[PATCH v2 00/16] ARM: support for ICP DAS LP-8x4x (with dts)

[Sergei Ianovich]

Fixed most review requirements. Details in respective patches.

I've completely met the requirement for using dmaengine-based DMA
in patch v2-03/16. Tests showed new DMA was underperforming. It added
on top of a pre-existing problem with MMC bus width and made the system
barely usable. However, the new code in this patch work correctly with
both the existing and the new DMA. Even if the new DMA is compiled into
the kernel, the exisitng DMA initializes first.

I've also decided not to create a single mfd device for
machine-specific devices. Instead each type is supported by a separate
driver in respective subsystem. It was tempting to hardcode all the
constants in one source file, but that requires ugly initialization.
The taken way produces much cleaner code.
