Downstream driver uses dpu->caps->smart_dma_rev to update
sspp->cap->features with the bit corresponding to the supported SmartDMA
version. Upstream driver does not do this, resulting in SSPP subdriver
not enabling setup_multirect callback. Add corresponding SmartDMA SSPP
feature bits to dpu hw catalog.
Per Abhinav's request enable the SmartDMA features only on the platforms
where the multirect was actually verified visually (sdm845 and sm8250).
An (untested) enablement on the rest of the platforms comes in the next
patch.

The sspp pointer is set at the dpu_plane_reset(), since this is the

plane<->SSPP relationship, the SSPP will be allocated dynamically in the

Declaring only XR30 but not AR30 color format support can trigger bugs in

10-bit color formats, rendering a 1cm^2 black box around the cursor due to
missing per-pixel alpha-blending.

Currently, DPU will enable TE during prepare_commit(). However, this
will cause a crash and reboot to sahara when trying to read/write to
register in get_autorefresh_config(), because the core clock rates
aren't set at that time.
This used to work because phys_enc->hw_pp is only initialized in mode
set [1], so the first prepare_commit() will return before any register
read/write as hw_pp would be NULL.
However, when we try to implement support for INTF TE, we will run into
the clock issue described above as hw_intf will *not* be NULL on the
first prepare_commit(). This is because the initialization of
dpu_enc->hw_intf has been moved to dpu_encoder_setup() [2].
To avoid this issue, let's enable TE during prepare_for_kickoff()
instead as the core clock rates are guaranteed to be set then.
Depends on: "Implement tearcheck support on INTF block" [3]

The adreno_load_gpu() path is guarded by an error check on
adreno_load_fw(). This function is responsible for loading
Qualcomm-only-signed binaries (e.g. SQE and GMU FW for A6XX), but it
does not take the vendor-signed ZAP blob into account.
By embedding the SQE (and GMU, if necessary) firmware into the
initrd/kernel, we can trigger and unfortunate path that would not bail
out early and proceed with gpu->hw_init(). That will fail, as the ZAP
loader path will not find the firmware and return back to
adreno_load_gpu().
This error path involves pm_runtime_put_sync() which then calls idle()
instead of suspend(). This is suboptimal, as it means that we're not
going through the clean shutdown sequence. With at least A619_holi, this
makes the GPU not wake up until it goes through at least one more
start-fail-stop cycle. The pm_runtime_put_sync that appears in the error
path actually does not guarantee that because of the earlier enabling of
runtime autosuspend.
Fix that by using pm_runtime_put_sync_suspend to force a clean shutdown.
Test cases:
1. All firmware baked into kernel
2. error loading ZAP fw in initrd -> load from rootfs at DE start
Both succeed on A619_holi (SM6375) and A630 (SDM845).

The commit e25e92e08e ("drm/msm: devcoredump iommu fault support")
enabled SMMU stalling to collect GPU state, but only for a6xx. It tied
enabling the stall with tha per-instance pagetables creation.
Since that commit SoCs with a5xx also gained support for
adreno-smmu-priv. Move stalling into generic code and add corresponding
resume_translation calls.
