Changes in v8:
binding:
- Add rob's review tag

dts:
- Add fixed patch to fix sai0 lpcg index
- Update other node lpcg index
- Remove extra space after =
- Link to v7: https://lore.kernel.org/r/20240318-asrc_8qxp-v7-0-01ce5264a761@nxp.com

- Drop conor acked tag form dma-names and interrupt patches
- Fixed warning for interrupts
- Pass dt_bindng check

- Pass DTB_CHECK, below warning exist because binding doc still be txt.

- Link to v6: https://lore.kernel.org/r/20240308-asrc_8qxp-v6-0-e08f6d030e09@nxp.com

Changes in v6:
- Add interrupt description in binding doc according to rob suggestion
- Link to v5: https://lore.kernel.org/r/20240307-asrc_8qxp-v5-0-db363740368d@nxp.com

Changes in v5:
- using rob's suggest logic after fix maxItems.
- sort dts nodes.
- remove spdif1. Add later when do 8qm upstream
- Link to v4: https://lore.kernel.org/r/20240305-asrc_8qxp-v4-0-c61b98046591@nxp.com

Changes in v4:
Combine comments' from v2 and v3. I hope I address everythings.

- Krzysztof's comments
  - add reson about why change

- rob's comments
  using rob's suggest logic to restrict interrupt number
  but for dma-names, still need use oneOf to cover 3 case
  - [rx, tx]
  - [rx]
  - [tx]

  oneOf
    - items:
        - tx
        - rx
    - enums: [rx, tx]

- Conor's comments
  - add power-domains required for imx8qxp and imx8qm
  - remove dmas descript, not allow use index to get dma-channel. Current
no user using this method.

- Link to v3: https://lore.kernel.org/r/20240228-asrc_8qxp-v3-0-d4d5935fd3aa@nxp.com

Changes in v3:
- Fixed dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/sound/fsl,spdif.example.dtb: spdif@...4000: interrupts: [[0, 52, 4]] is too short
