Hello Laszlo,
Since you have a RK3588 based board, sending a Tested-by
tag on testing patches 1-2 makes sense.
However, patches 3-4 are for Qualcomm based boards.
I'm not sure if you also have a Qualcomm board at your disposal.
If you don't, Manivannan can probably drop your Tested-by tags
on patches 3-4, but it might be good to know until next time.
Thank you for testing!
Kind regards,
Niklas
