Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is the main drm pull, it has a shared branch with some alsa crossover but everything should be acked by relevant people. New drivers: - ATMEL HLCDC driver - designware HDMI core support (used in multiple SoCs). core: - lots more atomic modesetting work, properties and atomic ioctl (hidden under option) - bridge rework allows support for Samsung exynos chromebooks to work finally. - some more panels supported i915: - atomic plane update support - DSI uses shared DSI infrastructure - Skylake basic support is all merged now - component framework used for i915/snd-hda interactions - write-combine cpu memory mappings - engine init code refactored - full ppgtt enabled where execlists are enabled. - cherryview rps/gpu turbo and pipe CRC support. radeon: - indirect draw support for evergreen/cayman - SMC and manual fan control for SI/CI - Displayport audio support amdkfd: - SDMA usermode queue support - replace suballocator usage with more suitable one - rework for allowing interfacing to more than radeon nouveau: - major renaming in prep for later splitting work - merge arm platform driver into nouveau - GK20A reclocking support msm: - conversion to atomic modesetting - YUV support for mdp4/5 - eDP support - hw cursor for mdp5 tegra: - conversion to atomic modesetting - better suspend/resume support for child devices rcar-du: - interlaced support imx: - move to using dw_hdmi shared support - mode_fixup support sti: - DVO support - HDMI infoframe support exynos: - refactoring and cleanup, removed lots of internal unnecessary abstraction - exynos7 DECON display controller support Along with the usual bunch of fixes, cleanups etc" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (724 commits) drm/radeon: fix voltage setup on hawaii drm/radeon/dp: Set EDP_CONFIGURATION_SET for bridge chips if necessary drm/radeon: only enable kv/kb dpm interrupts once v3 drm/radeon: workaround for CP HW bug on CIK drm/radeon: Don't try to enable write-combining without PAT drm/radeon: use 0-255 rather than 0-100 for pwm fan range drm/i915: Clamp efficient frequency to valid range drm/i915: Really ignore long HPD pulses on eDP drm/exynos: Add DECON driver drm/i915: Correct the base value while updating LP_OUTPUT_HOLD in MIPI_PORT_CTRL drm/i915: Insert a command barrier on BLT/BSD cache flushes drm/i915: Drop vblank wait from intel_dp_link_down drm/exynos: fix NULL pointer reference drm/exynos: remove exynos_plane_dpms drm/exynos: remove mode property of exynos crtc drm/exynos: Remove exynos_plane_dpms() call with no effect drm/i915: Squelch overzealous uncore reset WARN_ON drm/i915: Take runtime pm reference on hangcheck_info drm/i915: Correct the IOSF Dev_FN field for IOSF transfers drm/exynos: fix DMA_ATTR_NO_KERNEL_MAPPING usage ...
