Invert Y is needed (together with swap XY) for some touchscreens,
at least for some of them :

- CarTft 8in4 (type=eGalax, USB=0eef:0001)
- LeadingTouch

Since there is not guarantee that
those above devices will all behave the same,
it's safer to configure them userland using udev rules.

This way is safer than hardcoding options per "recognized" model,
and possible regressions will be avoided in a first place.

Does the following still work?

Hi,

First apologies for delay.

Actually, I wished someone else will give you feedback earlier
since I don't have this screen anymore.

Anyway I know it worked well once applied to some 4.2 rc version.
(and also merged downstream in tizen on 3.14)

Doesn't the change look trivial ?
Do we assume it will work on later versions too ?

For the record here is the reference of the mentioned touchscreen :

MM500

I've contacted vendor, and It's not for sale anymore
(under this brand at least).
