Hello Rob,

Thanks for your review and reminder.

Moudy's mail is still not received by devicetree@...r.kernel.org.
We are still under checking this issue.
To prevent you do not receive his response, I help Moudy to mail you
again.

Moudy will sync the description from the patch listed below to this
property and extend to other yaml files in this series.

BRs,
