It is normal to have something in the changelog, even if it is the
same as the subject said differently.

Here you could say something like:

Commit a095b1c78a35f05755 "ARM: mvebu: sort DT nodes by address"
missed placing the system-controller in the correct order.

Humm.

Now we have things in the right order, we see that the
system-controller and the clock-gating-controller overlap.

I know the HW engineers have gone a bit crazy around here, so maybe we
have no choice?

Hello Andrew,

I guess your question concerning overlapping ranges doesn't stop this
patch from being useful, does it?

Also thanks for the suggested wording which I nearly took as is.

Best regards
Uwe

Not nice indeed. All those "system-level" registers that do not belong
to clearly identified hardware blocks are really a mess. Maybe it's
time to use the 'syscon' infrastructure to deal with those registers?

Unfortunately, due to the major pain caused by DT backward
compatibility, switching completely and properly to syscon is probably
going to be difficult if we don't want to break old Device Tree files.

Best regards,

Thomas

Applied to mvebu/dt with Andrew's Ack.

thx,
