Warnings from u9500 device trees

[Olof Johansson]

Known issue? I haven't seen a patch for it on the lists yet.

Warning (reg_format): "reg" property in

prcmu has #address-cells of 1, and #size-cells of 1, but the reg is
just a single cell on that entry (<5>). Something's weird with either
the binding you've implemented, or how you specified the device tree.

The changes are old too, since March. No one else has noticed this
since then? Are there no users of this platform? :(

Neither. We've known about it since March (including Arnd), but it's
not important. The issue is that #size-cells can't be 0, but the 
AB8500 uses mailboxes not registers, so there is no size per-say. I
have requested that we remove the 'reg' property entirely, as the
Mailbox number is hard-coded, but Arnd wasn't a fan, so we just left
it as-is.

Out of interest, why are you getting 4 errors? Are you building all
of the DTS:es at once?

Kind regards,
Lee
