Hi Jakob,
the change itself looks ok, but there are some logistic changes needed.
For one, please drop the local TSD prefix from patches submitted upstream.
The patch subject should be something like
arm64: dts: rockchip: use codec as clock master on px30-ringneck

As sender of the patch you need to add another Signed-off-by line
of your own. With this you indicate that you were allowed to submit
the patch. So this needs two SOB-lines, one for Ermin as the original
author and one for you as the submitter.
Probably same for the second patch.
Thanks
Heiko
