Add the required DTS node for the USB VBUS output regulator, which is
available on PM8150B. This will provide the VBUS source to connected
peripherals.

The device nodes must have the generic names, according to the DT spec.

Hi Sergei,
Thanks for the comment!
DCDC is the label that we use for the DC to DC converter block, since
the VBUS booster will output 5V to the connected devices. Would it make
more sense to have "dc-dc?"
Thanks

You're welcome.

Better use s/th like "regulator-dcdc". As I said, the names should be
generic, reflecting the device class.

At this level it's just a regulator at 0x1100, so it should be
"regulator@1100". If you would like a more useful name in the running
system you should be able to use the "regulator-name" property.

Hi Bjorn,
Thanks for the suggestion. Sounds good, I will just use the "regulator"
name for now.
