It's fairly overkill though ... we don't really plan to expose much of these things to Linux anyway, it's mostly buried in firmware, I just want scom access to userspace for debug/diagnostics. I don't want it in debugfs however because we might want some "health monitoring" daemon running in userspace that uses it to check some of the built-in CE statistics etc... in the various chips and handle some of the repair work. I prefer having that stuff in userspace (it's fairly complex) than in firmware but it will get all the data it needs from the device-tree, there's no point trying to reproduce the whole chip hierarchy and sub hierarchy in Linux.
