Geert Uytterhoeven d519432c85 drm: rcar-du: Remove obsolete rcar-du-r8a779x platform_device_id entries
Since commit a483dcbfa2 ("ARM: shmobile: lager: Remove legacy
board support"), R-Car Gen2 SoCs are only supported in generic DT-only
ARM multi-platform builds.  The driver doesn't need to match platform
devices by name anymore, hence remove the corresponding
platform_device_id entry.

Dave Airlie 9ace42b1d1 Merge branch 'drm-dwhdmi-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next
This series:
* adds support for interlaced video modes to the ipu-v3 driver
  and dw_hdmi bridge.
* reworks the dw_hdmi connector enable/disable support, to ensure that
  when DRM disables the output, it stays disabled irrespective of the
  hotplug state.
* adds support for connector forcing, so we can force the hotplug state
  for this connector.
* adds the ALSA AHB audio driver to the bridge: Iwai has acked the
  audio driver.
* a few fixes to the ACR calculations to allow more modes to work with
  audio on iMX6.

Fabio has independently tested this series, so all patches here carry
his tested-by tag.

  drm: bridge/dw_hdmi: replace CTS calculation for the ACR
  drm: bridge/dw_hdmi: remove ratio support from ACR code

I have another backmerge here since things became messy and I didn't
realize you resolved some of them already (usually you complain when
there's a conflict ...).

For 4.4 I plan one more feature round after this and then that's it.

Alex Deucher 29275a9b09 drm/amdgpu/dce10: Use cursor_set2 hook for enabling / disabling the HW cursor
The cursor_set2 hook provides the cursor hotspot position within the
cursor image. When the hotspot position changes, we can adjust the cursor
position such that the hotspot doesn't move on the screen. This prevents
the cursor from appearing to intermittently jump around on the screen
when the position of the hotspot within the cursor image changes.

Alex Deucher c2fe16aa36 drm/amdgpu/atom: add support for new div32 opcodes (v3)
Better precision than the regular div opcode.

v2: drop 64 bit divide
v3: fix op handling.  This actually is a 64 bit divide.

Ilia Mirkin 25d295882a drm/nouveau/bios: fix OF loading
Currently OF bios load fails for a few reasons:
 - checksum failure
 - bios size too small
 - no PCIR header
 - bios length not a multiple of 4

In this change, we resolve all of the above by ignoring any checksum
failures (since OF VBIOS tends not to have a checksum), and faking the
PCIR data when loading from OF.

Ben Skeggs f231976c2e drm/nouveau/fbcon: take runpm reference when userspace has an open fd
We need to do this in order to prevent accesses to the device while it's
powered down.  Userspace may have an mmap of the fb, and there's no good
way (that I know of) to prevent it from touching the device otherwise.

This fixes some nasty races between runpm and plymouth on some systems,
which result in the GPU getting very upset and hanging the boot.

Ondrej Zary 953132b56a drm/nouveau/nouveau: Disable AGP for SiS 761
SiS 761 chipset does not support AGP cards but has AGP capability (for
the onboard video). At least PC Chips A31G board using this chipset has
an AGP-like AGPro slot that's wired to the PCI bus. Enabling AGP will
fail (GPU lockup and software fbcon, X11 hangs).

Add support for matching just the host bridge in nvkm_device_agp_quirks
and add entry for SiS 761 with mode 0 (AGP disabled).
