ARM: OMAP: devices: create device for usb part of control module
Browse files Browse the repository at this point in the history
A seperate driver has been added to handle the usb part of control
module. A device for the above driver is created here, using the register
address information to be used by the driver for powering on the PHY and
for writing to the mailbox.
