2009-12-16V4L/DVB (13612): IR: Move common IR code to drivers/media/IRMauro Carvalho Chehab1-432/+0
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 (13542): ir-keytable: Allow dynamic table changeMauro Carvalho Chehab1-10/+197

2009-12-05V4L/DVB (13540): ir-common: Cleanup get key evdev codeMauro Carvalho Chehab1-62/+75
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 Chehab1-0/+156
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.
