I'd rather that were available all the time since it's so useful.

Adding a read interface in debugfs would certainly be sensible, though -
I have in the past considered adding a much more detailed readback
interface to debugfs which would not only dump the registers but also
provide some decode information (eg, reporting the mapping to controls
for the standard ASoC widgets).  Not something I have the time to do in
the immediate future, though.
