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
