[meta-freescale] [meta-fsl-arm] QT5 on SabreLite

Maybe try different device (e.g. /dev/input/event0). AFAIR it should be
like this for example:

... -plugin tslib:/dev/input/event0

or instead of adding this as command line argument it can be set as
environment variable:

export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0

Best regards,
