Merge tag 'ux500-dma40-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/drivers
From Linus Walleij:
This is a set of patches from Lee Jones to start converting
the ux500 to fetch DMA channels from the device tree:
- Full DT support and channel mapping in the DMA40 driver
- Dropping of platform data for migrated devices on the DT
boot path.
