Also add link-frequencies property into dp_out endpoint as well. The last frequency specified at link-frequencies will be the max link rate supported by DP. Changes in v5: -- revert changes at sc7180.dtsi and sc7280.dtsi -- add &dp_out to sc7180-trogdor.dtsi and sc7280-herobrine.dtsi Changes in v6: -- add data-lanes and link-frequencies to yaml Changes in v7: -- change 160000000 to 1620000000 -- separate yaml to different patch Changes in v8: -- correct Bjorn mail address to kernel.org Changes in v9: -- use symbol rate (hz) for link-frequencies at dp_out at sc7180_trogdor.dtsi Changes in v13: -- delete an extra space at data-lanes Changes in v15: -- replace space with tab at sc7180-trogdor.dtsi Signed-off-by: Kuogee Hsieh <quic_khsieh@...cinc.com> --- arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi | 4 ++++ arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi | 4 ++++ 2 files changed, 8 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi b/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi index eae22e6..ad98a87 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi @@ -814,7 +814,11 @@ hp_i2c: &i2c9 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&dp_hot_plug_det>; +}; + +&dp_out { data-lanes = <0 1>; + link-frequencies = /bits/ 64 <1620000000 2700000000 5400000000>; }; &pm6150_adc { diff --git a/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi b/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi index c11e371..3f363f8 100644 --- a/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi @@ -442,7 +442,11 @@ ap_i2c_tpm: &i2c14 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&dp_hot_plug_det>; +}; + +&dp_out { data-lanes = <0 1>; + link-frequencies = /bits/ 64 <1620000000 2700000000 5400000000 8100000000>; }; &mdss_mdp { -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
