I will look into this further. 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/co= mmit/?h=3Dfor-next&id=3Dcabb6811c38a46337d5f4252b4dc390f9296856c 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.
