30f55f3f23 drm/msm/a6xx: Move CX GMU power counter enablement to hw_init
Since the introduction of A6xx support, we've been enabling the CX GMU
power counter 0 in a bit of a weird spot. Move it to hw_init so that
GMU wrapper GPUs can reuse the same code paths. As a bonus, this order
makes it easier to compare mainline and downstream register access traces.

05a23a76d3 drm/msm/a6xx: Remove both GBIF and RBBM GBIF halt on hw init
Currently we're only deasserting REG_A6XX_RBBM_GBIF_HALT, but we also
need REG_A6XX_GBIF_HALT to be set to 0.

This is typically done automatically on successful GX collapse, but in
case that fails, we should take care of it.

Also, add a memory barrier to ensure it's gone through before jumping
to further initialization.

277b967829 drm/msm/a6xx: Add a helper for software-resetting the GPU
Introduce a6xx_gpu_sw_reset() in preparation for adding GMU wrapper
GPUs and reuse it in a6xx_gmu_force_off().

This helper, contrary to the original usage in GMU code paths, adds
a readback+delay sequence to ensure that the reset is never deasserted
too quickly due to e.g. OoO execution going crazy.

prototype in a6xx_gpu.h to accomodate for the move.

ce8f1381fd drm/msm/a6xx: Move force keepalive vote removal to a6xx_gmu_force_off()
As pointed out by Akhil during the review process of GMU wrapper
introduction [1], it makes sense to move this write into the function
that's responsible for forcibly shutting the GMU off.

It is also very convenient to move this to GMU-specific code, so that
it does not have to be guarded by an if-condition to avoid calling it
on GMU wrapper targets.

Move the write to the aforementioned a6xx_gmu_force_off() to achieve
that. No effective functional change.

fa0048a4b1 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.

a7bfb2ad21 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.

155fa3a91d 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.

The commit 010c8bbad2 ("drm: msm: adreno: Disable preemption on Adreno

preemption, so the driver should clamp nr_rings to 1). However the
gpu->revn is not yet set (it is set later, in adreno_gpu_init()) and
thus the condition is always false. Check config->rev instead.
