Hello Rob,

Thanks for your review and reminder.

Moudy's mail is still not received by devicetree at vger.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,
Rex
