This is very bad karma, why is the regulator optional?
The platform can provide it's own vbus control in which case this is
not needed.
So why is there no interaction with this external VBUS control and how
does the driver distinguish between that and an error getting the
regulator?
The platform specifies if it provides its own VBUS control by the dt
property ti,no_control_vbus. So the driver will give an error only when
*ti,no_control_vbus* is not set. Graeme?
Thanks
