--- Comment #19 from Jani Nikula <jani.nikula at intel.com> ---
Do you have CONFIG_PINCTRL_GEMINILAKE kernel config option enabled?

I do suspect there's something wrong with the GPIO code (either in the pincntrl
part or i915). Disabling the GPIO setting worked in bug 108826 but I believe
that then works by accident; apparently the panels in question don't absolutely
require the GPIOs to be changed from whatever the GOP did. And apparently
setting the GPIOs properly is required for D330. Again, just my educated
guesses.
