I took some time testing the patch series on my HP ENVY x360 13- ag0005ng with a Ryzen 5 2500U. On my machine the readout of register AMD_P2C_MSG3 (0x1068C) always comes back as zero (0x0) and thusly activestatus will be zero as well. Consequently the bistmask (0x0) will not match any sensor types. I came up with a patch [1] on top of this patch series to add module parameters to be able to statically enable the different sensors. If I load the module with "force_accel=1" I get a working accelerometer HID device and working screen rotation through iio-sensor-proxy. This only works so far, if I boot the kernel with "amd_iommu=off", which seems to be a general issue with this driver [2],[3].
