I've never seen anything declaring the units in the kernel myself. I guess
whoever was adding this feature was having some units in mind as well as
some user space application as a target consumer. Maybe we should look in
the logs and/or ask on linux-input.

I should note that the HID report descriptor format has unit exponent item
which could be applied to keep precision while using appropriate unit size
(meters, millimeters, or whatever), but the base units (without the
exponent) are as I described.
