[PATCH v16 0/1] mt8183 dpi support pin mode swap

[PATCH v16 0/1] mt8183 dpi support pin mode swap

[Jitao Shi]

Changes since v15:
 - Fix YAML License to (GPL-2.0-only OR BSD-2-Clause).
 - "dt-bindings: display: mediatek: control dpi pins mode to avoid leakage"
   "drm/mediatek: set dpi pin mode to gpio low to avoid leakage current"
   applied v15. The links are https://patchwork.kernel.org/patch/11489545/
   https://patchwork.kernel.org/patch/11489577/

Changes since v14:
 - add "Acked-by" and "Reviewed-by"
 - change port@0 to port in yaml

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 <robh@kernel.org>.

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>;
-		};
-	};
-};

My bot found errors running 'make dt_binding_check' on your patch:

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/mediatek/mediatek,dpi.example.dt.yaml: example-0: dpi@1401d000:reg:0: [0, 335663104, 0, 4096] is too long


See https://patchwork.ozlabs.org/patch/1308901

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.
