Ok, so maybe there is a different way of doing this: If I understood it correctly, we now lost the debugfs handling on all syscon nodes?
Should we try to come up with a way to bring it back for all of them then, rather than having to do it per device?
I can see two possible ways of doing that:
a) change the regmap code to provide a debugfs interface for all regmaps, including those without a device b) change the syscon driver to explicitly register the debugfs interface at a later point in boot when the devices become available
