-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"
-  the supported chips are mt2701 , 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 "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.
-
-Optional properties:
-- pinctrl-names: Contain "gpiomode" and "dpimode".
-  pinctrl-names see Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-- pclk-sample: refer Documentation/devicetree/bindings/media/video-interfaces.txt.
-
-Example:
-
-dpi0: dpi at 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";
-	pinctrl-names = "active", "idle";
-	pinctrl-0 = <&dpi_pin_func>;
-	pinctrl-1 = <&dpi_pin_idle>;
-
-	port {
-		dpi0_out: endpoint {
-			pclk-sample = <0>;
-			remote-endpoint = <&hdmi0_in>;
-		};
-	};
-};
