-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, mt7623, mt8167, mt8173 and mt8183.
-- 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.
-
-Optional properties:
-- resets: list of phandle + reset specifier pair, as described in [1].
-
-[1] Documentation/devicetree/bindings/reset/reset.txt

-MIPI TX Configuration Module
-============================
-
-See phy/mediatek,dsi-phy.yaml
-
-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>;
-       drive-strength-microamp = <4600>;
-       nvmem-cells= <&mipi_tx_calibration>;
-       nvmem-cell-names = "calibration-data";
-};
-

-       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>,
