Email clients info for Linux
======================================================================
+Git
+----------------------------------------------------------------------
+These days most developers use `git send-email` instead of regular
+email clients. The man page for this is quite good. On the receiving
+end, maintainers use `git am` to apply the patches.
+
+If you are new to git then send your first patch to yourself. Save it
+as raw text including all the headers. Run `git am raw_email.txt` and
+then review the changelog with `git log`. When that works then send
+the patch to the appropriate mailing list(s).

+The NTC (Negative Temperature Coefficient) thermistor is a simple thermistor

The NTC driver provides lookup tables with a linear approximation function
and four circuit models with an option not to use any of the four models.

+INPUT_PROP_TOPBUTTONPAD:
+-----------------------
+Some laptops, most notably the Lenovo *40 series provide a trackstick
+device but do not have physical buttons associated with the trackstick
+device. Instead, the top area of the touchpad is marked to show
+visual/haptic areas for left, middle, right buttons intended to be used

+If INPUT_PROP_TOPBUTTONPAD is set, userspace should emulate buttons
