Common bindings for HDMI CEC adapters

  • hdmi-phandle: phandle to the HDMI controller.

  • needs-hpd: if present the CEC support is only available when the HPD
    is high. Some boards only let the CEC pin through if the HPD is high,
    for example if there is a level converter that uses the HPD to power
    up or down.
