[PATCH v3 0/9] media: vivid: add HDMI (dis)connect emulation

[Johan Korsnes <johan.korsnes@gmail.com>]

This patch series makes vivid V4L2-compliant by adding HDMI (dis)-
connect emulation. This is done by by adding a custom display_present
control to vivid output HDMI devices, along with the following standard
controls:

-ctrl_tx_edid_present
-ctrl_tx_hotplug
-ctrl_tx_rxsense
-ctrl_rx_power_present

With regard to v4l2-compliance:
Series fixes the following 1/1 warning for HDMI input devices:
   -V4L2_CID_DV_RX_POWER_PRESENT not found for input n
Series fixes the following 2/2 warnings for HDMI ouptut devices:
   -V4L2_CID_DV_TX_HOTPLUG not found for output n
   -V4L2_CID_DV_TX_EDID_PRESENT not found for output n

Regards,
Johan

  not sure those really apply. Please let me know if they do, and I
