Hi Andy, Your patch does a bit more than reverting commit ecb89f2f5f3e. I will split it in order to see well which previous patches have been reverted.

It would be great to not keep code which becomes architecture dependant. If we can move the filter function somewhere in arch/avr32, we will have to revert commit fda1b26 and use dma_request_slave_channel_compat. I had a look to the arch/avr32 directory but I don't know where to put this kind of stuff. > > It might be a good idea, but I'm neither an expert in avr32 nor have > time right now to do this better.
