Hi Ambroz

Thanks for the regression report.

I don't have any Orion5x hardware, i only have kirkwood based
machines. So its very hard for me to test these changes.

I've spotted one thing which looks wrong. Please could you test
this. Its not a fix, just a proof i'm on the right track.

In arch/arm/plat-orion/common.c

/*****************************************************************************
 * EHCI
 ****************************************************************************/
static struct orion_ehci_data orion_ehci_data = {
        .phy_version    = EHCI_PHY_NA,
};

change this to 

        .phy_version    = EHCI_PHY_ORION.

and see if the USB works then.

    Thanks
	Andrew
