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.

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.
