To resolve the above issue, we have made "PHY power on" in battery
adc on function
and "PHY power down" in battery adc off function.
Good news, the temperature is bad value from battery adc if otg phy is power
down. Maybe you only need to power on otg phy before reading battery adc, then
power down otg phy after the reading if no usb calbe is connected with musb
for decreasing power consumption. (I am not familiar with battery adc, just
for your refrerence)
I think you only need the usb3v1 regulator. And it can even be in sleep
mode, it doens't have to be on. What I would suggest is that usb3v1
never to be turned off, only put in sleep mode.
