Merge tag 'drm-fixes-for-v4.7-rc8-intel-kbl' of git://people.freedesktop.org/~airlied/linux
Pull intel kabylake drm fixes from Dave Airlie: "As mentioned Intel has gathered all the Kabylake fixes from -next, which we've enabled in 4.7 for the first time, these are pretty much limited in scope to only affects kabylake, which is hw that isn't shipping yet. So I'm mostly okay with it going in now. If we don't land this, it might be a good idea to disable kabylake support in 4.7 before we ship" * tag 'drm-fixes-for-v4.7-rc8-intel-kbl' of git://people.freedesktop.org/~airlied/linux: (28 commits) drm/i915/kbl: Introduce the first official DMC for Kabylake. drm/i915: Introduce Kabypoint PCH for Kabylake H/DT. drm/i915/gen9: implement WaConextSwitchWithConcurrentTLBInvalidate drm/i915/gen9: Add WaFbcHighMemBwCorruptionAvoidance drm/i195/fbc: Add WaFbcNukeOnHostModify drm/i915/gen9: Add WaFbcWakeMemOn drm/i915/gen9: Add WaFbcTurnOffFbcWatermark drm/i915/kbl: Add WaClearSlmSpaceAtContextSwitch drm/i915/gen9: Add WaEnableChickenDCPR drm/i915/kbl: Add WaDisableSbeCacheDispatchPortSharing drm/i915/kbl: Add WaDisableGafsUnitClkGating drm/i915/kbl: Add WaForGAMHang drm/i915: Add WaInsertDummyPushConstP for bxt and kbl drm/i915/kbl: Add WaDisableDynamicCreditSharing drm/i915/kbl: Add WaDisableGamClockGating drm/i915/gen9: Enable must set chicken bits in config0 reg drm/i915/kbl: Add WaDisableLSQCROPERFforOCL drm/i915/kbl: Add WaDisableSDEUnitClockGating drm/i915/kbl: Add WaDisableFenceDestinationToSLM for A0 drm/i915/kbl: Add WaEnableGapsTsvCreditFix ...
