Add a driver for the OMAP2 camera block. OMAP2 is used in e.g. Nokia N800/N810 internet tablet. This driver uses the V4L2 internal ioctl interface. Signed-off-by:

This commit adds support for the CX24113 DVB-S tuner driver and thus support for the Technisat Skystar2 revision 2.8. The driver was created with the help of Technisat. Thank you very much. Signed-off-by:

Bogus controls currently include processing unit auto controls for which no corresponding manual control is available. Such auto controls make little sense if any, and are known to crash at least the SiGma Micro webcam. Signed-off-by:

The driver drops incomplete uncompressed video frames to avoid confusing userspace with corrupt data. Add a nodrop module parameter to turn that behaviour off and make all frames available to userspace. Signed-off-by:

A combined authorship patch from Hans Verkuil and Andy Walls. Raw VBI can now be captured but requires a video capture to be in progress as well. Signed-off-by:
-
Andy Walls authored
This is a port of the fixes Hans Verkuil made for ivtv/cx25840: The service_set field was used to determine whether raw or sliced VBI was desired. This is incorrect since it is perfectly valid to select sliced VBI with a service_set of 0. Instead the driver should check on VIDIOC_S_FMT whether the type field matches the raw or sliced VBI type. Updated the cx18 driver accordingly, including an additional check in cx18_start_v4l2_encode_stream() that didn't exist in ivtv. Signed-off-by:

cx18: Avoid making firmware API calls with the queue lock held. The source of MPEG strem corruption when not holding the queue lock was found to be that the MPEG buffer could be retrieved by the user app before it was sync'ed for the host cpu. Incoming buffers are now sync'ed before being put on q_full and releasing the queue lock. We can thus avoid the sometimes lengthy call to the firmware for CPU_DE_SET_MDL while holding the queue lock, so we can get better performance. Signed-off-by:

cx18: Add module parameters for finer control over buffer allocations. User now has the option of setting smaller buffers to get lower latency transfers from the encoder. User can also now set the number of buffers used for a stream explicitly. Signed-off-by:

Andy Walls authored
cx18: Allow more than 63 capture buffers in rotation per stream. Implement q_busy to hold buffers the firmware has for use. q_free holds truly unused buffers in a pool. New buffers are given to the firmware as soon as the firmware returns one, if there are any to give to the firmware. Signed-off-by:

Eliminate q_io from stream buffer handling in anticipation of upcoming changes in buffer handling. q_io was a holdover from ivtv and it's function in cx18 was trivial and not necessary. We just push things back onto the front of q_full now, instead of maintaining a 1 buffer q_io queue. Signed-off-by:

In the function cx88_audio_initdev, the value card has been created using snd_card_new. The other error handling code in this function frees the value using snd_card_free. I have thus changed the first error case to do the same. On the other hand, it may be that card is not sufficiently initialized at this point to use snd_card_free, in which case something else should be done to free the memory in the error case. In the function snd_cx88_create the call kfree(chip) in one error case looks suspicious, both because it is not done in the other error code, and because chip points into the middle of the memory allocated by snd_card_new, ie it is not itself associated with a separate kmalloc. Therefore I have removed it. The semantic match that finds the first problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S,S1; position p1,p2,p3; expression E,E1; type T,T1; expression *ptr != NULL; @@ ( if ((x@p1 = snd_card_new(...)) == NULL) S | x@p1 = snd_card_new(...); ) ... when != snd_card_free(...,(T)x,...) when != if (...) { <+... snd_card_free(...,(T)x,...) ...+> } when != true x == NULL || ... when != x = E when != E = (T)x when any ( if (x == NULL || ...)

Use the new format-negotiation infrastructure, support all four YUV422 packed and the planar formats. The new translation structure enables to build the format list with buswidth, depth, host format and camera format checked, so that it's not done anymore on try_fmt nor set_fmt. Signed-off-by:

Allocate and fill a list of formats, supported by this specific camera-host combination. Use it for format enumeration. Take care to stay backwards-compatible. Camera hosts rely on sensor formats available, as well as host specific translations. We add a structure so that hosts can define a translation table and use it for format check and setup.

We anyway don't follow the s_fmt_vid_cap / g_fmt_vid_cap / try_fmt_vid_cap naming, and soc-camera is so far only about video capture, let's simplify operation names a bit further. set_fmt_cap / try_fmt_cap wasn't a very good choice too. Signed-off-by:

Pixel format requested by the user is not necessarily the same, as what a sensor driver provides. There are situations, when a camera host driver provides the required format, but requires a different format from the sensor. Further, the list of formats, supported by sensors is pretty static and can be pretty good described with a constant list of structures. Whereas decisions, made by camera host drivers to support requested formats can be quite complex, therefore it is better to let the host driver do the work. Signed-off-by:

cx18: cx18_writel_expect() should not declare success on a PCI read error. This removes the potential for cx18_write*_expect() calls to not accomplish a PCI write successfully as expected. The CX18-AV core uses the *expect() calls often and this may be the source of intermittent audio problems and standands switching problems. Signed-off-by:

tda8290 were using some random video standard for FM. This results on random errors. Instead, program tda8290 in expert mode, using a configuration near the one specified on NXP datasheet for tda8295 (available on their site). Also, properly display that the device is on radio mode.

Probably due to a removed code, tda827x were doing some wrong calculus at the returned frequency. I suspect that the original idea were to return the programmed divisor converted into frequency again. However, the current code is sometimes multiplying the programmed frequency by 62500, and, on other cases, like radio, it dividing it by 1000. Instead of doing such math, let's just store the frequency value as requested by the caller module. Cc: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: -
