Subject: [GIT] dmaengine update for 2.6.39
Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git next
...to receive:
1/ updates to ste_dma40, dw_dmac and fsldma
2/ A new mxs-dma driver
3/ minor updates and fixes to dmatest and pch_dma
Most of this has been in next for while, the few bits that have not
(fsldma update and a couple fixes) pass my local build test.
The most prominent change from a process perspective is that Vinod Koul
has taken over maintenance of the slave-dma usage model. I expect that
slave-dma (peripheral to host dma) will continue to grow as the
predominant usage model for the dmaengine interface. You might start to
see pull requests from him directly in the coming release cycles.
Thanks,
Dan
