Hi,

This series aims at fixing a complete and silent hang when one tries to use CEC while the display output is off.

This can be tested with:

echo off > /sys/class/drm/card0-HDMI-A-1/status cec-ctl --tuner -p 1.0.0.0 cec-compliance

This series addresses it by making sure the HDMI controller is powered up as soon as the CEC device is opened by the userspace.

Applied, thanks! Maxime
