V6/V7 and the earlier V4/V5 are normally mutually exclusive, but we sometimes
screw up the dependencies for some platform, in which case you can end up
with a config that includes both and gives the above error. I'll have a look.
I thought I'd fixed all the bugs we introduced in the merge window in
yesterday's
fixes branch.
There is one known problem for mach-realview in this area, for which
I have a fix.

DAX support was merged with 'depends on !(ARM || MIPS || SPARC)', so I don't
see how this could happen.

Something wrong in arch/sh/include/asm/gpio.h? the codec is only
selectable when gpiolib is enabled, but the consumer.h header
apparently does not get included here.

asm9260 is arm-specific, we probably need to refine the dependencies here
to ensure that OF_ADDRESS is set. Need to think about what the best set of
dependencies is.
