RX11 (N900): Wrong screen axis direction and screen calibration

Created by: dviaznikov

Good day. After installing postmarketOS with XFCE4 on my N900, everything works pretty fine, except my screen.

1. Axes is reversed with no capability to change it via xinput. I've tried to change "TSC2005 Touchscreen" axis reverse via changing xinput props values. Hovewer, I'm not capable to find any axes-related props in there. After some digging, I discovered some recommendations to remove libinput (as strange as it seems), but libinput is required by postmarket.
2. Touchscreen badly calibrated. But I was able to change calibration values to suit my needs via calibration matrix. I am sorry if this issues is not related directly to postmarket, but any help is appreciated. Thanks.
