This patch makes in-kernel decoding with the stock Streamzap PC Remote work out of the box. There are quite a few things going on in this patch, all related to getting this working: 1) I had to enable reporting of a long space at the end of each signal, or I had weird buffering and keybounce issues. 2) The keymap has been reworked slightly to match actual decoded values, the first edition was missing the pre-data bits present in the lirc config file for this remote. 3) There's a whole new decoder included, specifically for the not-quite-RC5 15-bit protocol variant used by the Streamzap PC Remote. The decoder, while usable with other recievers (tested with an mceusb receiver), will only be loaded by the streamzap driver, as its likely not of use in almost all other situations. This can be revisited if/when all keytable loading (and disabling of unneeded protocol decoder engines) is moved to userspace, but for now, I think this makes the most sense. Note that I did try to enable handling the streamzap RC5-ish protocol in the current RC5 decoder, but there's no particularly easy way to tell if its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then, in testing an attempted decoder merge, only 2/3 of the keys were properly recognized as being the 15-bit variant and decoded correctly, the rest were close enough to compliant with 14-bit that they were decoded as such (but they have overlap with one another, and thus we can't just shrug and use the 14-bit decoded values). Also of note in this patch is the removal of the streamzap driver's internal delay buffer. Per discussion w/Christoph, it shouldn't be needed by lirc any longer anyway, and it doesn't seem to make any difference to the in-kernel decoder engine. That being the case, I'm yanking it all out, as it greatly simplifies the driver code. Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
