Merge branch 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
drm-intel-next-2014-01-10: - final bits for runtime D3 on Haswell from Paul (now enabled fully) - parse the backlight modulation freq information in the VBT from Jani (but not yet used) - more watermark improvements from Ville for ilk-ivb and bdw - bugfixes for fastboot from Jesse - watermark fix for i830M (but not yet everything) - vlv vga hotplug w/a (Imre) - piles of other small improvements, cleanups and fixes all over Note that the pull request includes a backmerge of the last drm-fixes pulled into Linus' tree - things where getting a bit too messy. So the shortlog also contains a bunch of patches from Linus tree. Please yell if you want me to frob it for you a bit. * 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel: (609 commits) drm/i915/bdw: make sure south port interrupts are enabled properly v2 drm/i915: Include more information in disabled hotplug interrupt warning drm/i915: Only complain about a rogue hotplug IRQ after disabling drm/i915: Only WARN about a stuck hotplug irq ONCE drm/i915: s/hotplugt_status_gen4/hotplug_status_g4x/
