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

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.
