This way the same driver can be used for the misc SCM registers from other drivers.
Hi, OK, make sense, others driver wont have to patch the base address later on.
If you don't define it that way now, you'll end up with broken child driver offsets in the .dts files later on.
yes, Unless someone changes the base and not the offset, given that all are in one dtsi
