Changes since v13:
- move dpi dual edge patches to another series because it will have long time
to implement the dual edge change base boris patches.
https://patchwork.kernel.org/cover/11354279/
Changes since v12:
- fix mediatek,dpi.yaml make_dt_binding_check errors.
Change since v11:
- fine tune mediatek,dpi.yaml.
- add Acked-by: Rob Herring <[email protected]>.
Change since v10:
- convert the Documentation/devicetree/bindings/display/mediatek/mediatek,dpi.txt
to yaml format.
- read the pclk-sample in endpoint.
Changes since v9:
- rename pinctrl-names = "gpiomode", "dpimode" to "active", "idle".
- fix some typo.
Changes since v8:
- drop pclk-sample redefine in mediatek,dpi.txt
- only get the gpiomode and dpimode when dpi->pinctrl is successful.
Changes since v7:
- separate dt-bindings to independent patches.
- move dpi dual edge to one patch.
Changes since v6:
- change dual_edge to pclk-sample
- remove dpi_pin_mode_swap and
Changes since v5:
- fine tune the dt-bindings commit message.
Changes since v4:
- move pin mode control and dual edge control to deveice tree.
- update dt-bindings document for pin mode swap and dual edge control.
Changes since v3:
- add dpi pin mode control when dpi on or off.
- update dpi dual edge comment.
Changes since v2:
- update dt-bindings document for mt8183 dpi.
- separate dual edge modfication as independent patch.

-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 "default" and "sleep".
-
-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";
- pinctrl-names = "default", "sleep";
- pinctrl-0 = <&dpi_pin_func>;
- pinctrl-1 = <&dpi_pin_idle>;
-
- port {
- dpi0_out: endpoint {
- remote-endpoint = <&hdmi0_in>;

the dpi pins to gpio mode and output-low to avoid leakage current when dpi
