[PATCH 0/4] ARM: DRA7-evm: USB host adaptation

Hi,

These patches adds support for USB host on the DRA7-evm board.
The USB host port (USB2) is tested and works fine.

The USB OTG port (USB1) is still not functional in OTG mode as it is missing
ID pin routing and mailbox write. However, you can get just the host mode to
work by explicitely setting this port to "host" mode.

Patches are based on v3.11-rc3 dra7 baseport tree [1], with balbi/next
merged on top and the control-usb multiple instance support [2].

NOTE: It also needs a patch [3] which allows us to operate at lower then
Super Speed mode. This patch is still in transition.

Patches in this series can be obtained from branch
usbhost-dra7-3.11-rc3
