drm/msm/dpu: drop separate dpu_core_perf_tune overrides

The values in struct dpu_core_perf_tune are fixed per the core perf
mode. Drop the 'tune' values and substitute them with known values when
performing perf management.

drm/msm/dpu: re-introduce dpu core revision to the catalog

Introduce the dpu core revision back as an entry to the catalog so that
we can just use dpu revision checks and enable those bits which
should be enabled unconditionally and not controlled by a catalog
and also simplify the changes to do something like:

if (dpu_core_revision > xxxxx && dpu_core_revision < xxxxx)
   enable the bit;

changes in v5:
- fix the commit text to remove instances of DPU_HW_VER

drm/msm/dsi: Enable BURST_MODE for command mode for DSI 6G v1.3+

During a frame transfer in command mode, there could be frequent
LP11 <-> HS transitions when multiple DCS commands are sent mid-frame or
if the DSI controller is running on slow clock and is throttled. To
minimize frame latency due to these transitions, it is recommended to
send the frame in a single burst.

This feature is supported for DSI 6G 1.3 and above, thus enable burst
mode if supported.

drm/msm/dpu: Remove redundant prefix/suffix in name of sub-blocks

For a device core dump, the registers of sub-blocks are printed under a
title formatted as <mainBlkName_sblkName>. For example, the csc sub-block
for an SSPP main block "sspp_0" would be printed "sspp_0_sspp_csc0". The
title is clearly redundant due to the duplicate "sspp" and "0" that exist
in both the mainBlkName and sblkName. To eliminate this redundancy, remove
the secondary "sspp" and "0" that exist in the sub-block name by
elimanting the "sspp_" prefix and the concatenation of "num" that results
in the redundant "0" suffix. Remove num parameter altogether from relevant
macros as a consequence of it no longer being used.

drm/msm/dpu: retrieve DSI DSC struct through priv->dsi[0]

Currently struct drm_dsc_config for DSI is populated at display
setup during system boot up. This mechanism works fine with
embedded display but not for pluggable displays as the
struct drm_dsc_config will become stale once external display

In preparation of adding support for DP DSC support
move storing of DSI DSC struct to atomic_enable() so that same
mechanism will work for both embedded display and pluggable

drm/msm/a6xx: Add A610 support

A610 is one of (if not the) lowest-tier SKUs in the A6XX family. It
features no GMU, as it's implemented solely on SoCs with SMD_RPM.
What's more interesting is that it does not feature a VDDGX line
either, being powered solely by VDDCX and has an unfortunate hardware
quirk that makes its reset line broken - after a couple of assert/
deassert cycles, it will hang for good and will not wake up again.

This GPU requires mesa changes for proper rendering, and lots of them
at that. The command streams are quite far away from any other A6XX
GPU and hence it needs special care. This patch was validated both
by running an (incomplete) downstream mesa with some hacks (frames
rendered correctly, though some instructions made the GPU hangcheck
which is expected - garbage in, garbage out) and by replaying RD
traces captured with the downstream KGSL driver - no crashes there,
ever.

Add support for this GPU on the kernel side, which comes down to
pretty simply adding A612 HWCG tables, altering a few values and
adding a special case for handling the reset line.

drm/msm/a6xx: Introduce GMU wrapper support

Some (particularly SMD_RPM, a.k.a non-RPMh) SoCs implement A6XX GPUs
but don't implement the associated GMUs. This is due to the fact that
the GMU directly pokes at RPMh. Sadly, this means we have to take care
of enabling & scaling power rails, clocks and bandwidth ourselves.

Reuse existing Adreno-common code and modify the deeply-GMU-infused
A6XX code to facilitate these GPUs. This involves if-ing out lots
of GMU callbacks and introducing a new type of GMU - GMU wrapper (it's
the actual name that Qualcomm uses in their downstream kernels).

This is essentially a register region which is convenient to model
as a device. We'll use it for managing the GDSCs. The register
layout matches the actual GMU_CX/GX regions on the "real GMU" devices
and lets us reuse quite a bit of gmu_read/write/rmw calls.

drm/msm/dpu: fix sc7280 and sc7180 PINGPONG done interrupts

During IRQ conversion we have lost the PP_DONE interrupts for sc7280
platform. This was left unnoticed, because this interrupt is only used
for CMD outputs and probably no sc7[12]80 systems use DSI CMD panels.

drm/msm/dp: Free resources after unregistering them

The DP component's unbind operation walks through the submodules to
unregister and clean things up. But if the unbind happens because the DP
controller itself is being removed, all the memory for those submodules
has just been freed.

Change the order of these operations to avoid the many use-after-free
that otherwise happens in this code path.

drm/msm/dp: Drop aux devices together with DP controller

Using devres to depopulate the aux bus made sure that upon a probe
deferral the EDP panel device would be destroyed and recreated upon next
attempt.

But the struct device which the devres is tied to is the DPUs
(drm_dev->dev), which may be happen after the DP controller is torn
down.

Indications of this can be seen in the commonly seen EDID-hexdump full
of zeros in the log, or the occasional/rare KASAN fault where the
panel's attempt to read the EDID information causes a use after free on
DP resources.

It's tempting to move the devres to the DP controller's struct device,
but the resources used by the device(s) on the aux bus are explicitly
torn down in the error path. The KASAN-reported use-after-free also
remains, as the DP aux "module" explicitly frees its devres-allocated
memory in this code path.

As such, explicitly depopulate the aux bus in the error path, and in the
component unbind path, to avoid these issues.

proper dirty/damage processing. The drm/msm driver requires that to

drm/msm/dsi: Remove incorrect references to slice_count

Currently, slice_count is being used to calculate word count and
pkt_per_line. Instead, these values should be calculated using slice per
packet, which is not the same as slice_count.

Slice count represents the number of slices per interface, and its value
will not always match that of slice per packet. For example, it is possible
to have cases where there are multiple slices per interface but the panel
specifies only one slice per packet.

Thus, use the default value of one slice per packet and remove slice_count
from the aforementioned calculations.
