This is based on work from Jonathan Marek. Signed-off-by: Brian Masney Reviewed-by: Linus Walleij --- Changes since v1: - Add hdmi_pll to hdmi-phy node - add power-domain to hdmi-phy per binding specification - Remove FIXME comment regarding the hpd-gdsc-supply. I saw a recent post on linux-arm-msm that this is present for running the upstream MSM display driver on the downstream kernel. arch/arm/boot/dts/qcom-msm8974.dtsi | 78 +++++++++++++++++++++++++++++ 1 file changed, 78 insertions(+) diff --git a/arch/arm/boot/dts/qcom-msm8974.dtsi b/arch/arm/boot/dts/qcom-msm8974.dtsi index 7fc23e422cc5..af02eace14e2 100644 --- a/arch/arm/boot/dts/qcom-msm8974.dtsi +++ b/arch/arm/boot/dts/qcom-msm8974.dtsi @@ -1258,6 +1258,13 @@ port@0 { reg = <0>; + mdp5_intf3_out: endpoint { + remote-endpoint = <&hdmi_in>; + }; + }; + + port@1 { + reg = <1>; mdp5_intf1_out: endpoint { remote-endpoint = <&dsi0_in>; }; @@ -1335,6 +1342,77 @@ clocks = <&mmcc MDSS_AHB_CLK>; clock-names = "iface"; }; + + hdmi: hdmi-tx@fd922100 { + status = "disabled"; + + compatible = "qcom,hdmi-tx-8974"; + reg = <0xfd922100 0x35c>, + <0xfc4b8000 0x60f0>; + reg-names = "core_physical", + "qfprom_physical"; + + interrupt-parent = <&mdss>; + interrupts = <8 IRQ_TYPE_LEVEL_HIGH>; + + power-domains = <&mmcc MDSS_GDSC>; + + clocks = <&mmcc MDSS_MDP_CLK>, + <&mmcc MDSS_AHB_CLK>, + <&mmcc MDSS_HDMI_CLK>, + <&mmcc MDSS_HDMI_AHB_CLK>, + <&mmcc MDSS_EXTPCLK_CLK>; + clock-names = "mdp_core", + "iface", + "core", + "alt_iface", + "extp"; + + hpd-5v-supply = <&pm8941_5vs2>; + core-vdda-supply = <&pm8941_l12>; + core-vcc-supply = <&pm8941_s3>; + + phys = <&hdmi_phy>; + phy-names = "hdmi_phy"; + + ports { + #address-cells = <1>; + #size-cells = <0>; + + port@0 { + reg = <0>; + hdmi_in: endpoint { + remote-endpoint = <&mdp5_intf3_out>; + }; + }; + + port@1 { + reg = <1>; + }; + }; + }; + + hdmi_phy: hdmi-phy@fd922500 { + status = "disabled"; + + compatible = "qcom,hdmi-phy-8974"; + reg = <0xfd922500 0x7c>, + <0xfd922700 0xd4>; + reg-names = "hdmi_phy", + "hdmi_pll"; + + clocks = <&mmcc MDSS_AHB_CLK>, + <&mmcc MDSS_HDMI_AHB_CLK>; + clock-names = "iface", + "alt_iface"; + + core-vdda-supply = <&pm8941_l12>; + vddio-supply = <&pm8941_s3>; + + power-domains = <&mmcc MDSS_GDSC>; + + #phy-cells = <0>; + }; }; };
