We have 3 signals for USB : - GPIOH_5: goes to CHIP_EN to CHIPENABLE to the Hub - GPIOH_4: goes to RST_N to RESETJ to the Hub - GPIOH_6: goes to PWREN for the OTG connector PWREN As you said, the datasheet mentions : " Disable whole chip and keep hub in lowest power state (standby mode " I modeled it as a regulator since when enabled it actually enables the power on the USB3 ports using the post-Hub VBUSCTRL signal. Since I can't model these post-hub power enable signals, I can only model the hub CHIPENABLE as a regulator to handle power. I can't model the hub as a device subnode inside the dwc3 since when CHIPENABLE is low, it won't appear... We could model it as a Hog, but we won't be able to power down the usb3 ports. > > [...] >> +&ext_mdio { >> + external_phy: ethernet-phy@0 { >> + /* Realtek RTL8211F (0x001cc916) */ >> + reg = <0>; >> + max-speed = <1000>; >> + eee-broken-1000t; > are we in the same situation that we have on the X96 Max where network > dies without eee-broken-1000t?

You're right, now we have the schematics, it's not the phy supply. I'll move it to vbus-supply since it's connected to the pwrenable of the otg port. > > if these three questions are answered then you can add my: > Reviewed-by: Martin Blumenstingl I'll ask you to review the next version before !!!
