[PATCH RFC 00/26] Migrate more OMAP DMA code to DMA engine

[Russell King - ARM Linux]

The following patch series moves code to setup the DMA hardware and
service interrupts from the hardware to the DMA engine driver.  This
reduces the dependency on the legacy DMA implementation.

This series does not remove the channel allocation/freeing hooks which
are used to manage the allocation of physical channels - this is the
next step in the evolution.

The patches which move the interrupt handling are currently less than
perfect since they're writing to ENABLE_L0 under a different spinlock,
and hence RFC only at the moment.
