Looking at the diff output with and without, it seems to be that the
DMA channels won't get configured.

That should work since DMA engine changes are in mainline and the
DMA channel information is already in DT.

 The issue is that mmc, spi drivers try to get the 'dma' request number from
 get_platform_resource, which fails if hwmod has not populated the data.

 There are patches  already from Balaji [1] for hsmmc, Matt Porter [2] mcspi
 for adapting the drivers for Dma engine. Dma engine gets the data from DT.

      [2] http://www.spinics.net/lists/linux-omap/msg87634.html

       [1] is already in  mmc-next for 3.10 branch.

  Then one more patch for spi [3] is required for completing this. This is similar
   to the patch done for mmc to skip the get_platform_resource call in case of DT.

OK thanks for looking into that. Once those driver changes hit
mainline, please send a follow-up patch to remove the spi and
mmc entries.
