* [media] vivid: use V4L2_DV_FL_IS_CE_VIDEO instead of V4L2_DV_BT_STD_CEA861Hans Verkuil2015-04-08
| | | | | | | | Don't rely on V4L2_DV_BT_STD_CEA861 since that include the 640x480p format, which is an IT format, not CE. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: add support to set CVT, GTF timingsPrashant Laddha2015-04-08
| | | | | | | | | | | | In addition to v4l2_find_dv_timings_cap(), where timings are searched against the list of preset timings, the incoming timing from v4l2-ctl is checked against CVT and GTF standards. If it confirms to be CVT or GTF, it is treated as valid timing and vivid format is updated with new timings.

* [media] vivid: add CVT,GTF standards to vivid dv timings capsPrashant Laddha2015-04-08
| | | | | | | | | | | | | | | | | Currently vivid supports V4L2_DV_BT_STD_DMT and V4L2_DV_BT_STD_CEA861 discrete video standards. Extending the capability set to allow for setting CVT and GTF standards. This change, along with adding the support for calculating CVT, GTF timings in v4l2-ctl would extend the number of resolutions supported by vivid to almost any custom resolution. Also extending the limits on min and max pixel clock to accommodate pixel clock range provided by cvt/gtf for resolutions ranging from 640x360p50 to 4kx2Kp60.

* [media] vivid: report only one frameintervalHans Verkuil2015-04-02
| | | | | | | | | | | The vivid driver reports a range of frame intervals for non-webcams, when in fact the frame interval is fixed for those inputs as it depends on the DV timings or standard.

* [media] vivid-tpg: correctly average the two pixels in gen_twopix()Hans Verkuil2015-04-02
| | | | | | | | | | | gen_twopix() is always called twice: once for the first and once for the second pixel. Improve the code to properly average the two if the format requires horizontal downsampling. This is necessary for patterns like 1x1 red/blue checkers.

* [media] vivid-tpg: precalculate downsampled linesHans Verkuil2015-04-02
| | | | | | | | | | | | | | | | | When dealing with vertical downsampling two successive lines have to be averaged. In the case of the test pattern generator that only happens if the two lines are using different patterns. So precalculate the average between two pattern lines: one of pattern P and one of pattern P + 1. That way there is no need to do any on-the-fly downsampling: it's all done in the precalculate phase. This patch also implements horizontal downsampling in the precalculate phase. The only thing that needs to be done is to half the width since the actual downsampling happens when two pixels at a time are generated.

* [media] vivid-tpg: add hor/vert downsampling fieldsHans Verkuil2015-04-02
| | | | | | | | | | | | This is step one of supporting horizontal and vertical downsampling. This just adds support for the h/vdownsampling fields and it increases the maximum number of planes to 3. Currently none of the planar formats need horizontal or vertical downsampling, so this change has no effect at the moment.

* [media] vivid: fix test pattern movement for V4L2_FIELD_ALTERNATEHans Verkuil2015-04-02
| | | | | | | | | | | | | | The successive TOP/BOTTOM fields did not move as they should: only every other field actually changed position. The cause was that the tpg needs to know if it is dealing with a FIELD_ALTERNATE case since that requires slightly different handling.

* [media] vivid sdr: fix broken sine tone generated for sdr FMPrashant Laddha2015-03-02
| | | | | | | | | | | | | | | | FM (frequency modulated) signal for SDR is generated by varying the phase, where phase variation is proportional to input signal. It is seen that, the larger phase increments leads to discontinuities in the signal recovered after demodulation. Reducing the extent of phase variation with respect to input signal, equivalent to reducing the modulation index. Tested using FM receiver flow graph in gnuradio-companion.

* [media] vivid sdr: Use LUT based implementation for sin/cos()Prashant Laddha2015-03-02
| | | | | | | | | | | | | | | | | | | The common implementation for sin/cos in include/linux/fixp-arith.h has been improved recently to provide higher precision. Replacing native implementation of sin/cos in vivid sdr with common implementation. This serves two purposes: 1. Improved accuracy: the native implementation based on the Taylor series is more prone to rounding errors. 2. Reuse of common function: this is better compared to maintaining native versions for each driver.
