+      <p>There are two working proof-of-concept drivers for the
+	AM335x touchscreen and for the official Raspberry Pi's touchscreen
+	LCD.</p>
+	
+      <p>Proper touchscreen support would consist of a userland event
+	reading API, a kernel event reporting API, and kernel hardware
+	drivers for specific devices.  There is an ongoing effort to port
+	the Linux evdev API to &os; so applications that use libraries like
+	libinput or tslib could be used without any major changes.  Since
+	it is not yet complete, I created a naive evdev-like API for both
+	kernel and tslib and was able to run a demo on a Beaglebone Black
+	with 4DCAPE-43T.</p>
+
+      <p>Once evdev makes it into the tree, both hardware drivers
+	can be modified to include "report events"
+	portions and committed.</p>
