Subject: [PATCH v4 0/4] Upstreaming Pinephone Pro Patches

Throughout the years, many have contributed to the Pinephone Pro (ppp)
development. Unfortunately, these patches are scattered around various
repositories in different states.

I will be attempting to upstream these patches. I will start off with the
following small series:
- Add light/proximity sensor support
  - Link: https://codeberg.org/megi/linux/commit/f171bc7013bc7ad3de9af817bfbcbfa548ebe01c
- Add accelerometer sensor support
  - Link: https://codeberg.org/megi/linux/commit/b0bb7633e073a6760fa213b8c4a78ea2e73c7bf1
- Add magnetometer sensor support
  - Link: https://codeberg.org/megi/linux/commit/2f7e67f451f16eaf15b81aa1dbdf126d54927d35
- Add mount-matrix for magnetometer
  - Link: https://codeberg.org/megi/linux/commit/d7cd2eab931e32fa94408a96d73b4e6c0616107a
- Fix voltage threshold for volume down key
  - Link: https://codeberg.org/megi/linux/commit/7c496a5cc27ed4e38b740f36c2d8b2c62f80ae54

Unfortunately, because most of userspace (plasma, phosh, kompass,
hwtest, etc.) use the ppp's downstream kernel as a reference, the
incorrect mount matrix for accelerometer and magnetometer have
propogated to userspace, and therefore we can't use them for testing as
they will give the wrong result. Instead, we have to read the raw values
from the device and compare it to
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/iio/mount-matrix.txt#L80-L90
as that will lead to the correct result

I would request reviewers to look at the mount-matrix tests and help me
see if they make sense. I've read the mount-matrix documentation, but it
isn't really clear to me if the values in the tests are the values I
should be getting
