Including stuff from <mach/..> isn't really compatible with
MULTIPLATFORM, so please don't write new code like this. Actually we
don't want any code under drivers/ to include stuff from the mach
directory.

I suggest that you arrange your code in a way so the C version of DMAC
support has tables with slave ids as usual under
arch/arm/mach-shmobile/, but the DT bits that operate independently of
C stay in drivers/... Over time we will get rid of the C version, and
until that happens the DT and C version can coexist in parallel.

Cheers,
