Enable the Hall effect sensor (flip cover) for OnePlus 6/6T.
The GPIO is mapped to SW_LID events as in msm8916, msm8994,
msm8998 devices.

One fun thing I discovered is that if suspend is broken for whatever
reason and you get a magnet close to a device with it mapped to SW_LID,
you'll essentially get a hang or a reboot lol
