+description: |
+ The HDMI CEC GPIO module supports CEC implementations where the CEC line is
+ hooked up to a pull-up GPIO line and - optionally - the HPD line is hooked up
+ to another GPIO line.
+
+ Please note:: the maximum voltage for the CEC line is 3.63V, for the HPD and
+ 5V lines it is 5.3V. So you may need some sort of level conversion
+ circuitry when connecting them to a GPIO line.
