What is the name (and the label) for the VBus regulator for the first
connector? It's visible just under your chunk. Why your chunk doesn't
use a similar name?

Hi Dmitry,

As per Bjorn previous comment on v2 patch, "use supply name as per
schematics" so that's the reason I followed that and created a label
as per regulator name.
For eg:- if the regulator name is vmmc_sdc then label vmmc_sdc:
regulator-vmmc-sdc.
In my case the regulator name in schematics is usb2_vbus, then the
label I used is usb2_vbus: regulator-usb2-vbus .

Regards,
Swati

Then please add a commit, bringing the other VBUS supply into the shape.
It doesn't look correct to have two VBUS supplies, which are defined
differently.
