Thanks for the feedback! I might have misunderstood the best approach here. The reason I split the WiFi/BT configuration into separate dtsi files was to follow the direction discussed in the previous revision, where we decided to keep support for the legacy Broadcom-based SOM while moving the configuration out of the device tree, giving the support for both modules revisions. However, I see your point that if it is not referenced anywhere it becomes dead code: Would it make sense to add a legacy Symphony DTS that includes the Broadcom configuration, in addition to the current Symphony DTS that uses the IW61x? This way the existing boards would keep working while the default board description reflects the currently produced hardware. Or if you have any other suggestion, I'd be happy to follow it!
