V2: - Add AUDIO_AXI clock to audio gpc
- Use IMX8MP_CLK_AUDIOMIX_SDMA2_ROOT for SDMA2 IPG clock
V3: Rename audio_ahb to plain ahb
V4: - Add RB/TB from Luca
- Rebase on next 20230223
V5: - Add TB from Adam and Alexander
- Replace blk-ctrl@ with clock-controller@
- Specify sound-dai-cells in sai nodes
V6: - Add RB from Fabio
- Drop power-domain-names from audiomix block/clock controller
- Move reg below compatible property
- Move sound-dai-cells below reg property
- Sort DT properties: compatible, regs, #cells, properties, status
V7: - Move #clock-cells below reg property
- Add AB from Peng
- Add RB from Marco, sort the tags
V8: Add TB from Richard
