V2: No change
V3: No change
V4: - Update codec node name and phandle label
- Use just sound for the sound node name
- Rebase on next 20230223
V5: - Drop regulator-always-on from codec regulator
- Add RB from Fabio
- TB by Alexander added and removed again, since the patch was reworked
- Switch to simple-audio-card
- Add sound-dai-cells to codec node
V6: - Split off separate pinctrl for regulator
- Drop unused SAI3_RXFS pinmux
