[PATCH v2 0/6] ARM: DT/davinci: Audio for da850-evm in DT boot

[Peter Ujfalusi]

Hi,

Changes since v1:
- fixed the address missmatch for tlv320aic3106 codec (@1b -> 18)
- The edma patches has been taken by Vinod, they should be in linux-next soon.

The following series will enable audio via simple card on the board when booted
with DT.

For edma one patch is needed to have working dma:

I assume all of these 6 patches are meant to go through ARM SoC. I have
applied all of them for v3.18.

Also tested audio playback and record on DA850 EVM. Works great!
