Merge tag 'drm-dp-quirk-for-v4.12-rc4' of git://people.freedesktop.org/~airlied/linux
Pull drm displayport quirk support:
"DP quirk for usb c dongles.
As mentioned I have a separate request for fixing a regression, but
also keeping the broken hw working, for certain USB-C DP adapters they
require a minimised n/m parameters, but an attempt to do this
generically has failed, we need to quirk these specific adapters.
However doing it generically regressed some eDP panels.
This pull adds the infrastructure and a quirk for the adapter"
