In V4, I said remove this VBUS control and my mean was to remove all 
regulator calls for VBUS enabled/disable.
I saw you just remove the platform data option to have this control and 
made VBUS mandatory.

Probably some gap here.

In tegra platform, we dont need VBUS regualtor control from extcon.
