Merge series "ASoC: Add new module driver for new ASRC" from Shengjiu Wang <shengjiu.wang@nxp.com>: 

Add new module driver for new ASRC in i.MX8MN, several commits
are added for new property fsl,asrc-format

Shengjiu Wang (7):
  ASoC: fsl_asrc: rename asrc_priv to asrc
  ASoC: dt-bindings: fsl_asrc: Add new property fsl,asrc-format
  ASoC: fsl-asoc-card: Support new property fsl,asrc-format
  ASoC: fsl_asrc: Support new property fsl,asrc-format
  ASoC: fsl_asrc: Move common definition to fsl_asrc_common
  ASoC: dt-bindings: fsl_easrc: Add document for EASRC
  ASoC: fsl_easrc: Add EASRC ASoC CPU DAI drivers

changes in v9
- use lowercase for dt example.

changes in v8
- change get_pair_priv_size to pair_priv_size variable

changes in v7
- updated according to Nicoin's comments.
- add get_pair_priv_size to replace PAIR_PRIVATE_SIZE

changes in v6
- updated according to Nicoin's and Rob's comments.

changes in v5
- Add new property fsl,asrc-format, rather than change fsl,asrc-width
  to fsl,asrc-formt.
- code change for above change.

changes in v4
- Add several commit for changing DT binding asrc-width to asrc-format
- rename asrc_priv to asrc

changes in v3
- add new commit "ASoC: fsl_asrc: Change asrc_width to asrc_format"
- modify binding doc to yaml format
- remove fsl_easrc_dma.c, make fsl_asrc_dma.c useable for easrc.

changes in v2
- change i.MX815 to i.MX8MN
- Add changes in Kconfig and Makefile
