2023-06-18drm/msm/a6xx: Move a6xx_bus_clear_pending_transactions to a6xx_gpuKonrad Dybcio
This function is responsible for telling the GPU to halt transactions on all of its relevant buses, drain them and leave them in a predictable state, so that the GPU can be e.g. reset cleanly. Move the function to a6xx_gpu.c, remove the static keyword and add a prototype in a6xx_gpu.h to accomodate for the move.

2023-06-18drm/msm/a6xx: Move force keepalive vote removal to a6xx_gmu_force_off()Konrad Dybcio
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.

2023-06-18dt-bindings: display/msm/gmu: Add GMU wrapperKonrad Dybcio
The "GMU Wrapper" is Qualcomm's name for "let's treat the GPU blocks we'd normally assign to the GMU as if they were a part of the GMU, even though they are not". It's a (good) software representation of the GMU_CX and GMU_GX register spaces within the GPUSS that helps us programatically treat these de-facto GMU-less parts in a way that's very similar to their GMU-equipped cousins, massively saving up on code duplication. The "wrapper" register space was specifically designed to mimic the layout of a real GMU, though it rather obviously does not have the M3 core et al. To sum it all up, the GMU wrapper is essentially a register space within the GPU, which Linux sees as a dumbed-down regular GMU: there's no clocks, interrupts, multiple reg spaces, iommus and OPP. Document it.

2023-06-15drm/msm/dp: Free resources after unregistering themBjorn Andersson
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.

2023-06-15drm/msm/dp: Drop aux devices together with DP controllerBjorn Andersson
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.

2023-06-15drm/msm/dsi: Remove incorrect references to slice_countJessica Zhang
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 010c8bbad2cb ("drm: msm: adreno: Disable preemption on Adreno 510") added special handling for a510 (this SKU doesn't seem to support 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.
