Merge series "ASoC: ti: Add support for audio on J721e EVM" from Peter Ujfalusi <peter.ujfalusi@ti.com>:

Hi,

Changes since v3:
- Fix the single clock source handling and typo

Changes since v2:
- DT binding:
 - use proper (?) patch subject for the binding docuemtn patch
 - drop pll4 and pll15 from DT - driver should check the rate via
   clk_get_parent. If it is not available (as it is not currently) then use the
   match_data provided rates.
 - add simple explanation for the clocking setup
 - Use descriptive names for clocks: cpb/ivi-mcasp-auxclk and cpb/ivi-codec-scki
 - dt_binding_check shows no errors/warnings
- ASoC machine driver:
 - Try to read the PLL4/15 rate with clk API (parent of the two clock divider)
   if it is not available then use the match_data provided numbers.
 - Support for single PLL setup

Changes since v1:
- Fixed DT binding documentation errors
- Rebased on ASoC head and updated the driver to compile and work

This series adds support for the analog audio setup on the j721e EVM.
The audio setup of the EVM is:
Common Processor Board (CPB): McASP10 <-> pcm3168a
Infotainment Expansion Board (IVI): McASP0 <-> 2x pcm3168a

Both CPB and IVI wired in parallel serializer setup.

The first patch adds the stream_name for McASP driver as it is needed in
multicodec (and would be needed in DPCM) setup for proper DAPM handling.

The second patch adds two DT schema, one for the cpb and one for the cpb+ivi
card.

Regards,
Peter
