Amlogic Meson SoCs include a infrared remote control receiver that can operate in two modes: "NEC" mode in which the hardware decodes frames using the NEC IR protocol, and "general" mode in which the receiver simply reports the duration of pulses and spaces for software decoding. This is a driver for the IR receiver that implements software decoding of received frames.

There are several arch-specific media drivers that don't require asm-specific includes and can be successfully compiled on x86. Add COMPILE_TEST dependency for them, in order to allow a broader test on those drivers. That helps static analysis tools like Coverity to discover eventual troubles there.

Now that the protocol is part of the scancode, it is pretty easy to merge the rc5 and streamzap decoders. An additional advantage is that the decoder is now stricter as it waits for the trailing silence before determining that a command is a valid rc5/streamzap command (which avoids collisions that I've seen with e.g. Sony protocols).

Add ImgTec IR decoder driver to the build system. Signed-off-by: James Hogan <james.hogan@imgtec.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
Add a raw decoder for the Sharp protocol. It uses a pulse distance modulation with a pulse of 320us and a bit period of 2ms for a logical 1 and 1ms for a logical 0. The first part of the message consists of a 5-bit address, an 8-bit command, and two other bits, followed by a 40ms gap before the echo message which is an inverted version of the main message except for the address bits.

This patch adds support to ST RC driver, which is basically a IR/UHF receiver and transmitter. This IP (IRB) is common across all the ST parts for settop box platforms. IRB is embedded in ST COMMS IP block. It supports both Rx & Tx functionality. This driver adds only Rx functionality via LIRC codec.
