Strange. The base of this series was Heiko's for-next tree from
Friday. No RK3588 EVB1 patches landed since then:

https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/commit/?h=for-next&id=cabb6811c38a46337d5f4252b4dc390f9296856c

If your board uses the original Rockchip bootloader, which shows a
Rockchip logo on the panel, you also need Cristian's latest YUV420
patches that reset VOP2 at probe time avoiding some issues with the
pre-initialized panel as a side effect. Those were recently applied
by Heiko to the DRM tree, so testing on linux-next is indeed
sensible.

Greetings,
