| 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. |
