It's just not what happened. I got this series from Nicolas:

7a1834b ARM: at91: Update struct atmel_nand_data to support PMECC
9356fba ARM: at91/dma: DMA controller registering with DT support
31527e7 ARM: at91/dma: remove platform data from DMA controller
226e3aa ARM: at91: add Atmel ISI and ov2640 support on sam9m10g45 board
e889a64 ARM: at91: add clock selection parameter for at91_add_device_isi()
7a13e73 media i.MX27 camera: Fix field_count handling.
166b37f media i.MX27 camera: add support for YUV420 format.
88c6599 V4L: atmel-isi: add code to enable/disable ISI_MCK clock
... (the rest of v4l at the time)

and I merged it into the next/drivers2 branch, explaining that I would
merge these as soon as the dependencies in v4l are merged. :(

Ok, thanks for the confirmation.

I think it's better for you to just send everything you have right away,
including the atmel-isi patch.

I'll drop the remaining atmel patches from my next/drivers2 branch and let
Nicolas send me a new rebased pull request for 3.4. The patches in question
look simple enough, but if the developers can't get a simple dependency right
after discussing it for weeks, I'd rather not take it this time.
