Applied all patches and pushed to branch v3.16/edma of:

git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci.git

Since the patches did not apply cleanly, please verify. I tested on
DA850 EVM using MMC/SD as EDMA user.

I will wait to get acks from DT maintainers before sending to ARM-SoC.

Thanks,
Sekhar
