You could also add the regulator-boot-on to regulator-usb-vbus. If it is
already enabled by the
bootloader, regulator-boot-on will keep it enabled. Otherwise it should cause
the regulator to be
enabled (GPIO set low in this case) when the driver probes.
You could also add regulator-always-on to regulator-usb-vbus, in which case the
USB port can't be
powered down anymore (from userspace). Is there any specific reason you would
want to power the port
down?
Best,
Sander
