Hi all, the WMI interfaces in some Lenovo Ideapad laptops provide notification callbacks when the laptop orientation changes, reporting 4 different values defining the new orientation. I'd like to extend the ideapad-laptop driver with this information; but how should it be reported to userspace? I initially thought of the input subsystem, but I cannot find any suitable event codes; then I would probably export it as a device under /sys, or are there better options? Are there other devices which provide coarse orientation data to userspace, which I might want to use as a reference? I guess that at least some display screens have this feature.
