+ <body>
+ <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>
