This is duplicate of "dt-bindings: mfd: rk809: Add audio codec properties"
part of "arm64: dts: rockchip: Add Radxa ROCK 3B" series.

https://lore.kernel.org/all/20240505134120.2828885-3-jonas@kwiboo.se/

A v2 of that series with fixes for reported issues is imminent.
How do you want me to preceded with such v2 series?

Regards,
Jonas
