The mt pointer emulation should do this for you.

Can you point me to some documentation on that? Do I need to enable this?

Just do

	input_mt_report_pointer_emulation(tsdata->input, true);

That only seems to work when using slots (which I don't do yet and while
I am willing to change it I can't do it right now since other software
depends on the type-a protocol...).

Where would be a proper place to document such device-specific behaviour?

Maybe Documentation/input/...? Thisis hardware-mandated behavior, right?

Yeah, I guess I'll cook up a small document.

Should this GPIO configuration be done by the driver or by the board
code that configures i2c client? I think latter is better.

I got conflicting opinions when I asked for advice on this last december
(before changing it to a pin-based configuration). Why do you think that
your suggestion is better?

Can the device be connected via a pin not plugged into gpio subsystem?
Other than deriving IRQ from it you do not seem to be using it.

Well, I do configure the pin as input as well.

Which would then probably have to move to the board file, where there is
no real good place to put it. Or you invent some sort of callback
functions in the platform device structure so that the driver calls back
into the boardfile.

I dunno. Seems like a lot of overhead for very rare/obscure usecases.

I'll prepare a new version of the patch incorporating the other feedback
from you. Hopefully I'll manage to do this in the next few days.

Bye,
        Simon
