There are two working proof-of-concept drivers for the + AM335x touchscreen and for the official Raspberry Pi's touchscreen + LCD.

+ +

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.

+ +

Once evdev makes it into the tree, both hardware drivers + can be modified to include "report events" + portions and committed.
