On the original i2s block the channel mapping and selection were configured for stereo audio by default: This is not the case with the newer SoCs and they are also located at different offsets.
To support the newer SoC then regmap fields have been added to the quirks and these are initialised to their correct settings during probing.

That's much better. Thanks!
