* [media] use v4l2_get_timestamp where possibleArnd Bergmann2015-10-017-24/+9
| | | | | | | | | | | | | | | | | 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.

* [media] exynos4-is: use monotonic timestamps as advertizedArnd Bergmann2015-10-011-7/+1
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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.

| | | | | | | | | | | | | - poll doesn't return negative values, so you can't return -EINVAL.

* [media] vivid: use Bradford method when converting Rec. 709 to NTSC 1953Hans Verkuil2015-10-011-43/+47
| | | | | | | | | | | | | | | | | 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.

* [media] v4l2-compat-ioctl32: replace pr_warn by pr_debugHans Verkuil2015-09-251-2/+2
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | rcar_vin_set_fmt() defaults to PAL when the subdevice's querystd() method call fails (e.g. due to I2C error). This doesn't work very well when a camera being used outputs NTSC which has different order of fields and resolution. Let us stop pretending and return the actual error except when the querystd() method is not implemented, in which case we'll have to set the 'field' variable to V4L2_FIELD_NONE. Note that doing this would prevent video capture on at least Renesas Henninger/ Porter boards where I2C seems particularly buggy.
