So you just ignored my comment? I did not receive any response from you
on this.

I had mentioned it in the cover letter next to the changelog:

Unadressed feedback from PATCHv1:
- anatop phandle vs parent: technically it makes sense to just use the
parent, but this driver is only used by i.MX6. The current code makes
use of the phandle, so we cannot drop it because of backwards
compatibility. So I don't see a point in deprecating this property.

(reading it again: s/driver/binding/ and s/code/Linux kernel driver/)

Greetings,

-- Sebastian
