ARM: sun4i: dt: Add USB host nodes to hackberry dts (ca78c26c) · Commits · 戴 / test

Add nodes for the usb-phy and ehci- and ohci-usb-host controllers. Based on fex file settings, the fex file also contains a mysterious line: usb_hub_vcc_en_gpio = port:PB09<1><0><default><0> Which also clashes with usbc0, which has: usb_drv_vbus_gpio = port:PB09<1><0><default><0> So if usb does not work properly we need someone with a hackberry to look closer into this.
