OMAP3EVM (Rev >= E) has EHCI port on main board itself. Apart from this
there is a slot to connect Mistral Daughter Card (MDC) to it which also
has one EHCI port. Only one EHCI port can be used at a time and we can
choose the port using GPIO61.
These are the new GPIO lines used for different purpose on EHCI interface.
- GPIO21 - EHCI phy reset
- GPIO22 - EHCI VBUS enable
- GPIO61 - Selects EHCI port either on main board or on Mistral
Daughter Card (MDC).
