[PATCH 0/4] Stylus-on-touchscreen device support

This patchset adds support for stylus-on-touchscreen devices as found on
the OneMix 3 Pro and Dell Inspiron 15 7000 2-in-1 (7591), among others;
with it, they properly behave like a drawing tablet.

Patches 2 and 4 funxionally depend on patch 1.
Patch 4 needs patch 3 to apply.

The output of this patchset and the need for a kernel, rather than
userspace, patch was previously discussed here:
