src/patches/panda-usb-power.patch

   1 VUSB is a fixed level line and hence have no set_voltage
   2 callback in regulator ops, but has apply_uV set to true.
   3 As a result it fails to register with the regulator core.
   4 Remove setting apply_uV.
   5
   6 Also, assign name to VUSB supply, without which regulator core
   7 fails to find it and assigns the default 'dummy' regulator to
   8 the ehci-omap device.
