2013-10-11staging: octeon-usb: use a single .h fileAaro Koskinen
Merge USBC and USBN register definitions into a single header file. Although all HW definitions are purely internal to the driver, it's better to keep them separate due to the large size of the file.

2013-10-06staging: octeon-usb: eliminate cvmx_usb_internal_stateAaro Koskinen
Eliminate cvmx_usb_internal_state, just use cvmx_usb_state everywhere. This also enables to allocate only the needed amount of data for the USB internal state, instead of always allocating 64 KB. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-10-06staging: octeon-usb: merge cvmx-usb into octeon-hcdAaro Koskinen
cvmx-usb module provided Cavium "OS abstraction layer" for USB functionality. To make this driver a proper Linux driver, we need to refactor this layer out.
