Uploaded kernel module for kernel version 4.4.48+, which corresponds to 2017-02-16-raspbian.

Kernel module is now for Raspbian 2016-11-25

Module now gets divisors and translation table from device tree overlay. This means that you won't have to recompile the module for non-Model M keyboards.

Updated files and changed instructions accordingly.

Compiled module is now for raspbian-2016-3-18.

Fixed the RXD pin symbol: it was pointing the wrong direction, as pointed out by a sharp reader.

I clarified the description of how the circuit works. There seems to have been some confusion - I simply use the UART to read the keyboard bitstream, which happens to be standard serial in most cases. No fancy polling code was necessary.

Also added schematic file.
