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
7 Please note: the maximum voltage for the CEC line is 3.63V, for the HPD and
12 - compatible: value must be "cec-gpio".
13 - cec-gpios: gpio that the CEC line is connected to. The line should be
16 If the CEC line is associated with an HDMI receiver/transmitter, then the
19 - hdmi-phandle - phandle to the HDMI controller, see also cec.txt.
21 If the CEC line is not associated with an HDMI receiver/transmitter, then
24 - hpd-gpios: gpio that the HPD line is connected to.
28 - v5-gpios: gpio that the 5V line is connected to.
