- Add missing V4L2_CTRL_TYPE_U32 documentation - Remove 'which are actually different on the hardware' sentence which is confusing. I think the idea was to let the user know that the step can be different for different hardware, but that's obvious because otherwise you wouldn't need to specify the step value. - Clarify that V4L2_CTRL_COMPOUND_TYPES also applies to arrays.

Array controls weren't skipped when only V4L2_CTRL_FLAG_NEXT_CTRL was provided (so no V4L2_CTRL_FLAG_NEXT_COMPOUND was set). This is wrong since arrays are also considered compound controls (i.e. with more than one value), and applications that do not know about arrays will not be able to handle such controls. Fix the test to include arrays. Signed-off-by:

This is a preparation for a change to the type of v4l2 timestamps. v4l2_get_timestamp() is a helper function that reads the monotonic time and stores it into a 'struct timeval'. Multiple drivers implement the same thing themselves for historic reasons. Changing them all to use v4l2_get_timestamp() is more consistent and reduces the amount of code duplication, and most importantly simplifies the following changes. Signed-off-by:

The exynos4 fimc capture driver claims to use monotonic timestamps but calls ktime_get_real_ts(). This is both an incorrect API use, and a bad idea because of the y2038 problem and the fact that the wall clock time is not reliable for timestamps across suspend or settimeofday(). This changes the driver to use the normal v4l2_get_timestamp() function like all other drivers. Signed-off-by:

The vbi port should pass any tuner/input/standard information on to the video port since in the input and tuner are shared between the two. There is no reason to duplicate this code, just pass the ioctls on to the video encoder port. Signed-off-by:

Hans Verkuil authored
- the frequency range was never set - there was no initial frequency - missing index/tuner checks - inconsistent standard reporting - removed unnecessary tuner type checks (the core handles that) - clamp frequency to the valid frequency range as per the V4L2 spec Signed-off-by:

Fix various v4l2-compliance issues in the formatting ioctls: - the vbi device implemented video format ioctls which make no senses for a vbi device, remove them. - remove the unused ts_packet_size and ts_packet_count fields. - fill in colorspace and field. - fill in sizeimage with a default value. - for the video node the get, set and try format functions all do the same thing, so combine into a single function.

Now that saa7164 uses v4l2_fh and that poll() has been fixed, it is trivial to add support for control events. Signed-off-by:
-
Hans Verkuil authored
- poll doesn't return negative values, so you can't return -EINVAL. Instead return POLLERR. - poll can't be called if !video_is_registered(), so this test can be dropped. - poll can never do a blocking wait, so remove that check. - poll shouldn't attempt to start streaming if the caller isn't interested in read events.

The V4L2_COLORSPACE_470_SYSTEM_M (aka NTSC 1953) colorspace has a different whitepoint (C) compared to Rec. 709 (D65). The Bradford method is the recommended method to compensate for that when converting a Rec. 709 color to an NTSC 1953 color. See http://www.brucelindbloom.com/index.html?Eqn_ChromAdapt.html for more details on the Bradford method. This patch updates the Rec. 709 to NTSC 1953 matrix so that it includes the chromatic adaptation as calculated by the Bradford method, and it recalculates the tpg_csc_colors table accordingly.

Every time compat32 encounters an unknown ioctl it will call pr_warn. However, that's very irritating since it is perfectly normal that this happens. For example, applications often try to call an ioctl to see if it exists, and if that's used with an older kernel where compat32 doesn't support that ioctl yet, then it starts spamming the kernel log. So replace pr_warn by pr_debug. Signed-off-by:

After adding the format check in try_fmt()/set_fmt(), we don't need any format check in configure_geometry(). So make configure_geometry() as void type. Signed-off-by:
-
Josh Wu authored
As in set_fmt() function we only need to know which format is been set, we don't need to access the ISI hardware in this moment. So move the configure_geometry(), which access the ISI hardware, to start_streaming() will make code more consistent and simpler. Signed-off-by:

Josh Wu authored
In the function configure_geometry(), we will setup the ISI CFG2 according to the sensor output format. It make no sense to just read back the CFG2 register and just set part of it. So just set up this register directly makes things simpler. Currently only support YUV format from camera sensor. Signed-off-by:
