This code implements the transmitter which is currently implemented in the staging lirc_zilog driver. The new code does not need a signal database, iow. the haup-ir-blaster.bin firmware file is no longer needed, and the driver does not know anything about the keycodes in that file. Instead, the new driver can send raw IR, but the hardware is limited to few different lengths of pulse and spaces, so it is best to use generated IR rather than recorded IR.
