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.

Why aren't you enabling the TypeC node and providing a complete example?

Hi Rob,

I have another patch series which enables the type C node and adds QMP
PHY driver changes for setting the SS lane select MUX.

https://patchwork.kernel.org/project/linux-arm-msm/list/?series=361971

Just wanted to work on getting a PMIC based type C driver out there,
which can be utilized in designs where the QMP PHY lane select mux is
not going to be used. (ie using a FUSB340 as a lane select mux instead
of the QMP PHY mux)

Thanks

Regards,
Wesley Cheng
