There are times when I wonder why I bother replying to email on mailing
lists. No patch ever came from my responses on this subject. Not going
to repeat it again. Fed up.

Before this goes much further... one fairly obvious and important point
must be made.
You're designing an API here. You're designing it *WITHOUT* involving
the two most important people in its design that there are. The
DMA engine maintainers. Is this how we go about designing APIs - behind

These three patches add support for returning the residue and cyclic DMA
support to the OMAP DMA engine driver.
As v3.5-rc is horribly broken on my OMAP platforms, I've had to back out
all the sound/soc/omap changes from the last merge window to test this,

Dan, Vinod,
There's a change I would like to do to the DMA slave configuration.
It's currently a pain to have the source and destination parameters in
the dma_slave_config structure as separate elements; it means when you
want to extract them, you end up with code in DMA engine drivers like:

Can someone please hint on what audio is supported on these two OMAP
boards? From what I can tell, the answer is either "nothing" or "hdmi",
both of which are useless to me if someone wants me to convert the OMAP
ASoC driver to DMA engine.

Here's another patch - for the OMAP NAND driver.
One thing this doesn't do is configure up the source/destination bursts,
which the old code did:
omap_set_dma_dest_burst_mode(info->dma_ch,
OMAP_DMA_DATA_BURST_16);
For the full text, please see

This version contains updates for some of the comments received from the
previous round, and adds the OMAP1/2 MMC and SPI drivers to the conversion.
I've also added a note to feature-remo

Here's a patch which converts the SPI driver to use dma engine support.
It's more or less a mechanical replacement in this driver. Tested on
OMAP4430SDP ethernet (which basically means that udhcpc works.)
One thing to note: the old DMA code programmed the DMA hardware for an
element count of N an

There's no direct scatterlist support on OMAP2 either (omap_

Does this driver make use of this platform data?
If so, it needs converting to DMA engine _before_ this patch (which is
one reason why it

This series is the preliminary conversion of OMAPs private DMA API to
DMAengine. It focuses on the OMAP HSMMC driver, as I believe that is
the only DMA-capable driver which is used on the platforms I have
available (3430LDP and 4430SDP).
For the OMAP DMAengine driver, there's a few short-comings:
