The patch doesn't build against rockchip64 6.12 -- and looking at the patch it doesn't affect the RK35XX series at all. To port it, I think I need the max_prate constants for the RK3566 (is this in clk_rk3568.c? or some other file, there isn't a clk_rk3566.c) I think the datasheet (https://www.boardcon.com/download/Rockchip_RK3566_Datasheet_V1.1.pdf) says it's 600MHz for HDMI

After testing it with verbosity=7 on both vendor and current, there's nothing suspicious in the kernel logs -- on vendor, I get: root@radxa-zero3:~# journalctl -k -b 0 | grep -iE

I disassembled my other radxa and swapped the SD cards, and it is just something funny with this hardware. I also just realized I bought a different configuration -- the one that works with `current` is a 2GB RAM version, and the one that has no HDMI (except on `vendor`) is a 4GB RAM version. I wonder if there are hardware differences.

Hm, I found the debs locally and installed them (along with the DTBs), still don't have HDMI. At this point I'd suspect the hardware but the vendor image works.

Digging through my build logs, it seems the last kernel that worked is "linux-image-current-rockchip64_25.05.0-trunk_arm64__6.12.20-Sf491-Da873-Pe64b-C1f18H02eb-HK01ba-Vc222-B9bbb-R448a.deb" -- anyone know how I can rebuild this?

So I have two boards, and two images, both built with armbian-build. I built `current` on March 24th 2025 and HDMI and everything works great I built one this week and there is no HDMI output.
