I agree with this. 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.

Thank you,
