Hmm I guess we could try to get this out of the way to cut down the dependencies. Let's if maintainers of the other affected drivers this is OK for the -rc series.

It seems that nobody needs these until for v3.8, so I'll be applying this into omap-for-v3.8/cleanup-headers-prepare branch soon. Anybody else care to ack?

OK pushed out now with just that patch in the branch in case driver branches need to merge it in too to avoid conflicts.

Drivers should not use cpu_is_omap or cpu_class_is_omap macros, they should be private to the platform init code. And we'll be removing plat/cpu.h and only have a private soc.h for the arch/arm/*omap* code. This patch is intended as preparation for the core omap changes and removes the need to include plat/cpu.h from several drivers. This is needed for the ARM common zImage support. These changes are OK to do because: - omap-rng.c and hsmmc.c don't need plat/cpu.h - omap-aes.c and omap-sham.c get the proper platform_data passed to them so they don't need extra checks in the driver - omap-dma.c and omap-pcm.c can test the arch locally as omap1 and omap2 cannot be compiled together because of conflicting compiler flags Cc: Deepak Saxena <dsaxena@plexity.net> Cc: Matt Mackall <mpm@selenic.com> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: David S.
