--- Comment #16 from Egbert Eich <eich at pdx.freedesktop.org> ---
Also, for HPD to work on the sink side the source must supply trickle power.
Would not be surprised if this doesn't get turned off by agressive runtime PM
as well - in which case the GPIO trick would not work either.
In this case when doing polling the relevant wells would have to be ungated
before the HPD status could be read.
