    arm64: dts: meson: odroid-c2: Disable usb_otg bus to avoid power failed warning · 72c9b5f6
    Anand Moon authored
    usb_otg bus needs to get initialize from the u-boot to be configured
    to used as power source to SBC or usb otg port will get configured
    as host device. Right now this support is missing in the u-boot and
    phy driver so to avoid power failed warning, we would disable this
    feature  until proper fix is found.
