Hi Mauro

With acks from Hans and Laurent I'd like to ask you to pull my V4L2 clock 
and asynchronous probing APIs together with respective soc-camera changes. 
I included an ack from Laurent, even though he requested me to include the 
documentation update into this pull request, which I haven't done yet. But 
we agreed privately, that it's also ok, if I submit a v2 of the patch 
first to the list next Monday and then send an additional pull request for 
it some time next week. The last patch from the patch series, as I posted 
it to the list last time is also omitted, because (1) it's for arch/arm, 
(2) the board, which I used as an example to develop and test these 
patches will be removed from the kernel, so, I'll need to pick up a 
different platform for testing, also a different camera host driver, 
perhaps.

The following changes since commit 4ef72e347112a834fbd6944565b1f63d4af19c8a:

  [media] V4L2: soc-camera: remove unneeded include path (2013-06-21 13:11:59 -0300)

      sh_mobile_ceu_camera: add asynchronous subdevice probing support
      imx074: support asynchronous probing

and for patch "V4L2: support asynchronous subdevice registration"

Mauro, maybe it would be possible for you to modify only these two 
patches.

Thanks

Ok. Btw, as Tested-by implies on ack, so I'll just add tested-by.
