[libcamera-devel] Kernel to use for PinePhone Pro

[Robert Mader]

Distros like Arch (ALARM) and Manjaro ship Megis kernel, which AFAIK still carries some helpful downstream patches. Notably correct rotation values in the DT are not yet upstream IIRC.

Like Kieran, I don't have a PPP, so my awareness of what is missing in
mainline to properly support the device is limited.

On the camera side, the RK3399 ISP, as well as the front and back
sensors, should be supported in the mainline kernel. Display support has
been merged at the beginning of this year (thanks to great work by
Javier, see
