[PATCH] usb: musb: replace hard coded registers with defines

From: Roman Byshko
Date: Mon Nov 10 2014 - 15:53:47 EST


musb registers can be dumped using the file regdump
which is created in debugfs. Up to now hard coded
register addresses are used for that. Different glue
layers however have different register addresses. The
patch addresses this issue by substituting bare register
addresses with defines.
