Subject: [PATCH v3 0/4] Describe the cameras in the PinePhone Pro dts

This series adds support for the Pine64 PinePhone Pro's rear and front
cameras in Device Tree.
This is based on some of Ondrej Jirman's patches hosted in his tree at
https://codeberg.org/megi/linux, but I have also fully reviewed and
re-written the code from the RK3399 datasheet, the PinePhone Pro
schematic, and the IMX258-0AQH5 software reference manual.

I have tested these changes on my PinePhone Pro and am able to take
photos from both cameras using libcamera's cam.
