If anyone is looking for a great guide on mainlining a device of their own, I can greatly recommend

https://mainlining.dev/

Thanks a lot! :)

Seems to be only for OnePlus Nord

> We finally shipped sensors on SDM845, only to discover that the OnePlus 6T accelerometer was upside down

How does this happen, anyway? What does “upside-down” mean? Is there really a standard for these things in the first place? The systemd udev database is chock full of accelerometer matrix remappings.

I’ve submitted patches to udev’s accelerometer mount matrix for cheap 2-in-1 laptop/tablets before. I think I’ve actually had to poke at that for three completely different laptops before
