Merge tag 'drm-misc-next-2016-11-29' of git://anongit.freedesktop.org/git/drm-misc into drm-next 

Big thing is that drm-misc is now officially a group maintainer/committer
model thing, with MAINTAINERS suitably updated. Otherwise just the usual
pile of misc things all over, nothing that stands out this time around.

* tag 'drm-misc-next-2016-11-29' of git://anongit.freedesktop.org/git/drm-misc: (33 commits)
  drm: Introduce drm_framebuffer_assign()
  drm/bridge: adv7511: Enable the audio data and clock pads on adv7533
  drm/bridge: adv7511: Add Audio support
  drm/edid: Consider alternate cea timings to be the same VIC
  drm/atomic: Constify drm_atomic_crtc_needs_modeset()
  drm: bridge: dw-hdmi: add ASoC dependency
  drm: Fix shift operations for drm_fb_helper::drm_target_preferred()
  drm: Avoid NULL dereference for DRM_LEGACY debug message
  drm: Use u64_to_user_ptr() helper for blob ioctls
  drm: Fix conflicting macro parameter in drm_mm_for_each_node_in_range()
  drm: Fixup kernel doc for driver->gem_create_object
  drm/hisilicon/hibmc: mark PM functions __maybe_unused
  drm/hisilicon/hibmc: Checking for NULL instead of IS_ERR()
  drm: bridge: add DesignWare HDMI I2S audio support
  drm: Check against color expansion in drm_mm_reserve_node()
  drm: Define drm_mm_for_each_node_in_range()
  drm/doc: Fix links in drm_property.c
  MAINTAINERS: Add link to drm-misc documentation
  vgaarb: use valid dev pointer in vgaarb_info()
  drm/atomic: Unconfuse the old_state mess in commmit_tail

* DOC: explicit fencing properties
*
* Explicit fencing allows userspace to control the buffer synchronization
* between devices. A Fence or a group of fences are transfered to/from
* userspace using Sync File fds and there are two DRM properties for that.
* IN_FENCE_FD on each DRM Plane to send fences to the kernel and
* OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
*
* As a contrast, with implicit fencing the kernel keeps track of any
* ongoing rendering, and automatically ensures that the atomic update waits
* for any pending rendering to complete. For shared buffers represented with
* a struct &dma_buf this is tracked in &reservation_object structures.
* Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
* whereas explicit fencing is what Android wants.
*
* "IN_FENCE_FD”:
* Use this property to pass a fence that DRM should wait on before
* proceeding with the Atomic Commit request and show the framebuffer for
* the plane on the screen. The fence can be either a normal fence or a
* merged one, the sync_file framework will handle both cases and use a
* fence_array if a merged fence is received. Passing -1 here means no
* fences to wait on.
*
* If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
* it will only check if the Sync File is a valid one.
*
* On the driver side the fence is stored on the @fence parameter of
* struct &drm_plane_state. Drivers which also support implicit fencing
* should set the implicit fence using drm_atomic_set_fence_for_plane(),
* to make sure there's consistent behaviour between drivers in precedence
* of implicit vs. explicit fencing.
*
* "OUT_FENCE_PTR”:
* Use this property to pass a file descriptor pointer to DRM. Once the
* Atomic Commit request call returns OUT_FENCE_PTR will be filled with
* the file descriptor number of a Sync File. This Sync File contains the
* CRTC fence that will be signaled when all framebuffers present on the
* Atomic Commit * request for that given CRTC are scanned out on the
* screen.
*
* The Atomic Commit request fails if a invalid pointer is passed. If the
* Atomic Commit request fails for any other reason the out fence fd
* returned will be -1. On a Atomic Commit with the
* DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
*
* Note that out-fences don't have a special interface to drivers and are
* internally represented by a struct &drm_pending_vblank_event in struct
* &drm_crtc_state, which is also used by the nonblocking atomic commit
* helpers and for the DRM event handling for existing userspace.

* DOC: standard connector properties
*
* DRM connectors have a few standardized properties:
*
* EDID:
* Blob property which contains the current EDID read from the sink. This
* is useful to parse sink identification information like vendor, model
* and serial. Drivers should update this property by calling
* drm_mode_connector_update_edid_property(), usually after having parsed
* the EDID using drm_add_edid_modes(). Userspace cannot change this
* property.
* DPMS:
* Legacy property for setting the power state of the connector. For atomic
* drivers this is only provided for backwards compatibility with existing
* drivers, it remaps to controlling the "ACTIVE" property on the CRTC the
* connector is linked to. Drivers should never set this property directly,
* it is handled by the DRM core by calling the ->dpms() callback in
* &drm_connector_funcs. Atomic drivers should implement this hook using
* drm_atomic_helper_connector_dpms(). This is the only property standard
* connector property that userspace can change.
* PATH:
* Connector path property to identify how this sink is physically
* connected. Used by DP MST. This should be set by calling
* drm_mode_connector_set_path_property(), in the case of DP MST with the
* path property the MST manager created. Userspace cannot change this
* property.
* TILE:
* Connector tile group property to indicate how a set of DRM connector
* compose together into one logical screen. This is used by both high-res
* external screens (often only using a single cable, but exposing multiple
* DP MST sinks), or high-res integrated panels (like dual-link DSI) which
* are not gen-locked. Note that for tiled panels which are genlocked, like
* dual-link LVDS or dual-link DSI, the driver should try to not expose the
* tiling and virtualize both &drm_crtc and &drm_plane if needed. Drivers
* should update this value using drm_mode_connector_set_tile_property().
* Userspace cannot change this property.
*
* Connectors also have one standardized atomic property:
*
* CRTC_ID:
* Mode object ID of the &drm_crtc this connector should be connected to.
