drm/amd/display: Add DPP & HUBP reset if power gate enabled on DCN314

[WHY]
On DCN314, using full screen application with enabled scaling like 150%,
175%, with overlay cursor, causes a second cursor to appear when changing
planes. Dpp cache is used to track the HW cursor enable. Since power gate
is disabled for hubp & dpp in DCN314, dpp_reset() zero'ed the dpp struct,
while the dpp hardware was not power gated.

So, when plane is changed in a full screen app, and the overlay cursor is
enabled, the cache is cleared, so the cache does not represent the actual
cursor state.

[HOW]
Added conditionals for dpp & hubp reset and their pg_control functions
only if according power_gate flags are enabled.

drm/amd/display: Fix Link Override Sequencing When Switching Between DIO/HPO

[WHY]
When performing certain link maintenance compliance tests or forcing link
settings, changing between 128b/132b and 8b/10b rates no longer works on
some ASICs. Some rate divider updates only occur when we set
timings or validate state, which is not performed currently when toggling
DPMS to change rates.

[HOW]
Re-calculate dividers and reprogram audio when switching between DIO
and HPO through DP compliance/escape code path.
Add OTG disable/re-enable so we don't touch the clock while OTG is active.
Acquire dcLock before forcing link settings to avoid thread synchronization
errors due to added programming in escape code path and potential HPD
interrupts.

drm/amdgpu: fix slab-use-after-free in amdgpu_userq_mgr_fini+0x70c

The issue was reproduced on NV10 using IGT pci_unplug test.
It is expected that `amdgpu_driver_postclose_kms()` is called prior to `amdgpu_drm_release()`.
However, the bug is that `amdgpu_fpriv` was freed in `amdgpu_driver_postclose_kms()`, and then
later accessed in `amdgpu_drm_release()` via a call to `amdgpu_userq_mgr_fini()`.
As a result, KASAN detected a use-after-free condition, as shown in the log below.
The proposed fix is to move the calls to `amdgpu_eviction_fence_destroy()` and
`amdgpu_userq_mgr_fini()` into `amdgpu_driver_postclose_kms()`, so they are invoked before
`amdgpu_fpriv` is freed.

This also ensures symmetry with the initialization path in `amdgpu_driver_open_kms()`,
where the following components are initialized:
- `amdgpu_userq_mgr_init()`
- `amdgpu_eviction_fence_init()`
- `amdgpu_ctx_mgr_init()`

Correspondingly, in `amdgpu_driver_postclose_kms()` we should clean up using:
- `amdgpu_userq_mgr_fini()`
- `amdgpu_eviction_fence_destroy()`
- `amdgpu_ctx_mgr_fini()`

This change eliminates the use-after-free and improves consistency in resource management between open and close paths.

drm/amd/display: Include EQU Prefetch Bandwidth For Bandwidth Calculations

[Why]
Pixel data bandwidth required in mode programming (MP) ends up being
higher than what was calculated in mode support (MS) even though
the prefetch bandwidths calculated in MP are lower than the MS ones.

MP used a different equ prefetch schedule than MS which lead a
slight difference in parameters. This resulted in the pixel data
bandwidth in MP to be higher than MS.

[How]
Rename the RequiredPrefetchBWOTO term so it can be applied generically.
Update the value with the EQU bandwidth if the EQU schedule is used.
Get the max prefetch bandwidth that MS calculated and use it
as part of the calculations for required bandwidth.

Enable the cleaner shader for other GFX9.x series of GPUs to provide
data isolation between GPU workloads. The cleaner shader is responsible
for clearing the Local Data Store (LDS), Vector General Purpose

helps prevent data leakage and ensures accurate computation results.

between processes and maintains a consistent GPU state across KGD and

drm/panfrost: Add support for Mali on the MT8370 SoC

Add a compatible for the MediaTek MT8370 SoC, with an integrated ARM
Mali G57 MC2 GPU (Valhall-JM, dual core), with new platform data for
its support in the panfrost driver.
It uses the same data as MT8186 for the power management features to
describe power supplies, pm_domains and enablement (one regulator, two
power domains) but also sets the FORCE_AARCH64_PGTABLE flag in the GPU
configuration quirks bitfield to enable AARCH64 4K page table format
mode.
As MT8186 and MT8370 SoC have different GPU architecture (Mali G52 2EE
MC2 for MT8186), making them not compatible, and this mode is only
enabled for Mediatek SoC that are Mali G57 based (compatible with
mediatek,mali-mt8188 or mediatek,mali-8192), having specific platform
data allows to set this flag for MT8370 without modifying MT8186
configuration and behaviour.

drm/panfrost: Commonize Mediatek power domain array definitions

In the panfrost driver, the platform data of several Mediatek SoC
declares and uses several different power domains arrays according to
GPU core number present in the SoC:
- mediatek_mt8186_pm_domains (2 cores)
- mediatek_mt8183_pm_domains (3 cores)
- mediatek_mt8192_pm_domains (5 cores)

As they all are fixed arrays, starting with the same entries and the
platform data also has a power domains array length field
(num_pm_domains), they can be replaced by a single array, containing
all entries, if the num_pm_domains field of the platform data is also
set to the matching core number.

So, create a generic power domain array (mediatek_pm_domains) and use
it in the mt8183(b), mt8186, mt8188 and mt8192 platform data instead.

So drop these duplicated definitions and use default_supplies instead.
Also, rename mediatek_mt8183_supplies to a more generic name too
(legacy_supplies).

drm/bridge: tc358767: convert to devm_drm_bridge_alloc() API

This is the new API for allocating DRM bridges.

Converting this driver is a bit complex because the drm_bridge funcs
pointer differs based on the bridge mode. So the current code does:

 * tc_probe()
   * devm_kzalloc() private struct embedding drm_bridge
   * call tc_probe_bridge_endpoint() which
     * parses DT description into struct fields
     * computes the mode
     * calls different bridge init functions based on the mode
       * each sets a different bridge.funcs pointer

The new API expects the funcs pointer to be known at alloc time, which does
not fit in the current code structure.

Solve this by splitting tc_probe_bridge_endpoint() in two functions:

 * tc_probe_get_mode(), computing the mode without needing the private
   driver structure
 * tc_probe_bridge_endpoint(), only initializing the endpoints

So now the mode is known before allocation and so
is the funcs pointer, while all other operations are still happening after
allocation, directly into the private struct data, as they used to.

The new code flow is:

 * tc_probe()
   * tc_probe_get_mode()
     * parses DT description
     * computes and returns the mode
   * based onf the mode, pick the funcs pointer
   * devm_drm_bridfge_alloc(..., funcs)
   * call tc_probe_bridge_endpoint() which
     * calls different bridge init functions based on the mode
       * these don't set the funcs pointer, it was done by _alloc

This solution is chosen to minimize the changes in the driver logical code
flow. The drawback is we now iterate twice over the endpoints during probe.
