No. Actually I don’t want PMIC to enable it by default. I want the palmas-usb
driver to handle it.
Enabling it by default makes palmas-usb to detect VBUS interrupt. This should
ideally be detected only when you connect a host cable.
Btw I didn't exactly get why you want regulator-boot-on should be kept here.

Thanks
