Commit Message

Elinor Montmasson Dec. 15, 2023, 2:40 p.m. UTC 
Add new optional dts properties "cpu-sysclk-dir-out" to set
sysclk directions as "out" for the CPU DAI when using the generic codec.
This can be set for Tx and Rx.
If not set, the direction is "in".
The way values are used is up to the CPU DAI driver implementation.
