Touch screen rotation
After a lot of trial and error I managed to get my Pi4B up and running with a Waveshare HDMI 7.9 widescreen display... but two sticking points I'd like some help with if anyone has any ideas:
It won't boot at all without changing dtoverlay=vc4-kms-v3d,cma-384
todtoverlay=vc4-fkms-v3d,cma-384
in the config.txt, but this gets reset after a reboot it seems. Is there some way to alter this in the config-overrides.txt?
Secondly - the touch detection is 180 degrees off from the screen. I've tried display_rotate=2 etc but no luck. Is there a solution for this?
Thanks in advance for any help.

@Jon Better to set fkms through property: setprop persist.rpi.vc4.force fkms

Not sure about the touch rotation, more of a waveshare question
