7 title: HDMI CEC GPIO
10 - Hans Verkuil <hverkuil-cisco@xs4all.nl>
13 The HDMI CEC GPIO module supports CEC implementations where the CEC line is
14 hooked up to a pull-up GPIO line and - optionally - the HPD line is hooked up
15 to another GPIO line.
17 Please note:: the maximum voltage for the CEC line is 3.63V, for the HPD and
