Here are some fixes for drm/rockchip, these fixes base on drm-next.

These fixes works on my popmetal(rk3288) board.

About patch: drm/atomic-helper: Export framebuffer_changed()
Daniel Vetter ack for merging it through rockchip git trees, so framebuffer_changed() can be reused by drm/rockchip.

All others looks good, so I'd like you can land them.

This pull request just includes the !CONFIG_PM_SLEEP build fix for
vc4.

  drm/vc4: Remove broken attempt at GPU reset using genpd.

A bunch of etnaviv fixes for 4.5-rc. Most of them are fixing
things in code paths that will only be hit if something goes
wrong, which have been unearthed by more extensive testing.

The only thing that doesn't really qualify as fixes is an UAPI
extension that userspace wants to rely on being present, so
I want to fast-track this into 4.5 before etnaviv ends up in a
released kernel.

* 'drm-etnaviv-fixes' of git://git.pengutronix.de/git/lst/linux:
  drm/etnaviv: call correct function when trying to vmap a DMABUF
  drm/etnaviv: rename etnaviv_gem_vaddr to etnaviv_gem_vmap
  drm/etnaviv: fix get pages error path in etnaviv_gem_vaddr
  drm/etnaviv: fix memory leak in IOMMU init path
  drm/etnaviv: add further minor features and varyings count

Misc radeon and amdgpu fixes:
- SMU firmware loading fix for Stoney
- DP audio fixes for DCE4.1
- Don't expose fbdev device if no connectors
- fix page table LRU list update handling

* 'drm-fixes-4.5' of git://people.freedesktop.org/~agd5f/linux:
  drm/amdgpu: only move pt bos in LRU list on success
  drm/radeon: fix DP audio support for APU with DCE4.1 display engine
  drm/radeon: Add a common function for DFS handling
  drm/radeon: cleaned up VCO output settings for DP audio
  drm/amd/powerplay: Update SMU firmware loading for Stoney
  drm/amdgpu: don't init fbdev if we don't have any connectors
  drm/radeon: only init fbdev if we have connectors
  drm/radeon: Ensure radeon bo is unreserved in radeon_gem_va_ioctl
  drm/amdgpu: fix next_rptr handling for debugfs
  drm/radeon: properly byte swap vce firmware setup
  drm/amdgpu: add a message to indicate when powerplay is enabled (v2)
  drm/amdgpu: fix amdgpu_bo_pin_restricted VRAM placing v2
  drm/amd/amdgpu: Improve amdgpu_dpm* macros to avoid unexpected result (v2)
  drm/amdgpu: Allow the driver to load if amdgpu.powerplay=1 on asics without powerplay support
  drm/amdgpu: Use drm_calloc_large for VM page_tables array
  drm/amdgpu: Add some tweaks to gfx 8 soft reset
  drm/amdgpu: fix tonga smu resume

This fixes a race condition in the error case: since the pt bos have not
necessarily been reserved in case of an error, we could move a pt bo that
is currently in the middle of being evicted/moved by another process,
which then resulted in a BUG_ON in ttm_bo_add_to_lru.
