I am concerned that we are putting workaroud for a single controller
into common function. Can we quirk it based on compatible? If not then I
would like someone to run tests on other controllers. Unfortunately I do
not have such hardware.

Linus, do you have devices with ads7846 or tsc2046 by chance? Spitz?

Sadly I do not, but it is inside the Nokia770 so maybe Aaro can test it?
(Not sure if Aaro has the 770 though...)

I sure have 770, and I can test patches.

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.
