Hi Stefan,
Suspend of VC4 HDMI will likely triggers a warning from
vc4_hdmi_connector_detect_ctx() during poll of connector status.
The power management will prevent the resume and keep the relevant
power domain disabled.
Since there is no reason to poll the connector status during
suspend, the polling should be disabled during this.
What about HDMI-CEC? I don't know well enough how CEC integrates at
this level but CEC can wake up the device over HDMI from a TV display
for example so if this affects that, while it's maybe not required for
first pass, I know the rpi is used in a lot of media use cases so the
ability to wake up via CEC would certainly be welcomed.
unfortunately i don't know much about HDMI-CEC, too. The only thing I
noticed was that I currently cannot configure vc4 as a wakeup source.
