Merge tag 'drm-intel-next-2013-05-20-merged' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
Daniel writes: Highlights (copy-pasted from my testing cycle mails): - fbc support for Haswell (Rodrigo) - streamlined workaround comments, including an igt tool to grep for them (Damien) - sdvo and TV out cleanups, including a fixup for sdvo multifunction devices - refactor our eDP mess a bit (Imre) - don't register the hdmi connector on haswell when desktop eDP is present - vlv support is no longer preliminary! - more vlv fixes from Jesse for stolen and dpll handling - more flexible power well checking infrastructure from Paulo - a few gtt patches from Ben - a bit of OCD cleanups for transcoder #defines and an assorted pile of smaller things. - fixes for the gmch modeset sequence - a bit of OCD around plane/pipe usage (Ville) - vlv turbo support (Jesse) - tons of vlv modeset fixes (Jesse et al.) - vlv pte write fixes (Kenneth Graunke) - hpd filtering to avoid costly probes on unaffected outputs (Egbert Eich) - intel dev_info cleanups and refactorings (Damien) - vlv rc6 support (Jesse) - random pile of fixes around non-24bpp modes handling - asle/opregion cleanups and locking fixes (Jani) - dp dpll refactoring - improvements for reduced_clock computation on g4x/ilk+ - pfit state refactored to use pipe_config (Jesse) - lots more computed modeset state moved to pipe_config, including readout and cross-check support - fdi auto-dithering for ivb B/C links, using the neat pipe_config improvements - drm_rect helpers plus sprite clipping fixes (Ville) - hw context refcounting (Mika + Ben) * tag 'drm-intel-next-2013-05-20-merged' of git://people.freedesktop.org/~danvet/drm-intel: (155 commits) drm/i915: add support for dvo Chrontel 7010B drm/i915: Use pipe config state to control gmch pfit enable/disable drm/i915: Use pipe_config state to disable ilk+ pfit drm/i915: panel fitter hw state readout&check support drm/i915: implement WADPOClockGatingDisable for LPT drm/i915: Add missing platform tags to FBC workaround comments drm/i915: rip out an unused lvds_reg variable drm/i915: Compute WR PLL dividers dynamically drm/i915: HSW FBC WaFbcDisableDpfcClockGating drm/i915: HSW FBC WaFbcAsynchFlipDisableFbcQueue drm/i915: Enable FBC at Haswell. drm/i915: IVB FBC WaFbcDisableDpfcClockGating drm/i915: IVB FBC WaFbcAsynchFlipDisableFbcQueue drm/i915: Add support for FBC on Ivybridge. drm/i915: Organize VBT stuff inside drm_i915_private drm/i915: make SDVO TV-out work for multifunction devices drm/i915: rip out now unused is_foo tracking from crtc code drm/i915: rip out TV-out lore ... drm/i915: drop TVclock special casing on ilk+ drm/i915: move sdvo TV clock computation to intel_sdvo.c ...
