Infinitive loop [drm:vc4_dsi_irq_handler] *ERROR* DSI1: LP0 contention error with 5.15 kernels

[Kuzma30]

Display works on 5.10 kernel (thus my hardware is working), but when switch to 5.15 I get infinitive loop of error
[drm:vc4_dsi_irq_handler] ERROR DSI1: LP0 contention error

Do you test it with kernels > 5.10?

It needs a commit equivalent to raspberrypi/linux@77ef4c1 to request the DSI host to be initialised before the panel. I thought it had been done, but I haven't tested that panel for ages.

If you have an issue with the standard Pi kernel, then it's generally best to create an issue at https://github.com/raspberrypi/linux/issues rather than the hardware repo. I've only passed through for unrelated reasons.
