2008-10-12V4L/DVB (8690): tuner-3036: remove driverHans Verkuil
This driver is for VERY old i2c-over-parallel port teletext receiver boxes. Rather then spending effort on converting this driver to V4L2, and since it is extremely unlikely that anyone still uses one of these devices, it was decided to drop it (after discussing this as well with the original author, Phil Blundell).

Old driver for the dpc7146 demonstration board that is no longer relevant. The last time this was tested on actual hardware was probably around 2002. Since this is a driver for a demonstration board the decision was made (after discussing this with the original author, Michael Hunold) to remove it rather than spending a lot of effort continually updating this driver to stay in sync with the latest internal V4L2 or I2C API.

2008-10-12V4L/DVB (8625): saa7134: Add NEC prococol IR decoding capabilityMauro Carvalho Chehab
This patch adds the capability of decoding NEC protocol, received via GPIO18 line. This GPIO port can trigger saa7134 IRQ. A future improvement would be to make it a little more generic to work also with GPIO16 line. A pure IRQ code didn't work, since some delays were introduced on the tests we did. A possible approach would be to use polling at a rate of 2.5 ms or less. If a new code were taken, a code similar to nec_task() could be used. However, this would add an extra overhead to kernel, and will consume more power. Due to that, we took an hybrid approach: an IRQ upper half to trigger when a new key is received and a bottom half to convert pulse-distance into a keycode. The bottom half is polling based, to improve performance. During the bottom half proccess, GPIO18 IRQ line is disabled, preventing IRQ reentrancy and improving performance a little bit.
