I dropped this patch series from my queue due to sashiko's replies. I
just notice these were not sent to the linux-pwm list, otherwise I would
have mentioned it. :-(

So check on either

	https://lore.kernel.org/all/add09636-7b0e-4a99-8503-d98a75c14f4c@xxxxxxxxxx/

or

	https://sashiko.dev/#/patchset/20260529-t264-pwm-v5-0-7bf9e405a96a%40nvidia.com

.

I only invested a quick glance, but the feedback seems relevant. If you
don't agree, please point out why it's wrong/irrelevant.

Best regards
Uwe
