Can you please tell me what device you have? Do the patches work for
you?

I have an ILI2117A/ILI2118A.

I'll try out the patches today. I'm stuck with a 4.1 vendor kernel, so
I'll need to backport the (patched) mainline driver to 4.1 before
I'm able to test.

I wil try Marek's patch, and Dmitry's rebased patch from
https://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git/log/?h=ili2xxx-touchscreen
and let you know the results.

For what it's worth, I tried the 3-patch series from that branch on
5.4-RC5, but the ts_calibrate and ts_test_mt do not appear to receive
touch info.  They execute when I 'export
TSLIB_TSDEVICE=/dev/input/event0' but I don't get touch data.

If I do a hex-dump of /dev/event0 and it dumps data if and only if I
hold my finger on the touch screen for a while.

I'll try just doing the 1st patch to see if it it's any better.

If the problem with Dmitry's patch is located in ili251x_read_touch_data,
then using a ILI2117A should work fine.
