As you can see, this Purwa file was copied from the latest hamoa-iot-evk.dts. However, not all nodes have been verified on Purwa. Therefore, I need to retain only the functions that work correctly and keep them aligned with the nodes from my initial version. The deleted nodes will be updated later by the respective authors from different technical areas. > >> - >> wcd938x: audio-codec { >> compatible = "qcom,wcd9385-codec"; >> >> @@ -60,32 +50,6 @@ chosen { >> stdout-path = "serial0:115200n8"; >> }; >> >> - connector3 { >> - compatible = "usb-a-connector"; >> - label = "USB-3-Type-A"; >> - power-role = "source"; >> - >> - vbus-supply = <®ulator_usb3_vbus>; >> - >> - port { >> - connector_3_in: endpoint { >> - }; >> - }; >> - }; >> - >> - connector6 { >> - compatible = "usb-a-connector"; >> - label = "USB-6-Type-A"; >> - power-role = "source"; >> - >> - vbus-supply = <®ulator_usb6_vbus>; >> - >> - port { >> - connector_4_in: endpoint { >> - }; >> - }; >> - }; > > Are there no Type-A ports? ditto > > [...] > >> panel { >> compatible = "edp-panel"; >> >> - backlight = <&backlight>; >> + //backlight = <&backlight>; > > FWIW we can't merge dead code I will update. > >> power-supply = <&vreg_edp_3p3>; >> >> port { >> @@ -920,23 +886,6 @@ &mdss_dp3_phy { >> status = "okay"; >> }; >> >> -&pcie4_port0 { >> - wifi@0 { >> - compatible = "pci17cb,1107"; >> - reg = <0x10000 0x0 0x0 0x0 0x0>; >> - >> - vddaon-supply = <&vreg_pmu_aon_0p59>; >> - vddwlcx-supply = <&vreg_pmu_wlcx_0p8>; >> - vddwlmx-supply = <&vreg_pmu_wlmx_0p85>; >> - vddrfacmn-supply = <&vreg_pmu_rfa_cmn>; >> - vddrfa0p8-supply = <&vreg_pmu_rfa_0p8>; >> - vddrfa1p2-supply = <&vreg_pmu_rfa_1p2>; >> - vddrfa1p8-supply = <&vreg_pmu_rfa_1p8>; >> - vddpcie0p9-supply = <&vreg_pmu_pcie_0p9>; >> - vddpcie1p8-supply = <&vreg_pmu_pcie_1p8>; >> - }; >> -}; > > Is the Wi-Fi solution different? ditto > > Konrad -- Best Regards, Yijie
