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.
