Sabrelite boards can have an lvds screen attached with a built-in i2c touch
screen. Enable this in the dtsi.

The wakeup-gpio and the irq-line are sharing the same gpio line?

I guess i should have been more clear here; This is the touchscreen in
the hannstar display (already part of the dts) that was sold as an
accessoiry to the sabrelite.
Same as the screen that can be used on the boundary nitrogen6 boards
(which do have the touch part already enabled in the dts)

At least you should adapt the title to: "ARM: dts: imx6qdl-sabrelite: ..."
