Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git next
...to receive a couple new drivers, coh and ppc440spe-adma (raid offload
engine), and a collection of fixes from Guennadi. There are a few more
shdma fixes pending from Guennadi, but the original driver author wanted
a bit more time to review / test, so I'm obliging. These have been in
linux-next for a few releases.
Thanks,
Dan
Anatolij Gustschin (1):
ppc440spe-adma: adds updated ppc440spe adma driver
Guennadi Liakhovetski (4):
sh: DMA driver has to specify its alignment requirements
dmaengine: fix dmatest to verify minimum transfer length and test buffer size
sh: stylistic improvements for the DMA driver
dmaengine: clarify the meaning of the DMA_CTRL_ACK flag
H Hartley Sweeten (1):
iop-adma.c: use resource_size()
Linus Walleij (1):
Add COH 901 318 DMA block driver v5
