    omap3evm: ehci: Update EHCI support on OMAP3EVM (Rev >= E) · e8e51d29
    Ajay Kumar Gupta authored
    Added runtime programming for the differences in EHCI interface between
    OMAP3EVM revisions (Rev >= E) and (Rev < E).
    
    Changes:
    	- EHCI PHY reset GPIO pin is 21 on Rev >= E while Rev < E
    	  uses GPIO pin 135.
    	- Rev >= E uses EHCI Vbus enable GPIO22 line.
    	- Rev >= E uses GPIO61 to select EHCI port either on main board or
    	  on Mistral Daughter Card (MDC). OMAP3EVM Rev < E doesn't have
    	  EHCI port on main board.
    	- Currently GPIO61 it programmed to enable EHCI port on main
    	  board only.
