[GIT PULL] ux500 DMA40 device tree migration base

[Linus Walleij]

Hi ARM SoC folks,

here is a patch set that Lee has been chiseling out recently. I've
accumulated it in my ux500 tree and piled ACKs on the first 36
patches of the patch set. Basically that includes ACKs from
subsystem maintainers Vinod Koul and Herbert Xu for affected
parts.

We need to get this into Linux-next to proceed with further
migration on top of it. All have been circulated on the lists for
a while.

Please pull this into an apropriate ARM SoC branch for v3.11!

If we can get ACKs for the rest of the patches in Lee's set these
will arrive on top of this base as soon as they are ready.

Yours,
Linus Walleij

  ARM: ux500: Register Cryp and Hash platform drivers on Snowball
(2013-05-23 21:14:25 +0200)

----------------------------------------------------------------
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.
