ARM: dts: at91: sama5d2 Xplained: set pin muxing for usb gadget and usb host
For USB gadget on port A (device mode):
- pin PA31 is configured as an input GPIO which triggers an interrupt when
vbus is detected on USB port A.
- pin PB9 is configured as an output GPIO and set to low level so the
board doesn't supply vbus to USB port A.
For USB host:
- pin PB10 is configured as an output GPIO and is active at high level.
The ohci driver will activate this pin so the board supplies vbus to USB
port B.
- pin PB9 should be configured as an output GPIO and active at high level
to use to USB port A in host mode (conflicts with USB gadget).
