Merge branch 'drm-next-3.12' of git://people.freedesktop.org/~agd5f/linux into drm-next
Alex writes: This is the radeon drm-next request. Big changes include: - support for dpm on CIK parts - support for ASPM on CIK parts - support for berlin GPUs - major ring handling cleanup - remove the old 3D blit code for bo moves in favor of CP DMA or sDMA - lots of bug fixes [airlied: fix up a bunch of conflicts from drm_order removal] * 'drm-next-3.12' of git://people.freedesktop.org/~agd5f/linux: (898 commits) drm/radeon/dpm: make sure dc performance level limits are valid (CI) drm/radeon/dpm: make sure dc performance level limits are valid (BTC-SI) (v2) drm/radeon: gcc fixes for extended dpm tables drm/radeon: gcc fixes for kb/kv dpm drm/radeon: gcc fixes for ci dpm drm/radeon: gcc fixes for si dpm drm/radeon: gcc fixes for ni dpm drm/radeon: gcc fixes for trinity dpm drm/radeon: gcc fixes for sumo dpm drm/radeonn: gcc fixes for rv7xx/eg/btc dpm drm/radeon: gcc fixes for rv6xx dpm drm/radeon: gcc fixes for radeon_atombios.c drm/radeon: enable UVD interrupts on CIK drm/radeon: fix init ordering for r600+ drm/radeon/dpm: only need to reprogram uvd if uvd pg is enabled drm/radeon: check the return value of uvd_v1_0_start in uvd_v1_0_init drm/radeon: split out radeon_uvd_resume from uvd_v4_2_resume radeon kms: fix uninitialised hotplug work usage in r100_irq_process() drm/radeon/audio: set up the sads on DCE3.2 asics drm/radeon: fix handling of variable sized arrays for router objects ...
