Subject: [PATCH 00/15] ARM: pxa: switch to DMA slave maps

Hi,

This serie is aimed at removing the dmaengine slave compat use, and transfer
knowledge of the DMA requestors into architecture code.

This was discussed/advised by Arnd a couple of years back, it's almost time.

The serie is divided in 3 phasees :
 - phase 1 : patch 1/15 and patch 2/15
   => this is the preparation work
 - phase 2 : patches 3/15 .. 10/15
   => this is the switch of all the drivers
   => this one will require either an Ack of the maintainers or be taken by them
      once phase 1 is merged
 - phase 3 : patches 11/15
   => this is the last part, cleanup and removal of export of the DMA filter
      function

As this looks like a patch bomb, each maintainer expressing for his tree either
an Ack or "I want to take through my tree" will be spared in the next iterations
of this serie.

Several of these changes have been tested on actual hardware, including :
 - pxamci
 - pxa_camera
 - smc*
 - ASoC and SSP

Happy review.
