I would prefer that we keep the label prefix "mdssM_dpN" on the DP TX and DP PHY nodes, to keep them neatly sorted in the dts.

(If you name > half mdssM_edp_phyN and half mdssM_dp_phyN we're going to have a mess) Can we use the following naming conventions for clarity : mdssM_dpN_phy to refer to any DP PHY nodes and mdssM_dpN to refer to DP TX nodes. For example, the phy being used by dp0 on mdss0 can be referred by mdss0_dp0_phy, whereas the phy being used by dp1 on mdss0 can be referred by mdss0_dp1_phy. > >> + >> + reg = <0x0 0xaec2a00 0x0 0x200>, >> + <0x0 0xaec2200 0x0 0xd0>, >> + <0x0 0xaec2600 0x0 0xd0>, >> + <0x0 0xaec2000 0x0 0x1c8>; >> + >> + clocks = <&rpmhcc RPMH_CXO_CLK>, >> + <&gcc GCC_EDP_REF_CLKREF_EN>; >> + clock-names = "aux", >> + "cfg_ahb"; >> + >> + vdda-phy-supply = <&vreg_l1c>; >> + vdda-pll-supply = <&vreg_l4a>; >> + #clock-cells = <1>; >> + #phy-cells = <0>; >> + >> + status = "disabled"; >> + }; >> + >> + mdss0_dp0: displayport-controller@af54000 { >> + compatible = "qcom,sa8775p-dp"; >> + >> + pinctrl-0 = <&dp_hot_plug_det>; > Don't make references from .dtsi to labels defined in .dts. > > Regards, > Bjorn Sure, we will make the necessary changes in the next version. > >> + pinctrl-names = "default"; >> + >> + reg = <0x0 0xaf54000 0x0 0x104>, >> + <0x0 0xaf54200 0x0 0x0c0>, >> + <0x0 0xaf55000 0x0 0x770>, >> + <0x0 0xaf56000 0x0 0x09c>; >> + >> + interrupt-parent = <&mdss0>; >> + interrupts = <12>; >> + >> + clocks = <&dispcc0 MDSS_DISP_CC_MDSS_AHB_CLK>, >> + <&dispcc0 MDSS_DISP_CC_MDSS_DPTX0_AUX_CLK>, >> + <&dispcc0 MDSS_DISP_CC_MDSS_DPTX0_LINK_CLK>, >> + <&dispcc0 MDSS_DISP_CC_MDSS_DPTX0_LINK_INTF_CLK>, >> + <&dispcc0 MDSS_DISP_CC_MDSS_DPTX0_PIXEL0_CLK>; >> + clock-names = "core_iface", >> + "core_aux", >> + "ctrl_link", >> + "ctrl_link_iface", >> + "stream_pixel"; >> + assigned-clocks = <&dispcc0 MDSS_DISP_CC_MDSS_DPTX0_LINK_CLK_SRC>, >> + <&dispcc0 MDSS_DISP_CC_MDSS_DPTX0_PIXEL0_CLK_SRC>; >> + assigned-clock-parents = <&mdss0_edp_phy0 0>, <&mdss0_edp_phy0 1>; >> + phys = <&mdss0_edp_phy0>; >> + phy-names = "dp"; >> + >> + operating-points-v2 = <&dp_opp_table>; >> + power-domains = <&rpmhpd SA8775P_MMCX>; >> + >> + #sound-dai-cells = <0>; >> + >> + status = "disabled"; >> + >> + ports { >> + #address-cells = <1>; >> + #size-cells = <0>; >> + >> + port@0 { >> + reg = <0>; >> + mdss0_dp0_in: endpoint { >> + remote-endpoint = <&dpu_intf0_out>; >> + }; >> + }; >> + >> + port@1 { >> + reg = <1>; >> + mdss0_dp0_out: endpoint { }; >> + }; >> + }; >> + >> + dp_opp_table: 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>; >> + }; >> + }; >> + }; >> }; >> >> dispcc0: clock-controller@af00000 { >> @@ -3372,7 +3484,7 @@ >> <&rpmhcc RPMH_CXO_CLK>, >> <&rpmhcc RPMH_CXO_CLK_A>, >> <&sleep_clk>, >> - <0>, <0>, <0>, <0>, >> + <&mdss0_edp_phy0 0>, <&mdss0_edp_phy0 1>, <0>, <0>, >> <0>, <0>, <0>, <0>; >> power-domains = <&rpmhpd SA8775P_MMCX>; >> #clock-cells = <1>; >> -- >> 2.17.1 >>
