Only after finishing the review, I've noticed that I just wrote the same things
that I wrote in my review for version 8... and if I recall correctly, this is not
the first time that something like that happens.
Please pay attention to what reviewers say, as to not waste anyone's time.

This looks way better:
hsync.sync_width = vm.hsync_len;
hsync.back_porch = vm.hback_porch;
hsync.front_porch = vm.hfront_porch;

Removing this line is not part of adding dpintf support, so don't do that.

This message is not giving any constantly changing information, nor any one that
is interesting for the user: keep this as dev_dbg().

You're getting this clock twice, what happened here?
P.S.: As I explained on the dt-bindings patch, you likely don't even need this
clock at all.
