and 'adap->phys_addr' will fail.

055075a3e8 [media] vivid: fix g_edid implementation
The VIDIOC_G_EDID implementation in vivid didn't take edid->start_block into account when
copying the EDID data.

Make sure that the internal EDID is updated with the correct CEC physical address. Currently
the returned EDID is updated, but that will only work well if edid->start_block is 0.

6f8adea2b6 [media] vivid: add CEC emulation
The vivid driver has been extended to provide CEC adapters for the HDMI
input and HDMI outputs in order to test CEC applications.

This CEC emulation is faithful to the CEC timings (i.e., it all at a
snail's pace).

29103668e9 [media] vivid: add CVT,GTF standards to vivid dv timings caps
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.
