I have revised it in v4. https://lore.kernel.org/all/20260806-hamoa-come-v4-v4-0-706021d4bc8c@oss.qualcomm.com/ The platform consists of an Advantech SOM-6820 system-on-module (SoM) mounted on an Advantech SOM-DB5830 carrier board. The SOM integrates an IQ X7181 EVK SiP containing the Qualcomm X1E80100 SoC and its supporting components. > [...] > > > +&ufs_mem_phy { > > + vdda-phy-supply = <&vreg_l3i_0p8>; > > + vdda-pll-supply = <&vreg_l3e_1p2>; > > + > > + status = "okay"; > > +}; > > + > > +&ufs_mem_hc { > > + reset-gpios = <&tlmm 238 GPIO_ACTIVE_LOW>; > > + > > + vcc-supply = <&vreg_l17b_2p5>; > > + vcc-max-microamp = <1300000>; > > + vccq-supply = <&vreg_l2i_1p2>; > > + vccq-max-microamp = <1200000>; > > + > > + status = "okay"; > > +}; > > Does UFS come stuffed on all such SoMs? yes, UFS is stuffed on all such SoMs. here is the SoM doc. https://advdownload.advantech.com.cn/productfile/PIS/SOM-6820/file/SOM-6820_DS(052925)20250529110758.pdf > > + > > +&usb_1_ss0 { > > + /delete-property/ usb-role-switch; > > + dr_mode = "peripheral"; > > +}; > > + > > +&usb_1_ss1 { > > + /delete-property/ usb-role-switch; > > + dr_mode = "host"; > > +}; > > + > > +&usb_1_ss2 { > > + /delete-property/ usb-role-switch; > > + dr_mode = "host"; > > +}; > > And this sounds like a limitation of the carrier board more than > anything else The SoM is a self-contained, pluggable module, and these USB role configurations are part of its basic functionality. Therefore, I chose to define them in the SoM dtsi, consistent with the USB configuration in hamoa-iot-som.dtsi. Thanks, Yuanjie > Konrad
