Virtual wide planes give high amount of flexibility, but it is not
always enough:
In parallel multirect case only the half of the usual width is supported
for tiled formats. Thus the whole width of two tiled multirect
rectangles can not be greater than max_linewidth, which is not enough
for some platforms/compositors.
Another example is as simple as wide YUV plane. YUV planes can not use
multirect, so currently they are limited to max_linewidth too.
Now that the planes are fully virtualized, add support for allocating
two SSPP blocks to drive a single DRM plane. This fixes both mentioned
cases and allows all planes to go up to 2*max_linewidth (at the cost of
making some of the planes unavailable to the user).

Only several SSPP blocks support such features as YUV output or scaling,
thus different DRM planes have different features. Properly utilizing
all planes requires the attention of the compositor, who should
prefer simpler planes to YUV-supporting ones. Otherwise it is very easy
to end up in a situation when all featureful planes are already
allocated for simple windows, leaving no spare plane for YUV playback.
To solve this problem make all planes virtual. Each plane is registered
as if it supports all possible features, but then at the runtime during
the atomic_check phase the driver selects backing SSPP block for each
plane.
As the planes are attached to the CRTC and not the encoder, the SSPP
blocks are also allocated per CRTC ID (all other resources are currently
allocated per encoder ID). This also matches the hardware requirement,
where both rectangles of a single SSPP can only be used with the LM
pair.
Note, this does not provide support for using two different SSPP blocks
for a single plane or using two rectangles of an SSPP to drive two
planes. Each plane still gets its own SSPP and can utilize either a solo
rectangle or both multirect rectangles depending on the resolution.
Note #2: By default support for virtual planes is turned off and the
driver still uses old code path with preallocated SSPP block for each
plane. To enable virtual planes, pass 'msm.dpu_use_virtual_planes=1'
kernel parameter.

On chipsets such as QCS615, there is no 3dmux present. In such
a case, a layer exceeding the max_mixer_width cannot be split,
hence cannot be supported.
Filter out the modes which exceed the max_mixer_width when there
is no 3dmux present. Also, add a check in the dpu_crtc_atomic_check()
to return failure for such modes.

During suspend/resume process all connectors are explicitly disabled and
then reenabled. However resume fails because of the connector_status check:
[dpu error]connector not connected 3
[drm:drm_mode_config_helper_resume [drm_kms_helper]] *ERROR* Failed to resume (-22)
It doesn't make sense to check for the Writeback connected status (and
other drivers don't perform such check), so drop the check.
It wasn't a problem before the commit 71174f362d67 ("drm/msm/dpu: move
writeback's atomic_check to dpu_writeback.c"), since encoder's
atomic_check() is called under a different conditions that the
connector's atomic_check() (e.g. it is not called if there is no
connected CRTC or if the corresponding connector is not a part of the
new state).

The IRQ indexes for the intf_6 underrun/vsync interrupts are swapped.
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 16) is the actual underrun interrupt and
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 17) is the vsync interrupt.
This causes timeout errors when using the DP2 controller, e.g.
[dpu error]enc37 frame done timeout
*ERROR* irq timeout id=37, intf_mode=INTF_MODE_VIDEO intf=6 wb=-1, pp=2, intr=0
*ERROR* wait disable failed: id:37 intf:6 ret:-110

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

There may be a potential integer overflow issue in

mode->vtotal, mode->hdisplay, and drm_mode_vrefresh(mode) are defined as
a smaller data type. The result of the calculation will be limited to
"int" in this case without correct casting. In screen with high
resolution and high refresh rate, integer overflow may happen.
So, we recommend adding an extra cast to prevent potential
integer overflow.

Add support for MSM8996, which - fun fact - was the SoC that this driver
(or rather SDE, its downstream origin) was meant for and first tested on.
It has some hardware that differs from the modern SoCs, so not a lot of
current structs could have been reused. It's also seemingly the only SoC
supported by DPU that uses RGB pipes.
Note, by default this platform is still handled by the MDP5 driver
unless the `msm.prefer_mdp5=false' parameter is provided.

Don't set the merge_3d pending flush bits if the mode_3d is
BLEND_3D_NONE.
Always flushing merge_3d can cause timeout issues when there are
multiple commits with concurrent writeback enabled.
This is because the video phys enc waits for the hw_ctl flush register
to be completely cleared [1] in its wait_for_commit_done(), but the WB
encoder always sets the merge_3d pending flush during each commit
regardless of if the merge_3d is actually active.
This means that the hw_ctl flush register will never be 0 when there are
multiple CWB commits and the video phys enc will hit vblank timeout
errors after the first CWB commit.

Historically CRTC resources (LMs and CTLs) were assigned in
dpu_crtc_atomic_begin(). The commit 9222cdd27e82 ("drm/msm/dpu: move hw
resource tracking to crtc state") simply moved resources to
struct dpu_crtc_state, without changing the code sequence. Later on the
commit b107603b4ad0 ("drm/msm/dpu: map mixer/ctl hw blocks in encoder
modeset") rearanged the code, but still kept the cstate->num_mixers
assignment to happen during commit phase. This makes dpu_crtc_state
inconsistent between consequent atomic_check() calls.
Move CRTC resource assignment to happen at the end of
dpu_encoder_virt_atomic_check().

The commit b954fa6baaca ("drm/msm/dpu: Refactor rm iterator") removed
zero-init of the hw_ctl array, but didn't change the error condition,
that checked for hw_ctl[i] being NULL. At the same time because of the
early returns in case of an error dpu_encoder_phys might be left with
the resources assigned in the previous state. Rework assigning of hw_pp
/ hw_ctl to the dpu_encoder_phys in order to make sure they are always
set correctly.

Pull non-MM updates from Andrew Morton:
"Many singleton patches - please see the various changelogs for
details.
Quite a lot of nilfs2 work this time around.
Notable patch series in this pull request are:
- "mul_u64_u64_div_u64: new implementation" by Nicolas Pitre, with
assistance from Uwe Kleine-König. Reimplement mul_u64_u64_div_u64()
to provide (much) more accurate results. The current implementation
was causing Uwe some issues in the PWM drivers.
- "xz: Updates to license, filters, and compression options" from
Lasse Collin. Miscellaneous maintenance and kinor feature work to
the xz decompressor.
- "Fix some GDB command error and add some GDB commands" from
Kuan-Ying Lee. Fixes and enhancements to the gdb scripts.
- "treewide: add missing MODULE_DESCRIPTION() macros" from Jeff
Johnson. Adds lots of MODULE_DESCRIPTIONs, thus fixing lots of
warnings about this.
- "nilfs2: add support for some common ioctls" from Ryusuke Konishi.
Adds various commonly-available ioctls to nilfs2.
- "This series fixes a number of formatting issues in kernel doc
comments" from Ryusuke Konishi does that.
- "nilfs2: prevent unexpected ENOENT propagation" from Ryusuke
Konishi. Fix issues where -ENOENT was being unintentionally and
inappropriately returned to userspace.
- "nilfs2: assorted cleanups" from Huang Xiaojia.
- "nilfs2: fix potential issues with empty b-tree nodes" from Ryusuke
Konishi fixes some issues which can occur on corrupted nilfs2
filesystems.
- "scripts/decode_stacktrace.sh: improve error reporting and
usability" from Luca Ceresoli does those things"
