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

See the previous version of this patchset for further context:
http://www.spinics.net/lists/arm-kernel/msg253342.html
This is a new proposal, in an attempt to fix some obscurities in
the previous MBus DT binding proposal.
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.
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.
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.
As usual, comments and feedback more than welcome. Thanks!
