Thanks for providing context. What we miss here still, is the
description of the hardware and for what this syscon is used. Why this
become system controller and before was not? Or this is just for regmap
- then it does not work that way... You cannot have whatever driver
poking all around then claim - I have crappy driver poking to every
driver without implementing proper driver model, so I add syscon to
bindings.



Best regards,
Krzysztof
