Hi Anand,

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

Add missing usb phy power node for usb node fix below warning.
P5V0 regulator supply input voltage range to USB host controller.
As described in the C1+ schematics, GPIO GPIOAO_5 is used to
enable input power to USB ports, set it to Active Low.
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,
