Add a new framework to handle controls which makes life for driver developers much easier. Note that this patch moves some of the control support that used to be in v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl struct anymore, which makes it more general. The remainder of v4l2-ctrls.c is all new. Highlights include: - No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL, S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers or subdevs. New wrapper functions are provided that can just be plugged in. Once everything has been converted these wrapper functions can be removed as well. - When subdevices are added their controls can be automatically merged with the bridge driver's controls. - Most drivers just need to implement s_ctrl to set the controls. The framework handles the locking and tries to be as 'atomic' as possible. - Ready for the subdev device nodes: the same mechanism applies to subdevs and their device nodes as well. Sub-device drivers can make controls local, preventing them from being merged with bridge drivers. - Takes care of backwards compatibility handling of VIDIOC_S_CTRL and VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent. CTRL_CLASS controls are automatically added. Signed-off-by:

Added this info to Kconfig and mt9m111.c, some comment cleanup, replaced 'mt9m11x'-statements by clarifications or driver name. Driver is fully compatible to mt9m131 which has only additional functions compared to mt9m111. Those aren't used anyway at the moment. Signed-off-by:

The emma uses bufnum 1 and 0. This patch tells the bufqueue to change the next buffer to the next one and not the current one. Otherwise the BUG_ON above will trigger everytime. Signed-off-by:

The exchanges for sensor mt9v111 are different with bridges zc301 and zc303. The exchanges for the bridge zc303 were those of the bad named tas5130ck. These mt9v111 exchanges have been adjusted from the ms-Windows public files vm30x.inf (for 0ac8:301b) and usbvm303.inf (for 0ac8:303b). Signed-off-by:

Some webcams as ov511 may find many times an end of image. In this case, with the last patch in image concatenation (commit 799b1bd41f398054d46fd35f73abd01c4009f6ca), the image pointer was NULL and the system crashed in memcpy(). Signed-off-by:

Corrupted video frames are dropped by default by the driver for uncompressed formats. Data corruption is not less problematic for compressed formats, so frame drop should be enabled by default for those formats as well. Mark buffers as faulty when an isochronous packet loss is detected for any format, or when the buffer length doesn't match the image size for uncompressed formats. Drop erroneous buffers regardless of whether the format is compressed or uncompressed. Signed-off-by:

This patch adds a defintion for the "Print" button found on HP OEM versions of the MCE remote. All of the other keys found on the HP OEM version of the remote match the other keys as already defined. Because, who doesn't need "remote printing", while one is sitting on the couch across from one's PC? ;) Signed-off-by:

Some ir input devices have small buffer, and interrupt the host each time it is full (or half full) Add a helper that automaticly handles timeouts, and also automaticly merges samples of same time (space-space) Such samples might be placed by hardware because size of sample in the buffer is small (a byte for example). Also remove constness from ir_dev_props, because it now contains timeout settings that driver might want to change Signed-off-by:

Repeat space is 4 units, not 8. Current code would never trigger a repeat. However that isn't true for NECX, so repeat there must be handled differently. Signed-off-by:

It is perfectly possible to have ir_raw_event_work running concurently on two cpus, thus we must protect it from that situation. This stems from the fact that if hardware sends short packets of samples we might end up queueing the work item more times that nessesary. Such job isn't well suited for a workqueue, so use a kernel thread. Signed-off-by:

This ports lirc_streamzap.c over to ir-core in-place, to be followed by a patch moving the driver over to drivers/media/IR/streamzap.c and enabling the proper Kconfig bits. Presently, the in-kernel keymap doesn't work, as the stock Streamzap remote uses an RC-5-like, but not-quite-RC-5 protocol, which the in-kernel RC-5 decoder doesn't cope with. The remote can be used right now with the lirc bridge driver though, and other remotes (at least an RC-6(A) MCE remote) work perfectly with the driver. I'll take a look at making the existing RC-5 decoder cope with this odd duck, possibly implement another standalone decoder engine, or just throw up my hands and say "meh, use lirc"... But the driver itself should be perfectly sound. Remaining items on the streamzap TODO list: - add LIRC_SET_REC_TIMEOUT-alike support - add LIRC_GET_M{AX,IN}_TIMEOUT-alike support - add LIRC_GET_REC_RESOLUTION-alike support All of the above should be trivial to add. There are patches pending to add this support to ir-core from Maxim Levitsky, and I'll take care of these once his patches get integrated. None of them are currently essential though.

The ir_input_dev gets filled in by __ir_input_register, the one allocated in imon_init_idev was being overwritten by the correct one shortly after it was initialized (ultimately resulting in a memory leak). Additionally, there was an ill-advised memcpy into that extraneous ir_input_dev which gets fixed by this. Ill-advised memcpy pointed out by Dmitry Torokhov, bad usage of ir_input_dev pointed out by Maxim Levitsky. Signed-off-by:
