Why this tag stayed and other was removed? What was the reason of tag
removal?

Driver does not use or hardware supports only one frequency?

Were these the reasons?

I am really surprised that after 11 versions this binding still is being
totally reshaped and you need us to re-review.

Also, start using b4 tool, so:
1. your cover letter will have proper links to previous versions
2. b4 diff would work. Look, try by yourself:



b4 diff '<20241125092146.1561901-3-yuji2.ishikawa@toshiba.co.jp>'

How can I verify what happened here without too much effort?

Since you ask for re-review, then:
