It would be ideal if I could queue this one, due to the clock dependency.

We need to queue this ASAP and before other patches to fix the build breakage in linux next. Then you can merge in that commit too, does that work for you?

OK cool, will let you know that once we hear from Samuel. Care to ack the clock related changes? There's pm24xx.c at least using osc_ck naming, so I added a new alias to keep it generic for the driver instead of using omap specific names.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) broke compile for non-omap as include plat/cpu.h was added: drivers/mfd/twl-core.c:49:22: fatal error: plat/cpu.h: No such file or directory This header was indirectly included earlier when SPARSE_IRQ was not set, but does not exist on most platforms. Fix the problem by removing the cpu_is_omap usage that should not exist in drivers at all. We can do this by adding proper clock aliases for the twl-core.c drivers, and drop separate handling for cases when clock framework is not available as the behaviour will stay the same. Note that we need to add a platform device to avoid using the i2c provided names that may be different on various omaps.
