[PATCH v5 00/12] MBus DT binding: A new hope

In the current proposal we have now required a 'controller' property
to specify the MBus controller MMIO registers. To us this looks more
appropriate, since the MBus registers are effectively located within
the internal register region, behind the so-called internal-regs window.

Interesting, seems reasonable to me.

Personally, I can't see any disadvantage, and the binding looks much
cleaner now. But of course I can be wrong, and I'm open to discussion.

There's another pending issue. Arnd Bergmann has required to add a
property to specify the available space within the CPU address space
for decoding windows. This property would allow to support fully
dynamic mbus window allocation.

I wonder if this range is implied - eg it is address space not covered
by the memory node or any mbus ranges? Is there a situation where that
is not sufficient?

For now, this property is intentionally missing, and I expect that
it can be added in the future, together with the full-dynamic MBus
implementation.

@Arnd, @Jason: Given the v4 patchset didn't receive any comments but
wasn't accepted either, I'd like to know which other pending issues
I'm forgetting to address.

I took a quick look and it seems to match what was discussed..

Jason
