There is currently two different ways to handle sensors, the Linux way which is taking earth as a starting point and then drawing a vector through the device, as well as the Windows way which takes the device as a starting point and drawing a vector towards earth. iio-sensor-proxy decided to go the Windows way, therefor the configuration needs to be flipped for the readings to produce the expected result. I created an issue with iio-sensor-proxy that goes into a bit more details, see #375. Part-of: <https://gitlab.postmarketos.org/postmarketOS/pmaports/-/merge_requests/7085>
