Mediatek DSI Device
===================
The Mediatek DSI function block is a sink of the display subsystem and can
drive up to 4-lane MIPI DSI output. Two DSIs can be synchronized for dual-
channel output.
Required properties:
- compatible: "mediatek,<chip>-dsi"
the supported chips are mt2701 and mt8173.
- 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 "engine", "digital", and "hs"
- phys: phandle link to the MIPI D-PHY controller.
- phy-names: must contain "dphy"
- 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 DSI panel or DSI-to-eDP encoder chip.
MIPI TX Configuration Module
============================
The MIPI TX configuration module controls the MIPI D-PHY.
Required properties:
- compatible: "mediatek,<chip>-mipi-tx"
the supported chips are mt2701 and mt8173.
- reg: Physical base address and length of the controller's registers
- clocks: PLL reference clock
- clock-output-names: name of the output clock line to the DSI encoder
- #clock-cells: must be <0>;
- #phy-cells: must be <0>.
Example:
mipi_tx0: mipi-dphy@10215000 {
compatible = "mediatek,mt8173-mipi-tx";
reg = <0 0x10215000 0 0x1000>;
clocks = <&clk26m>;
clock-output-names = "mipi_tx0_pll";
#clock-cells = <0>;
#phy-cells = <0>;
};
dsi0: dsi@1401b000 {
compatible = "mediatek,mt8173-dsi";
reg = <0 0x1401b000 0 0x1000>;
interrupts = <GIC_SPI 192 IRQ_TYPE_LEVEL_LOW>;
clocks = <&mmsys MM_DSI0_ENGINE>, <&mmsys MM_DSI0_DIGITAL>,
<&mipi_tx0>;
clock-names = "engine", "digital", "hs";
phys = <&mipi_tx0>;
phy-names = "dphy";
port {
dsi0_out: endpoint {
remote-endpoint = <&panel_in>;
};
};
};
