Add DP device node on sc7180. Changes in v2: - Add assigned-clocks and assigned-clock-parents - Remove cell-index and pixel_rcg - Change compatible to qcom,sc7180-dp Changes in v3: - Update commit text - Make DP child node of MDSS - Remove data-lanes property from SOC dts - Disable DP node in SOC dts - Assign DP to Port2 in MDP node - Add MDSS AHB clock in DP device node Changes in v4: - Remove redundant reg-names property - Use IRQ flag instead had hard coded value. - Add link clock source in assigned-clocks list. Changes in v5: - Add OPP table and power-domains for DisplayPort This patch depends-on following series: https://lore.kernel.org/dri-devel/20200807071718.17937-1-tanmay@xxxxxxxxxxxxxx/ Signed-off-by: Tanmay Shah <tanmay@xxxxxxxxxxxxxx> Co-developed-by: Kuogee Hsieh <khsieh@xxxxxxxxxxxxxx> Signed-off-by: Kuogee Hsieh <khsieh@xxxxxxxxxxxxxx> --- arch/arm64/boot/dts/qcom/sc7180.dtsi | 76 +++++++++++++++++++++++++++- 1 file changed, 74 insertions(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sc7180.dtsi b/arch/arm64/boot/dts/qcom/sc7180.dtsi index 31b9217bb5bf..2998fae863a7 100644 --- a/arch/arm64/boot/dts/qcom/sc7180.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7180.dtsi @@ -2371,6 +2371,13 @@ dpu_intf1_out: endpoint { remote-endpoint = <&dsi0_in>; }; }; + + port@2 { + reg = <2>; + dpu_intf0_out: endpoint { + remote-endpoint = <&dp_in>; + }; + }; }; }; @@ -2440,6 +2447,71 @@ dsi_phy: dsi-phy@ae94400 { status = "disabled"; }; + + msm_dp: displayport-controller@ae90000 { + status = "disabled"; + compatible = "qcom,sc7180-dp"; + + reg = <0 0x0ae90000 0 0x1400>; + + interrupt-parent = <&mdss>; + interrupts = <12 IRQ_TYPE_NONE>; + + clocks = <&dispcc DISP_CC_MDSS_AHB_CLK>, + <&dispcc DISP_CC_MDSS_DP_AUX_CLK>, + <&dispcc DISP_CC_MDSS_DP_LINK_CLK>, + <&dispcc DISP_CC_MDSS_DP_LINK_INTF_CLK>, + <&dispcc DISP_CC_MDSS_DP_PIXEL_CLK>; + clock-names = "core_iface", "core_aux", "ctrl_link", + "ctrl_link_iface", "stream_pixel"; + #clock-cells = <1>; + assigned-clocks = <&dispcc DISP_CC_MDSS_DP_LINK_CLK_SRC>, + <&dispcc DISP_CC_MDSS_DP_PIXEL_CLK_SRC>; + assigned-clock-parents = <&msm_dp 0>, <&msm_dp 1>; + + operating-points-v2 = <&dp_opp_table>; + power-domains = <&rpmhpd SC7180_CX>; + + ports { + #address-cells = <1>; + #size-cells = <0>; + port@0 { + reg = <0>; + dp_in: endpoint { + remote-endpoint = <&dpu_intf0_out>; + }; + }; + + port@1 { + reg = <1>; + dp_out: endpoint { }; + }; + }; + + dp_opp_table: dp-opp-table { + compatible = "operating-points-v2"; + + opp-160000000 { + opp-hz = /bits/ 64 <160000000>; + required-opps = <&rpmhpd_opp_low_svs>; + }; + + opp-270000000 { + opp-hz = /bits/ 64 <270000000>; + required-opps = <&rpmhpd_opp_svs>; + }; + + opp-540000000 { + opp-hz = /bits/ 64 <540000000>; + required-opps = <&rpmhpd_opp_svs_l1>; + }; + + opp-810000000 { + opp-hz = /bits/ 64 <810000000>; + required-opps = <&rpmhpd_opp_nom>; + }; + }; + }; }; dispcc: clock-controller@af00000 { @@ -2449,8 +2521,8 @@ dispcc: clock-controller@af00000 { <&gcc GCC_DISP_GPLL0_CLK_SRC>, <&dsi_phy 0>, <&dsi_phy 1>, - <0>, - <0>; + <&msm_dp 0>, + <&msm_dp 1>; clock-names = "bi_tcxo", "gcc_disp_gpll0_clk_src", "dsi0_phy_pll_out_byteclk", -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
