That is correct. We did not provide final comments on the list so they
could be added here - in change log. This would also be an explanation
why there is a resend. Another solution would be to extend the commit #7
description - why only CMU case is covered.

About patch #7: The decision was not to correct non-CMU case because
there were not actual reports about clock rounding poblems, it would not
be trivial change and we do not have the HW to test.

Thanks Mark for looking into it.

Best regards,
