            Bug ID: 105153
           Summary: Raspberry official Touchscreen absolute axes issue
                    libinput 1.10
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: jacopo.vichi at gmail.com

Step to reproduce:
1) Install ArchlinuxARM on RaspberryPi 3 (installing official RPI Touchscreen
7inch)
2) startx
=> Cannot touch on the top area

Found that kernel resolve it as 800x600 (not 800x480).
Followed the guide and with "touchpad-edge-detector 800x480 /dev/input/event0"
added this on /etc/udev/hwdb.d/61-evdev-local.hwdb
evdev:name:*
 EVDEV_ABS_00=2:800:1
 EVDEV_ABS_01=2:480:1
 EVDEV_ABS_35=2:800:1
 EVDEV_ABS_36=2:480:1

It was working without udev patch in previous version..
Unfortunately touchpad-edge-detector cannot give me an identifier string so I
override all the evdev device (the only one connected is this touchscreen)
