OK, assuming the bisectability issues discussed earlier on this thread
are addressed.  I have tested the earlier crossbar patch series in
conjunction with this dts series with VIP capture and DSS display
running together on DRA7.  Looks good with this combination of
devices. VIP is one of the modules that must have a crossbar mapping as
there is no default interrupt mapping for it, therefore VIP makes a good
test case.

So please feel free to add:
