[Why]
The stream->mode_changed flag can persist in the following sequence
of atomic commits:
Commit 1:
Enable CRTC0 (mode_changed = true), Enable CRTC1 (mode_changed = true)
Commit 2:
Disable CRTC1 (mode_changed = false)
In this sequence we want to keep the exiting CRTC0 but it's not in the
atomic state for the commit since it hasn't been modified. In this case
the stream->mode_changed flag persists as true and we don't re-program
the planes for the existing stream.
[How]
The flag needs to be cleared and it makes the most sense to do it within
DC after the state has been committed. Nothing following dc_commit_state
should think that the stream's mode has changed.

[Why]
Cursor updates used to happen after vblank/flip/stream updates before
the stream update refactor. They now happen before stream updates
which means that they're not going to be synced with fb changes
and that they're going to programmed for pipes that we're disabling
within the same commit.
[How]
Move them after stream updates.

[Why]
Whenever a stream or plane is added or removed from the context the
pointer will change from old to new. We set lock and validation
needed in these cases. But not all of these cases match update_type
from dm_determine_update_type_for_commit - an example being overlay
plane updates.
There are warnings for a few of these cases that should be fixed.
[How]
We can closer align to DC (and lock_and_validation_needed) by
comparing stream and plane pointers.
Since the old stream/old plane state is never freed until sometime
after the commit tail work finishes we are guaranteed to never get
back the same block of memory when we remove and create a stream or
plane state in the same commit.

[Why]
If a commit updates an overlay plane via the legacy plane IOCTL
then the only plane in the state will be the overlay plane.
Overlay planes need to be added first to the DC context, but in the
scenario above the plane will be added last. This will result in wrong
z-order during rendering.
[How]
If any non-cursor plane has been updated then the rest of the
non-cursor planes should be added to the CRTC state.
The cursor plane doesn't need to be included for stream updates and
locking it will cause performance issues. It should be ignored.
DC requires that the surface count passed during stream updates
be the number of surfaces currently on the stream to enable fast
updates. This previously wasn't the case without this patch, so this
also allows this optimization to occur.

[Why]
Previously, a change removed code that would send a pipe set command
to dmcu each time the backlight was set, as it was thought to be
superfluous. However, it is possible for the backlight to be set
before a valid pipe has been set, which causes DMCU to hang after a
DPMS restore on some systems.
[How]
Send a pipe set command to DMCU prior to setting the backlight.

[Why]
Certain tests fail after a fresh reboot. This is caused by writing to
registers prior to ungating the stream we're trying to program.
[How]
Make sure the stream is ungated before writing to its registers.
This also enables power-gating plane resources before init_hw
initializes them.
Additionally, this does some refactoring to move gating/ungating
from enable/disable_plane functions to where stream resources are
enabled/disabled.

across suspend and resume cycles by default. This can probably
be loosened for Hybrid Graphics (_PR3) laptops where I think the

On HP ProBook 4540s, if PM-runtime is enabled in the radeon driver
and the direct-complete optimization is used for the radeon device
during system-wide suspend, the system doesn't resume.
Preventing direct-complete from being used with the radeon device by
setting the DPM_FLAG_NEVER_SKIP driver flag for it makes the problem
go away, which indicates that direct-complete is not safe for the
radeon driver in general and should not be used with it (at least
for now).
This fixes a regression introduced by commit c62ec4610c40
("PM / core: Fix direct_complete handling for devices with no
callbacks") which allowed direct-complete to be applied to
devices without PM callbacks (again) which in turn unlocked
direct-complete for radeon on HP ProBook 4540s.

This patch attaches the colorspace connector property to the
hdmi connector. Based on colorspace change, modeset will be
triggered to switch to new colorspace.
Based on colorspace property value create an infoframe
with appropriate colorspace. This can be used to send an
infoframe packet with proper colorspace value set which
will help to enable wider color gamut like BT2020 on sink.
This patch attaches and enables HDMI colorspace, DP will be
taken care separately.
v2: Merged the changes of creating infoframe as well to this
patch as per Maarten's suggestion.
v3: Addressed review comments from Shashank. Separated HDMI
and DP colorspaces as suggested by Ville and Maarten.
v4: Addressed Chris and Ville's review comments, and created a
common colorspace property for DP and HDMI, filtered the list
based on the colorspaces supported by the respective protocol
standard. Handle the default case properly.
v5: Merged the DP handling along with platform colorspace
handling as per Shashank's comments.
v6: Reverted to old design of exposing all colorspaces to
userspace as per Ville's review comment
v7: Fixed a checkpatch complaint, Addressed Maarten' review
comment, updated the RB from Maarten and Jani's ack.
v8: Moved colorspace AVI Infoframe programming to drm core and
removed from driver as per Ville's suggestion.
v9: Added a check to only allow RGB colorpsaces to be set in
infoframe though the colorspace property. Since there is no output
csc property to control planar formats and it will be added later.
Changes for RGB->YUV conversion inside driver without userspace
knowledge is still supported. This is as per Ville's suggestion.
v10: Fixed an error in if check.
v11: Dropped the check for planar vs RGB and allow all the colorspaces.
Onus will be on userspace to pick whatever pipe output it is able to
drive.
v12: Added Ville's RB.

