Hi Anand,

sorry for the late reply
I have three very small comments below, apart from these, this is looking good!

I would phrase this last sentence as:
"enable USB VBUS on the Micro-USB port using an active high signal"
My idea here is to 1) clarify that it's about enabling USB VBUS only
on the Micro-USB port and 2) use "active high" like the changes inside
the patch itself

I don't think that we should make any VCC3V3 regulator changes in this patch
so please keep this empty line as-is.


Best regards,
