drm/bridge: Add the necessary bits to support bus format negotiation
drm_bridge_state is extended to describe the input and output bus
configurations. These bus configurations are exposed through the
drm_bus_cfg struct which encodes the configuration of a physical
bus between two components in an output pipeline, usually between
two bridges, an encoder and a bridge, or a bridge and a connector.
The bus configuration is stored in drm_bridge_state separately for
the input and output buses, as seen from the point of view of each
bridge. The bus configuration of a bridge output is usually identical
to the configuration of the next bridge's input, but may differ if
the signals are modified between the two bridges, for instance by an
inverter on the board. The input and output configurations of a
bridge may differ if the bridge modifies the signals internally,
for instance by performing format conversion, or*modifying signals
polarities.
Bus format negotiation is automated by the core, drivers just have
to implement the ->atomic_get_{output,input}_bus_fmts() hooks if they
want to take part to this negotiation. Negotiation happens in reverse
order, starting from the last element of the chain (the one directly
connected to the display) up to the first element of the chain (the one
connected to the encoder).
During this negotiation all supported formats are tested until we find
one that works, meaning that the formats array should be in decreasing
preference order (assuming the driver has a preference order).
Note that the bus format negotiation works even if some elements in the
chain don't implement the ->atomic_get_{output,input}_bus_fmts() hooks.
In that case, the core advertises only MEDIA_BUS_FMT_FIXED and lets
the previous bridge element decide what to do (most of the time, bridge
drivers will pick a default bus format or extract this piece of
information from somewhere else, like a FW property).

drm: Initialize struct drm_crtc_state.no_vblank from device settings
At the end of a commit, atomic helpers can generate a fake VBLANK event
automatically. Originally implemented for writeback connectors, the
functionality can be used by any driver and/or hardware without proper
VBLANK interrupt.
The patch updates the documentation to make this behaviour official:
settings struct drm_crtc_state.no_vblank to true enables automatic
generation of fake VBLANK events.
The new interface drm_dev_has_vblank() returns true if vblanking has
been initialized for a device, or false otherwise. Atomic helpers use
this function when initializing no_vblank in the CRTC state in
drm_atomic_helper_check_modeset(). If vblanking has been initialized
for a device, no_blank is disabled. Otherwise it's enabled. Hence,
atomic helpers will automatically send out fake VBLANK events with any
driver that did not initialize vblanking.

* more precise documentation and commit message
v4:
* replace drm_crtc_has_vblank() with drm_dev_has_vblank()
* add drm_dev_has_vblank() in this patch

drm/auth: Drop master_create/destroy hooks
vmwgfx stopped using them.
With the drm device model that we've slowly evolved over the past few
years master status essentially controls access to display resources,
and nothing else. Since that's a pure access permission check drivers
should have no need at all to track additional state on a per file
basis.
Aside: For cleanup and restoring kernel-internal clients the grand
plan is to move everyone over to drm_client and
drm_master_internal_acquire/release, like the generic fbdev code
already does. That should get rid of most ->lastclose implementations,
and I think also subsumes any processing vmwgfx does in
master_set/drop.

drm/tidss: New driver for TI Keystone platform Display SubSystem
This patch adds a new DRM driver for Texas Instruments DSS IPs used on
Texas Instruments Keystone K2G, AM65x, and J721e SoCs. The new DSS IP is
a major change to the older DSS IP versions, which are supported by
the omapdrm driver. While on higher level the Keystone DSS resembles
the older DSS versions, the registers are completely different and the
internal pipelines differ a lot.
DSS IP found on K2G is an "ultra-light" version, and has only a single
plane and a single output. The K3 DSS IPs are found on AM65x and J721E
SoCs. AM65x DSS has two video ports, one full video plane, and another
"lite" plane without scaling support. J721E has 4 video ports, 2 video
planes and 2 lite planes. AM65x DSS has also an integrated OLDI (LVDS)
output.

drm/lima: support heap buffer creation
heap buffer is used as output of GP and input of PP for
Mali Utgard GPU. Size of heap buffer depends on the task
so is a runtime variable.
Previously we just create a large enough buffer as heap
buffer. Now we add a heap buffer type to be able to
increase the backup memory dynamically when GP fail due
to lack of heap memory.
