On some MediaTek SoCs, an Audio DSP (ADSP) is integrated as a separate
hardware block that leverages Sound Open Firmware (SOF) and provides
additional audio functionalities. This hardware is optional, and the
audio subsystem will still function normally when it's not present.
To enable ADSP support, a 'mediatek,adsp' property is required in the
sound card node to pass the ADSP phandle. This allows AFE to link to
ADSP when the sound card is probed.
MT8188 has ADSP integrated, so add the 'mediatek,adsp' property to
allow using it in the audio subsystem.
This fixes dtbs_check error:
Unevaluated properties are not allowed ('mediatek,adsp' was
unexpected)

In some complex scenarios, we deploy multiple tasks on a single machine
(hybrid deployment), such as Docker containers for function computation
(background processing), real-time tasks, monitoring, event handling,
and management, along with an NVMe target server.
Each of these components is restricted to its own CPU cores to prevent
mutual interference and ensure strict isolation. To achieve this level
of isolation for nvmet_wq we need to use sysfs tunables such as
cpumask that are currently not accessible.
Add WQ_SYSFS flag to alloc_workqueue() when creating nvmet_wq so
workqueue tunables are exported in the userspace via sysfs.

This commit adds the cleaner shader microcode for GFX11.0.3 GPUs. The
cleaner shader is a piece of GPU code that is used to clear or
initialize certain GPU resources, such as Local Data Share (LDS), Vector
General Purpose Registers (VGPRs), and Scalar General Purpose Registers
(SGPRs).
Clearing these resources is important for ensuring data isolation
between different workloads running on the GPU. Without the cleaner
shader, residual data from a previous workload could potentially be
accessed by a subsequent workload, leading to data leaks and incorrect
computation results.
The cleaner shader microcode is represented as an array of 32-bit words
(`gfx_11_0_3_cleaner_shader_hex`). This array is the binary
representation of the cleaner shader code, which is written in a
low-level GPU instruction set.
When the cleaner shader feature is enabled, the AMDGPU driver loads this
array into a specific location in the GPU memory. The GPU then reads
this memory location to fetch and execute the cleaner shader
instructions.
The cleaner shader is executed automatically by the GPU at the end of
each workload, before the next workload starts. This ensures that all
GPU resources are in a clean state before the start of each workload.
This addition is part of the cleaner shader feature implementation. The
cleaner shader feature helps resource utilization by cleaning up GPU
resources after they are used. It also enhances security and reliability
by preventing data leaks between workloads.

On J7 platforms, setting up multiple RX flows was failing
as the RX free descriptor ring 0 is shared among all flows
and we did not allocate enough elements in the RX free descriptor
ring 0 to accommodate for all RX flows.
This issue is not present on AM62 as separate pair of
rings are used for free and completion rings for each flow.
Fix this by allocating enough elements for RX free descriptor
ring 0.
However, we can no longer rely on desc_idx (descriptor based
offsets) to identify the pages in the respective flows as
free descriptor ring includes elements for all flows.
To solve this, introduce a new swdata data structure to store
flow_id and page. This can be used to identify which flow (page_pool)
and page the descriptor belonged to when popped out of the
RX rings.

It looks like commit c6ca1ac9f4 ("thunderbolt: Increase sideband

than what might be expected by the dock (although there is no such limit
in the USB4 spec) which probably makes it assume there is something

For this reason lower the sideband access delay from 5ms to 1ms. This

Armv8.9/v9.4 introduces the feature Hardware managed Access Flag
for Table descriptors (FEAT_HAFT). The feature is indicated by
ID_AA64MMFR1_EL1.HAFDBS == 0b0011 and can be enabled by
TCR2_EL1.HAFT so it has a dependency on FEAT_TCR2.
Adds the Kconfig for FEAT_HAFT and support detecting and enabling
the feature. The feature is enabled in __cpu_setup() before MMU on
just like HA. A CPU capability is added to notify the user of the
feature.
Add definition of P{G,4,U,M}D_TABLE_AF bit and set the AF bit
when creating the page table, which will save the hardware
from having to update them at runtime. This will be ignored if
FEAT_HAFT is not enabled.
The AF bit of table descriptors cannot be managed by the software
per spec, unlike the HA. So this should be used only if it's supported
system wide by system_supports_haft().
