2009-12-16V4L/DVB (13612): IR: Move common IR code to drivers/media/IRMauro Carvalho Chehab
This is the first step of creating a common code for IR that can be used by other input devices. For now, keep IR dir at drivers/media, to easy the movement of the IR files, but later patches may move it to drivers/IR or drivers/input/IR. No functional changes is done on this patch.

2009-12-05V4L/DVB (13540): ir-common: Cleanup get key evdev codeMauro Carvalho Chehab
The same loop to seek for a key were used on different places. Also, no spinlock were protecting it to avoid the risk of replacing a keycode while seeking for a new code. This cleanup does: - create an unique function to seek for a code; - adds an spinlock to protect the table lookup; - remove some unused code; - simplifies to code to make it easier to understand. Basically no change in behavior should be noticed after this patch. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-12-05V4L/DVB (13532): ir-common: Add infrastructure to use a dynamic keycode tableMauro Carvalho Chehab
V4L drivers use an static keycode vector with 128 entries, where the scancode indexes the keycode. While this works, it limits the scancodes to have only 7 bits, not allowing for example full RC5 codes. Instead of implementing the same code on every V4L driver, provide a common infrastructure to handle the bigger tables, minimizing the changes inside each driver.
