Sorry for digging up an old thread. The board-compatible change is now
I think merged into ath12k, but I'm not sure I like that, as now every
OS consuming this DT has to carry a table of board compatibles (hence
needing updates _every single time_ we want to support a new device),
instead of being able to convey the quirk through the property

Perhaps we could revisit this approach?
