Especially when IR needs to do polling, it generates lots of wakeups per second. This makes no sense, if the input event device is closed. Adds a callback handler to the IR hardware driver, to allow registering an open/close ops. Signed-off-by:Mauro Carvalho Chehab <mchehab@redhat.com>

IR is an alias for Infrared Remote, while RC is an alias for Remote Controller. While currently all implementations are with Infrared Remote Controller, this subsystem is not meant to be used only by IR type of RC's. So, as discussed on both linux-media and linux-input, the better is to rename the subsystem as Remote Controller. While, currently, the only application that uses the /sys/class/irrcv is ir-keytable application, and its sysfs support works only with the current linux-next code, it is still possible to change the userspace API without the risk of breaking applications. So, better to rename this sooner than later. Later patches will be needed to rename the files and to move them away from drivers/media, but this is not a critical issue. So, for now, let's just change the name of the sysfs class/nodes. Signed-off-by: -

With the help of raw_register/raw_unregister, adds a sysfs group associated with the decoder, inside the corresponding irrcv node. Writing 1 to nec_decoder/enabled enables the decoder, while writing 0 disables it. Signed-off-by: -

Some decoders and a lirc_dev interface may need some other operations to work. For example: IR device register/unregister and ir_keydown events may need to be tracked. As some operations can occur in interrupt time, and a lock is needed to prevent un-registering a decode while decoding a key, the lock needed to be convert into a spin lock. Signed-off-by: -

Instead of hardcoding the protocols into ir-core, add a register interface for the IR protocol decoders, and convert ir-nec-decoder into a client of ir-core. With this approach, it is possible to dynamically load the needed IR protocols, and to add a RAW IR interface module, registered as one IR raw protocol decoder. This patch opens a way to register a lirc_dev interface to work as an userspace IR protocol decoder. Signed-off-by: -

At raw_decode mode, the key is processed after the end of a timer. The previous code resets the timer every time something is received at the IR port. While this works fine with IR's that don't implement repeat, like Avermedia RM-JX IR, it keeps waiting until keydown, on IR's that implement NEC repeat command, like the Terratec yellow. The solution is to change the behaviour to do the timeout after the first received data. The timeout is currently set to 15 ms, as it works fine with NEC protcocol. It may need some adjustments to support other protocols and to better handle spurious detections that may happen with some IR sensors. Signed-off-by: -

Adds a method to pass IR raw pulse/code events into ir-core. This is needed in order to support LIRC. It also helps to move common code from the drivers into the core. In order to allow testing, it implements a simple NEC protocol decoder at ir-nec-decoder.c file. The logic is about the same used at saa7134 driver that handles Avermedia M135A and Encore FM53 boards. Signed-off-by: -

The V4L2 specification requires drivers to use the write events in the file operations poll handler for output devices. The uvcvideo driver erroneously used read events for all devices. Fix this. Signed-off-by:

For the sequence streamon -> streamoff and again s_input, it fails to lock the signal, since streamoff puts TVP514x into power off state which leads to failure in sub-sequent s_input. So add powerup sequence in s_routing (if disabled), since it is important to lock the signal at this stage. Signed-off-by:
