Since the last and the only user of this driver is converted to use dw_dmac we
can remove driver from the tree.
Moreover, besides the driver is unmaintained a long time, it serves for the
DesignWare DMA IP, for which we have already driver in the tree.

Every DMA engine implementation declares a last completed dma cookie
in their private dma channel structures. This is pointless, and
forces driver specific code. Move this out into the common dma_chan
structure.

For a very high speed DMA various periphral devices need
scatter-gather list support. The DMA hardware support link list items.
This list can be circular also (adding new flag DMA_PREP_CIRCULAR_LIST)
Right now this flag is in driver header and should be moved to
dmaengine header file eventually

This patch adds runtime PM support in this dma driver
for 4 PCI Controllers
Whenever the driver is idle (no channels grabbed), it
can go to low power state
It also adds the PCI suspend and resume support

This patch add DMA drivers for DMA controllers in Langwell chipset
of Intel(R) Moorestown platform and DMA controllers in Penwell of
Intel(R) Medfield platfrom
This patch adds support for Moorestown DMAC1 and DMAC2 controllers.
It also add support for Medfiled GP DMA and DMAC1 controllers.
These controllers supports memory to peripheral and peripheral to
memory transfers. It support only single block transfers.
This driver is based on Kernel DMA engine
Anyone who wishes to use this controller should use DMA engine APIs
This controller exposes DMA_SLAVE capabilities and notifies the client drivers
of DMA transaction completion
Config option required to be enabled CONFIG_INTEL_MID_DMAC=y
