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.
