Oh, that's a bit odd: That would mean that the defaults are also broken on
big-endian platforms, and fixing them would introduce the bug here, unless your

Any idea why musb uses the __raw_* functions to start with? Can we change
them to read?_relaxed()/write?_relaxed() now that those are available on
