My customer will use USB OTG and Host1 in i.MX6DQ.
Refer to "PMU_REG_3P0 field descriptions" in IMX6DQRM(Rev.3).
"VBUS_SEL” bit can select input voltage source for LDO_3P0 from either USB_H1_VBUS or USB_OTG_VBUS.
Is it both need input power of USB_H1_VBUS and USB_OTG_VBUS?
(i.e. If either is inputted, is power supplied to both of Host1 Phy and OTG Phy?)
If good in either input USB_H1_VBUS or USB_OTG_VBUS, Why does two VBUS ports exist?
