Though, flexcom documentation is subject to YAML conversion (a patch has been re-posted these days [1] and *maybe* it will be integrated this time). And there are multiple SoC DTs that need to be updated with their own flexcom compatible (lan966x, sam9x60, sama7g5). To avoid conflicting with the work at [1] and postponing this series we may do the update after the [1] is done. Let me know your thoughts. Either way is fine by me.
