Hi Vinod
Here's an attempt to convert the shdma driver to a new method, whereby a
centrally provided filter function is used and the DMA_SLAVE_CONFIG command
is enabled for slave operation. The last patch is an illustration of how
this new method shall be used. If this approach is acceptable, I'll also
convert the remaining shdma user drivers. This patch series goes on top of
my earlier patches to split shdma.c. It might be easier at some point for
you to have me provide you a git tree to pull from.
Chris, this time the mmc patch is not yet to be applied. We first have to
sort out the dmaengine API.
Guennadi Liakhovetski (4):
dmaengine: shdma: prepare to stop using struct dma_chan::private
dma: sh: use an integer slave ID to improve API compatibility
dma: sh: provide a migration path for slave drivers to stop using
.private
mmc: sh_mmcif: switch to the new DMA channel allocation and
configuration
