Subject is poor. You miss device prefix and it's not correct sentence.

"Add support for XYZ"
or better:
"Add XYZ"

Drop trailing dot

Ditto

You have two resets. Why do you change them to three for all variants?
It's not explained in commit 2/7, so this is confusing.

Thanks. I will change to "Add support for JH7110" in the next version.

Refer to the definition of clocks, define the value of maxItems slightly larger (3),
and reserve a little expandable space without affecting other definitions.
If you need to configure 3 resets in the future, you only need to define it
in individual schemas, and you don't need to adjust this item anymore.  
I will adjust maxItems to 2 in the next version.
