Hi,
On dra7 family we have two DMA engine available: sDMA (omap-dma) and eDMA. For some peripherals the use of eDMA is better due to L3 interconnect limitation when using sDMA. Such peripherals are McASP1/2/3. By switching to eDMA we can enable the AFIFO which will help to avoid under or overruns in audio.
This set will: - add the hwmod data for eDMA TPCC and TPTCs - add the needed DT nodes for eDMA and the crossbar - we will enable the AFIFO use for audio - add hwmod data and DT nodes for all McASP ports - Fix the beagle-x15's clkout2 parent setting for the codec
The patch set has been tested on top of linux-next.
