This patch set will enable generic functions for controlling
slave transfers, e.g. the ability to pause and resume transfers,
as well as the ability to read a wider status including not only
the current and last transfer cookie but also the residual
bytes left on a channel.
This was discussed by Dan and Guennadi some while back and now
I implemented it.
I did my best to read my own code over and over again so I
didn't break anything, but please review again.
I need help: does someone have a list of defconfigs I need to
compile to compile-check the entire DMA engine subsystem?
I guess I will need a number of cross compilers as well, this
is a bit hairy but will probably help out in future refactoring
as well if I can get them to fly.

I can check this out with my dmaengine build system. I have attached
the script and the defconfigs that I use. Yes, it does require a small
arsenal of cross-compilers.

OK, that would be much appreciated because when I look at that
build system I see it will take some time for me to get such
a beast up and running...
Yours,
