However, ads7846 has regressed and it has been broken on 770 for a couple years already as half-duplex support got suddenly deleted without any pre-warning to users (770 was using this driver maybe a decade without any issues). I reported this as a regression but input maintainers preferred to prioritize "nicer hardware". See e.g.: https://marc.info/?l=linux-input&m=164783764828520&w=2 I'm planning to restore the half-duplex support for 770, but it's not on my top prioriority list so it will take a while. Meanwhile, maybe you can ask the users of such "nicer hardware" to test. A.
