there are a few bits and pieces, but no single spec. https://www.kernel.org/doc/Documentation/input/input.txt (see section 5) https://www.kernel.org/doc/Documentation/input/event-codes.txt how the protocol A and B work: https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt more internal stuff: https://www.kernel.org/doc/Documentation/input/input-programming.txt but aside from that it's largely a look at linux/input.h and figure it out from there... seen from userspace it's a relatively simple protocol, though slightly quirky in places (which prompted libevdev).
