Ilitek ILI9322 TFT panel driver with SPI control bus
|
|
This is a driver for 320x240 TFT panels, accepting a variety of input
|
streams that get adapted and scaled to the panel. The panel output has
|
960 TFT source driver pins and 240 TFT gate driver pins, VCOM, VCOML and
|
VCOMH outputs.
|
|
Required properties:
|
- compatible: "dlink,dir-685-panel", "ilitek,ili9322"
|
(full system-specific compatible is always required to look up configuration)
|
- reg: address of the panel on the SPI bus
|
|
Optional properties:
|
- vcc-supply: core voltage supply, see regulator/regulator.txt
|
- iovcc-supply: voltage supply for the interface input/output signals,
|
see regulator/regulator.txt
|
- vci-supply: voltage supply for analog parts, see regulator/regulator.txt
|
- reset-gpios: a GPIO spec for the reset pin, see gpio/gpio.txt
|
|
The following optional properties only apply to RGB and YUV input modes and
|
can be omitted for BT.656 input modes:
|
|
- pixelclk-active: see display/panel/display-timing.txt
|
- de-active: see display/panel/display-timing.txt
|
- hsync-active: see display/panel/display-timing.txt
|
- vsync-active: see display/panel/display-timing.txt
|
|
The panel must obey the rules for a SPI slave device as specified in
|
spi/spi-bus.txt
|
|
The device node can contain one 'port' child node with one child
|
'endpoint' node, according to the bindings defined in
|
media/video-interfaces.txt. This node should describe panel's video bus.
|
|
Example:
|
|
panel: display@0 {
|
compatible = "dlink,dir-685-panel", "ilitek,ili9322";
|
reg = <0>;
|
vcc-supply = <&vdisp>;
|
iovcc-supply = <&vdisp>;
|
vci-supply = <&vdisp>;
|
|
port {
|
panel_in: endpoint {
|
remote-endpoint = <&display_out>;
|
};
|
};
|
};
