How do you rotate the touch? I need to invert the screen but the touch still follows the "upside down" method in desktop. I have pi 5 running 64 bit bookworm.

I got the screen working with a simple
dtoverlay=vc4-kms-dpi-hyperpixel4sq
dtparam=rotate=180 didn't seem to do the trick.

Im able to get the screen rotated, and the correct x motion, but dtoverlay=vc4-kms-dpi-hyperpixel4sq,rotate=180,touchscreen-inverted-x,touchscreen-inverted-y doesn't seem to affect the Y motion.
