With X11 ( before wayland ) I can set up my touchscreen with:

     xinput --list

find my device: "Advanced Silicon S.A. CoolTouch(TM) System"

and can simply set the props I need with:

     xinput set-prop 'Advanced Silicon S.A. CoolTouch(TM) System'
--type=float 'Coordinate Transformation Matrix' 0.533333333333333, 0,
0.466666666666667, 0, 1, 0, 0, 0, 1

But now, `xinput list` did not show my any real devices, only some mystery
generic ones as this:

      ⎡ Virtual core pointer                     id=2    [master pointer
(3)]
      ⎜   ↳ Virtual core XTEST pointer               id=4    [slave pointer
(2)]
      ⎜   ↳ xwayland-pointer:14                      id=6    [slave pointer
(2)]
      ⎜   ↳ xwayland-relative-pointer:14             id=7    [slave pointer
(2)]
      ⎜   ↳ xwayland-touch:14                        id=9    [slave pointer
(2)]
      ⎣ Virtual core keyboard                    id=3    [master keyboard
(2)]
          ↳ Virtual core XTEST keyboard              id=5    [slave keyboard
(3)]
          ↳ xwayland-keyboard:14                     id=8    [slave keyboard
(3)]

So I only see some mystery wayland pseudo devices.

https://who-t.blogspot.com.au/2017/05/xinput-list-shows-xwayland-pointer.html

With `libinput-list-devices` I can see my touch device, but I can not find
any documentation how I can configure devices for libinput. All docs tell my
that it can be done with `xinput` with is not true for wayland on fedora.
Any idea?

Q: How can I configure input devices on wayland in fedora 25.

well, there's the LIBINPUT_CALIBRATION_MATRIX but it's not actually what you
need here since you have multiscreen mapping issue.
https://wayland.freedesktop.org/libinput/doc/latest/udev_config.html

mutter should map the touchscreen to a single screen, does it not do that?

This might be:
