3 The HDMI CEC GPIO module supports CEC implementations where the CEC line
4 is hooked up to a pull-up GPIO line and - optionally - the HPD line is
5 hooked up to another GPIO line.
7 Please note: the maximum voltage for the CEC line is 3.63V, for the HPD and
9 when connecting them to a GPIO line.
12 - compatible: value must be "cec-gpio".
13 - cec-gpios: gpio that the CEC line is connected to. The line should be
19 - hdmi-phandle - phandle to the HDMI controller, see also cec.txt.
22 the following property is optional and can be used for debugging HPD changes:
