Mediatek DPI Device
|
||
|
===================
|
||
|
|
||
|
The Mediatek DPI function block is a sink of the display subsystem and
|
||
|
provides 8-bit RGB/YUV444 or 8/10/10-bit YUV422 pixel data on a parallel
|
||
|
output bus.
|
||
|
|
||
|
Required properties:
|
||
|
- compatible: "mediatek,<chip>-dpi"
|
||
|
- reg: Physical base address and length of the controller's registers
|
||
|
- interrupts: The interrupt signal from the function block.
|
||
|
- clocks: device clocks
|
||
|
See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
|
||
|
- clock-names: must contain "pixel", "engine", and "pll"
|
||
|
- port: Output port node with endpoint definitions as described in
|
||
|
Documentation/devicetree/bindings/graph.txt. This port should be connected
|
||
|
to the input port of an attached HDMI or LVDS encoder chip.
|
||
|
|
||
|
Example:
|
||
|
|
||
|
dpi0: dpi@1401d000 {
|
||
|
compatible = "mediatek,mt8173-dpi";
|
||
|
reg = <0 0x1401d000 0 0x1000>;
|
||
|
interrupts = <GIC_SPI 194 IRQ_TYPE_LEVEL_LOW>;
|
||
|
clocks = <&mmsys CLK_MM_DPI_PIXEL>,
|
||
|
<&mmsys CLK_MM_DPI_ENGINE>,
|
||
|
<&apmixedsys CLK_APMIXED_TVDPLL>;
|
||
|
clock-names = "pixel", "engine", "pll";
|
||
|
|
||
|
port {
|
||
|
dpi0_out: endpoint {
|
||
|
remote-endpoint = <&hdmi0_in>;
|
||
|
};
|
||
|
};
|
||
|
};