v6: Added bit wise macro for various fields of colorimetry for easier
understanding and review as per Ville's comments. Moved the same out of

Create a new connector property to program colorspace to sink
devices. Modern sink devices support more than 1 type of
colorspace like 601, 709, BT2020 etc. This helps to switch
based on content type which is to be displayed. The decision
lies with compositors as to in which scenarios, a particular
colorspace will be picked.
This will be helpful mostly to switch to higher gamut colorspaces
like BT2020 when the media content is encoded as BT2020. Thereby
giving a good visual experience to users.
The expectation from userspace is that it should parse the EDID
and get supported colorspaces. Use this property and switch to the
one supported. Sink supported colorspaces should be retrieved by
userspace from EDID and driver will not explicitly expose them.
Basically the expectation from userspace is:
- Set up CRTC DEGAMMA/CTM/GAMMA to convert to some sink
colorspace
- Set this new property to let the sink know what it
converted the CRTC output to.
v2: Addressed Maarten and Ville's review comments. Enhanced
the colorspace enum to incorporate both HDMI and DP supported
colorspaces. Also, added a default option for colorspace.
v3: Removed Adobe references from enum definitions as per
Ville, Hans Verkuil and Jonas Karlman suggestions. Changed
Default to an unset state where driver will assign the colorspace
is not chosen by user, suggested by Ville and Maarten. Addressed
other misc review comments from Maarten. Split the changes to
have separate colorspace property for DP and HDMI.
v4: Addressed Chris and Ville's review comments, and created a
common colorspace property for DP and HDMI, filtered the list
based on the colorspaces supported by the respective protocol
standard.
v5: Made the property creation helper accept enum list based on
platform capabilties as suggested by Shashank. Consolidated HDMI
and DP property creation in the common helper.
v6: Addressed Shashank's review comments.
v7: Added defines instead of enum in uapi as per Brian Starkey's
suggestion in order to go with string matching at userspace. Updated
the commit message to add more details as well kernel docs.
v8: Addressed Maarten's review comments.
v9: Removed macro defines from uapi as per Brian Starkey and Daniel
Stone's comments and moved to drm include file. Moved back to older
design with exposing all HDMI colorspaces to userspace since infoframe
capability is there even on legacy platforms, as per Ville's review
comments.
v10: Fixed sparse warnings, updated the RB from Maarten and Jani's ack.
v11: Addressed Ville's review comments. Updated the Macro naming and
added DCI-P3 colorspace as well, defined in CTA 861.G spec.
v12: Appended BT709 and SMPTE 170M with YCC information as per Ville's
review comment to be clear and not to be confused with RGB.
v13: Reorder the colorspace macros.
v14: Removed DP as of now, will be added later once full support is
enabled, as per Ville's suggestion. Added Ville's RB.

Convert string compares of DT node names to use of_node_name_eq helper

For instances using of_node_cmp, this has the side effect of now using

Now that the base struct drm_gem_object has a reservation_object, use it
and remove the private BO one.
We can't use the drm_gem_reservation_object_wait() helper for MSM
because (in theory) msm_gem_cpu_prep() will also do some cache
maintenance on the GEM object.

Many users of drm_gem_object embed a struct reservation_object into
their subclassed struct, so let's add one to struct drm_gem_object.
This will allow removing the reservation object from the subclasses
and removing the ->gem_prime_res_obj callback.
With the addition, add a drm_gem_reservation_object_wait() helper
function for drivers to use in wait ioctls.

It turns out that the hblk calculation actually follows a similar pattern
than the other packets. Rework a bit the calculation and add a comment.

The Allwinner BSP makes sure that we don't end up with a null start delay
or with a delay larger than vtotal.
The former condition is likely to happen now with the reworked start delay,
so make sure we enforce the same boundaries.

The current calculation for the video start delay in the current DSI driver
is that it is the total vertical size, minus the front porch and sync length,
plus 1. This equals to the active vertical size plus the back porch plus 1.
That 1 is coming in the Allwinner BSP from an variable that is set to 1.
However, if we look at the Allwinner BSP more closely, and especially in
the "legacy" code for the display (in drivers/video/sunxi/legacy/), we can
see that this variable is actually computed from the porches and the sync
minus 10, clamped between 8 and 100.
This fixes the start delay symptom we've seen on some panels (vblank
timeouts with vertical white stripes at the bottom of the panel).

The current code allows the TCON clock divider to have a range between 4
and 127 when feeding the DSI controller.
The only display supported so far had a display clock rate that ended up
using a divider of 4, but testing with other displays show that only 4
seems to be functional.
This also aligns with what Allwinner is doing in their BSP, so let's just
hardcode that we want a divider of 4 when using the DSI output.
