When ttm_tt_swapout() fails, the current code calls
ttm_resource_add_bulk_move() followed by ttm_resource_move_to_lru_tail()
to restore the resource's bulk_move membership.
However, ttm_resource_move_to_lru_tail() places the resource at the tail
of the LRU list which, relative to the walk cursor's hitch node (placed
immediately after the resource when it was yielded), puts the resource
*in front of the* the hitch. The next list_for_each_entry_continue() from
the hitch finds the same resource again, causing an infinite loop.
Fix by deferring del_bulk_move to the success path only.
On the success path, TTM_TT_FLAG_SWAPPED has just been set by
ttm_tt_swapout() but the resource is still tracked in the bulk_move range,
so ttm_resource_del_bulk_move()'s !ttm_resource_unevictable() guard would
incorrectly skip the removal. Introduce
ttm_resource_del_bulk_move_unevictable() which bypasses that guard.

The second Late Binding version allows to send payload bigger
than client MTU by splitting it to chunks and uses separate
firmware client for transfer.
The component interface is unchanged and driver doing all splitting.
Only one Late Binding version is supported by firmware.
When Late binding version 2 is supported, the new client is advertised
by firmware and existing MKHI will have version 2.
This helps driver to select the right mode of work.

Deprecate simple-encoder and simple-display-pipe helpers in favor of
regular atomic helpers. Remove the related documentation. Add TODO
item for converting the remaining drivers.
These helpers have been deprecated for years and many drivers have
been updated to not use them. Still there are a few left and we
occasionally receive new drivers build upon them. Marking them as
deprecated will hopefully resolve these problems. The TODO items
should be easy enough for getting new voluteers started on DRM driver
development.

Use drm_atomic_helper_commit_tail_rpm() as commit tail to update the
plane after enabling the CRTC. Then remove the plane-update code from
mipi_dbi_enable_flush() and inline the remaining backlight code where
necessary.
Mipi-dbi's current commit tail drm_atomic_helper_commit_tail() first
updates the plane and then enables the CRTC. But the CRTC enablement
includes power management that prevents the initial plane update from
working. Hence, each mipi-dbi driver includes a plane update in their
CRTC enablement; in the form of mipi_dbi_enable_flush() or custom code.
Using drm_atomic_helper_commit_tail_rpm() enables the CRTC before any
plane updates. Hence the additional plane update can be removed from
mipi_dbi_enable_flush() and a number of drivers.
This leaves backlight_enable() in the helper, which can now be inlined
into affected drivers. Drivers now enable the CRTC plus an optional
backlight and then automatically update the plane.
In the case of disabling the display, drm_atomic_helper_commit_tail_rpm()
only disables the CRTC without touching the plane at all. Mipi-dbi's
mipi_dbi_pipe_disable() already contains the necessary logic.
Removing the plane update from the CRTC enablement will also help with
converting mipi-dbi from simple-pipe helpers to regular atomic helpers.

The hdmi_colorspace enum was defined to represent the colorspace value
of the HDMI infoframes. It was later used by some HDMI drivers to
express the output format they should be setting up.
During the introduction of the HDMI helpers, it then was used to
represent it in the drm_connector_hdmi_state structure.
However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_*
defines, and now with the drm_output_color_format enum. Let's
consolidate around drm_output_color_format in drm_connector_hdmi_state

The EDID parsing code initially introduced the DRM_COLOR_FORMAT_*
defines to represent the sink capabilities. Since a given sink could
support multiple formats, it was first defined as a bitmask.
However, the core and drivers have since leveraged those defines to
represent both the supported formats but also the current format being
used.
Considering the latter case, the more natural, and consistent, thing to
do would be to create an enum of all the possible formats, and then list
the supported formats using a bitmask of the individual enum values.
Let's create a new enum following that pattern, drm_output_color_format,
while maintaining the DRM_COLOR_FORMAT_* compatibility to make the
transition easier.

Drivers having a struct drm_bridge pointer pointing to a bridge in many
cases hold that reference until the owning device is removed. In those
cases the reference to the bridge can be put in the .remove callback
(possibly using devm actions) or in the .destroy func (possibly with the
help of struct drm_bridge::next_bridge). At those moments the driver should
not be operating anymore and won't dereference the bridge pointer after it
is put.
However there are cases when drivers need to stop holding a reference to a
bridge even when their device is not being removed. This is the case for
bridge hot-unplug, when a bridge is removed but the previous entity (bridge
or encoder) is staying. In such case the "previous entity" needs to put it
but cannot do it via devm or .destroy, because it is not being removed.
The easy way to dispose of such pointer is:
drm_bridge_put(my_priv->some_bridge);
my_priv->some_bridge = NULL;
However this is risky because there is a time window between the two lines
where the reference is put, and thus the bridge could be deallocated, but
the pointer is still assigned. If other functions of the same driver were
invoked concurrently they might dereference my_priv->some_bridge during
that window, resulting in use-after-free.
A correct solution is to clear the pointer before putting the reference,
but that needs a temporary variable:
struct drm_bridge *temp = my_priv->some_bridge;
my_priv->some_bridge = NULL;
drm_bridge_put(temp);
This solution is however annoying to write, so the incorrect version might
still sneak in.
Add a simple, easy to use function to put a bridge after setting its
pointer to NULL in the correct way.

Some display controllers can be hardware programmed to show non-black
colors for pixels that are either not covered by any plane or are
exposed through transparent regions of higher planes. This feature can
help reduce memory bandwidth usage, e.g. in compositors managing a UI
with a solid background color while using smaller planes to render the
remaining content.
To support this capability, introduce the BACKGROUND_COLOR standard DRM
mode property, which can be attached to a CRTC through the
drm_crtc_attach_background_color_property() helper function.
Additionally, define a 64-bit ARGB format value to be built with the
help of a couple of dedicated DRM_ARGB64_PREP*() helpers. Individual
color components can be extracted with desired precision using the
corresponding DRM_ARGB64_GET*() macros.

Introduces the DRM RAS infrastructure over generic netlink.
The new interface allows drivers to expose RAS nodes and their
associated error counters to userspace in a structured and extensible
way. Each drm_ras node can register its own set of error counters, which
are then discoverable and queryable through netlink operations. This
lays the groundwork for reporting and managing hardware error states
in a unified manner across different DRM drivers.
Currently it only supports error-counter nodes. But it can be
extended later.
The registration is also not tied to any drm node, so it can be
used by accel devices as well.
It uses the new and mandatory YAML description format stored in
Documentation/netlink/specs/. This forces a single generic netlink
family namespace for the entire drm: "drm-ras".
But multiple-endpoints are supported within the single family.
Any modification to this API needs to be applied to
Documentation/netlink/specs/drm_ras.yaml before regenerating the
code:
$ tools/net/ynl/pyynl/ynl_gen_c.py --spec \
Documentation/netlink/specs/drm_ras.yaml --mode uapi --header \
