Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
Daniel writes:
As promised a stash of (mostly) fixes. Two pieces of non-fixes included:
- A notch more gtt refactoring from Ben, beating to death with igt in our
nightly testing.
- Support for display display-less server chips (again from Ben). New hw
support which is only likely to break itself ;-)
Otherwise just tons of fixes:
- hpd irq storm mitigation from Egbert Eich. Your -next tree already has
the infrastructure, this here just supplies the logic.
- sdvo hw state check fix from Egbert Eich
- fb cb tune settings for the pch pll clocks on cpt/ppt
- "Bring a bigger gun" coherence workaround for multi-threade, mulit-core
& thrashing tiled gtt cpu access from Chris.
- Update haswell mPHY code.
- l3$ caching for context objects on ivb/hsw (Chris).
- dp aux refclock fix for haswell (Jani)
- moar overclocking fixes for snb/ivb (Ben)
- ecobits ppgtt pte caching control fixes from Ville
- fence stride check fixes and limit improvements (Ville)
- fix up crtc force restoring, potentially resulting in tons of hw state
check WARNs
- OOPS fix for NULL derefencing of fb pointers when force-restoring a crtc
when other crtcs are disabled and the force-restored crtc is _not_ the
first one.
- Fix pfit disabling on gen2/3.
- Haswell ring freq scaling fixes (Chris).
- backlight init/teardown fix (failed eDP init killed the lvds backlight)
from Jani
- cpt/ppt fdi polarity fixes from Paulo (should help a lot of the FDI link
train failures).
- And a bunch of smaller things all over.
