This adds a new binding for Himax HX8357D display panels. It includes a compatible string for one display (more can be added in the future).

Himax HX8357D display panels
This binding is for display panels using a Himax HX8357D controller in SPI
mode, such as the Adafruit 3.5" TFT for Raspberry Pi.
Required properties:
- compatible: "adafruit,yx350hv15", "himax,hx8357d"
- dc-gpios: D/C pin
- reg: address of the panel on the SPI bus
The node for this driver must be a child node of a SPI controller, hence
all mandatory properties described in ../spi/spi-bus.txt must be specified.
Optional properties:
- rotation: panel rotation in degrees counter clockwise (0,90,180,270)
- backlight: phandle of the backlight device attached to the panel
Example:
display@0{
compatible = "adafruit,yx350hv15", "himax,hx8357d";
reg = <0>;
spi-max-frequency = <32000000>;
dc-gpios = <&gpio0 25 GPIO_ACTIVE_HIGH>;
rotation = <90>;
backlight = <&backlight>;
};
