Hi Ryan,

Ok.  Denys and I were discussing this and we have a few changes for this patch series that we would like to see.
1) This can move to meta-ti-bsp so that is easier to get into users' hands. 2) When it moves to meta-ti-bsp move it into a dynamic-layer for multimedia-layer and add multimedia-layer to the LAYERRECOMMENDS_meta-ti-bsp set of layers. 3) Make sure to layer the changes into multiple patches and not just glob them all into one. 
  a) Create the dynamic layer directory and update layer.conf
  b) Add the pipewire bbappend (the current patch) to the dynamic layer directory. 

I think that will be cleanest formation for this.

Do all that for a v2 please.
There is one small issue. An empty multimedia-layer directory will not be tracked by git. Either i will have squash into one commit or only add layer.conf in first patch.

Extend the PipeWire recipe to add platform-specific ALSA configuration.
Add sink and source configuration for 8-channel audio playback and
capture on the AM62D2EVM as the default configuration is 2-channel.
