I recently rebased all my patches on top of 3.13-rc3, and will resend in
couple of days.

The real problem here is that by reworking the DMA related PXA bits, all
drivers have to be changed at once, and a gradual transition seems
impossible. For that, I was asking for help in areas where I don't have
any hardware to test my patches on, but unfortunately, nobody got back
to me yet.

In particular, the pxa camera driver is something Robert (cc) wanted to
have a look at. Robert, any updates on this?


Anyway, I'll have to clean up some details and will resend my patches
very soon.


Thanks,
Daniel
