--- Comment #3 from Christian König <deathsimple at vodafone.de> ---
Not really.

You could do large lists of which registers are save for accessing, but we have
256KB register space and need an individual list for pretty much every hardware
generation.

Sorry but just accessing random registers through the debugfs interface is
simply not expected to work.
