But DisplayPort connector_type usecases does need hpd to be enabled. In order not to break any platform from those driver changes, add "no-hpd" property to all the existing sn65dsi86 nodes (that don't have it already) as hpd is not being used there anyways. Signed-off-by: Jayesh Choudhary --- Upcoming driver changes that will break platforms if we do not have this property in all the existing sn65dsi86 nodes that assumes hpd is disabled: (sc7180-trogdor-ti-sn65dsi86.dtsi, sdm850-lenovo-yoga-c630.dts and sdm845-cheza.dtsi already have this property.) NOTE: Grouping the logical changes together in a single patch even though we have multiple vendor dts. I hope that is not an issue. .../boot/dts/amlogic/meson-g12b-bananapi-cm4-mnt-reform2.dts | 1 + arch/arm64/boot/dts/freescale/imx8mq-mnt-reform2.dts | 1 + arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts | 1 + arch/arm64/boot/dts/renesas/r8a779a0-falcon-cpu.dtsi | 1 + arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dts | 1 + arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts | 1 + arch/arm64/boot/dts/renesas/white-hawk-cpu-common.dtsi | 1 + 7 files changed, 7 insertions(+) diff --git a/arch/arm64/boot/dts/amlogic/meson-g12b-bananapi-cm4-mnt-reform2.dts b/arch/arm64/boot/dts/amlogic/meson-g12b-bananapi-cm4-mnt-reform2.dts index 0f48c32bec97..6a7d7db3ef8f 100644 --- a/arch/arm64/boot/dts/amlogic/meson-g12b-bananapi-cm4-mnt-reform2.dts +++ b/arch/arm64/boot/dts/amlogic/meson-g12b-bananapi-cm4-mnt-reform2.dts @@ -292,6 +292,7 @@ edp_bridge: bridge@2c { vpll-supply = <®_main_1v8>; vcca-supply = <®_main_1v2>; vcc-supply = <®_main_1v2>; + no-hpd; ports { #address-cells = <1>; diff --git a/arch/arm64/boot/dts/freescale/imx8mq-mnt-reform2.dts b/arch/arm64/boot/dts/freescale/imx8mq-mnt-reform2.dts index 3ae3824be027..599a53969326 100644 --- a/arch/arm64/boot/dts/freescale/imx8mq-mnt-reform2.dts +++ b/arch/arm64/boot/dts/freescale/imx8mq-mnt-reform2.dts @@ -147,6 +147,7 @@ edp_bridge: bridge@2c { vpll-supply = <®_main_1v8>; vcca-supply = <®_main_1v2>; vcc-supply = <®_main_1v2>; + no-hpd; ports { #address-cells = <1>; diff --git a/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts b/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts index 672ac4c3afa3..8fa18273684f 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts @@ -384,6 +384,7 @@ sn65dsi86_bridge: bridge@2c { clocks = <&rpmhcc RPMH_LN_BB_CLK3>; clock-names = "refclk"; + no-hpd; ports { #address-cells = <1>; diff --git a/arch/arm64/boot/dts/renesas/r8a779a0-falcon-cpu.dtsi b/arch/arm64/boot/dts/renesas/r8a779a0-falcon-cpu.dtsi index 0916fd57d1f1..a115e3fc4cb9 100644 --- a/arch/arm64/boot/dts/renesas/r8a779a0-falcon-cpu.dtsi +++ b/arch/arm64/boot/dts/renesas/r8a779a0-falcon-cpu.dtsi @@ -214,6 +214,7 @@ bridge@2c { vpll-supply = <®_1p8v>; vcca-supply = <®_1p2v>; vcc-supply = <®_1p2v>; + no-hpd; ports { #address-cells = <1>; diff --git a/arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dts b/arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dts index 6955eafd8d6a..fcc2d8edd464 100644 --- a/arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dts +++ b/arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dts @@ -349,6 +349,7 @@ bridge@2c { vpll-supply = <®_1p8v>; vcca-supply = <®_1p2v>; vcc-supply = <®_1p2v>; + no-hpd; ports { #address-cells = <1>; diff --git a/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts b/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts index 4d890e0617af..8b9592b87366 100644 --- a/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts +++ b/arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts @@ -460,6 +460,7 @@ bridge@2c { vpll-supply = <®_1p8v>; vcca-supply = <®_1p2v>; vcc-supply = <®_1p2v>; + no-hpd; ports { #address-cells = <1>; diff --git a/arch/arm64/boot/dts/renesas/white-hawk-cpu-common.dtsi b/arch/arm64/boot/dts/renesas/white-hawk-cpu-common.dtsi index b4024e85ae5a..686a37a8680f 100644 --- a/arch/arm64/boot/dts/renesas/white-hawk-cpu-common.dtsi +++ b/arch/arm64/boot/dts/renesas/white-hawk-cpu-common.dtsi @@ -256,6 +256,7 @@ bridge@2c { vpll-supply = <®_1p8v>; vcca-supply = <®_1p2v>; vcc-supply = <®_1p2v>; + no-hpd; ports { #address-cells = <1>; -- 2.34.1 _______________________________________________ linux-amlogic mailing list linux-amlogic@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-amlogic
