sys_proto uses mxs_register_32 so
include <asm/imx-common/regs-common.h>
like arch-mx6/sys_proto.h does.
This prevents warnings when building m28evk after
the next patch in the series.

sys_proto uses mxs_register_32 so
include <asm/imx-common/regs-common.h>
like arch-mx6/sys_proto.h does.
This prevents warnings when building m28evk after
the next patch in the series.

Only perform one copy, either in the bounce
routine for IN transfers, or the debounce
rtn for OUT transfer.
On out transfers, only copy the number
of bytes received from the bounce buffer

Make sure the transfer descriptor is flushed
before the queue is updated so that the controller
