   4 Subject: [PATCH] ARM: sun4i: dt: Add USB host nodes to hackberry dts
   5
   6 Add nodes for the usb-phy and ehci- and ohci-usb-host controllers.
   7
   8 Based on fex file settings, the fex file also contains a mysterious line:
   9 usb_hub_vcc_en_gpio = port:PB09<1><0><default><0>
  10
  11 Which also clashes with usbc0, which has:
  12 usb_drv_vbus_gpio = port:PB09<1><0><default><0>
  13
  14 So if usb does not work properly we need someone with a hackberry to look
  15 closer into this.
