Yeah, mentioning clk_ignore_unused/pd is redundant here.

And this repeats the first paragraph.

I do not see how you implemented my feedback, at all. Nothing from it.

I even provided you final clarifications. What is the point of asking me
for the third time, again, what should you do, if you just ignore it?

1. What the DTS is doing here?
2. How did you address "with explanation why this is a fix thus why this
should go to current cycle." - where is this part?
3. Where is Eliza and Milos?

I was repeating the last 2 points multiple times already.

Best regards,
Krzysztof
