Subject: [GIT PULL] slave-dmaengine updates
Hi Linus,
Here is the slave-dmaengine updates.
This is fairly big pull by my standards as I had missed last merge window.
So we have the support for device tree for slave-dmaengine, large updates to
dw_dmac driver from Andy for reusing on different architectures. Along with this
we have fixes on bunch of the drivers
Thanks
~Vinod
