Generic MIPI DPI Panel
-======================
-
-Required properties:
-- compatible: "panel-dpi"
-
-Optional properties:
-- label: a symbolic name for the panel
-- enable-gpios: panel enable gpio
-- reset-gpios: GPIO to control the RESET pin
-- vcc-supply: phandle of regulator that will be used to enable power to the display
-- backlight: phandle of the backlight device
-
-Required nodes:
-- "panel-timing" containing video timings
-  (Documentation/devicetree/bindings/display/panel/display-timing.txt)
-- Video port for DPI input
-
-Example
--------
