FWIW: I've seen this issue as well.

Please try if unreverting that commit and adding the following:
https://lore.kernel.org/linux-rockchip/20240709105428.1176375-1-i@xxxxxx/
fixes the issue as well.
I confirm that 6.10.6 without any reverts plus
20240709105428.1176375-1-i@xxxxxx also fixes the issue.
Thank you all.
Great! Could you, please, provide your Tested-by in the patch thread
linked above? That should help with getting that patch merged upstream.
