[PATCH v2 00/10] ARM: DTS/clk: DRA7 family: enable eDMA and audio updates

Changes since v1:
- hwmod patch for eDMA (tpcc/tptc0/tptc1) removed as it is already in linux-next
- mcasp hwmod changes:
 - all module have HWMOD_OPT_CLKS_NEEDED and no HWMOD_SWSUP_SIDLE (per Paul's
 - mcasp1,2: add ahclkr as opt clock since those modules have fclk, ahclkx and
   ahclkr marked as functional clocks.
   Same change is added to the DTS patch

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.
