Starting with commit f99508074e78 ("PM: domains: Detach on
device_unbind_cleanup()"), there is no longer a need to call
dev_pm_domain_detach() in the bus remove function. The
device_unbind_cleanup() function now handles this to avoid
invoking devres cleanup handlers while the PM domain is
powered off, which could otherwise lead to failures as
described in the above-mentioned commit.
Drop the explicit dev_pm_domain_detach() call and rely instead
on the flags passed to dev_pm_domain_attach() to power off the
domain.

k3_rproc_request_mbox()
If an error occurs after a successful k3_rproc_request_mbox() call,
mbox_free_channel() should be called to avoid a leak.
Such a call is missing in the error handling path of k3_dsp_rproc_probe().
It is also missing both in the error handling path of k3_m4_rproc_probe()
and in the (in-existent) corresponding remove function.
Switch to managed resources to avoid these leaks and simplify the code.
Remove the now unneeded mbox_free_channel().

Change the 'ret' variable from u32 to int to store -EINVAL. Storing the
negative error codes in unsigned type, doesn't cause an issue at runtime
but it's ugly as pants.
Additionally, assigning -EINVAL to u32 ret (i.e., u32 ret = -EINVAL) may
trigger a GCC warning when the -Wsign-conversion flag is enabled.

[why]
Read link setting inside mode validation is not always the final downlink setting.
It is found true in Synaptics branch device.
At bootup, the preferred mode being set right after 1080p is set. It occurred
before graphic load. That modeset switch in a short period of time makes
the branch device switch back and forth from lower and higher link rate,
observed at Synaptics branch device.
DP2 RTK hub on the other hand, sticks to highest available downlink rate after bootup.
Existing check of runtime downlink setting in mode validation shows asynchronous at
branch device link switch, i.e., downlink switch to higher link rate not yet complete
when the mode validation tries to probe the downlink setting. That makes mode validation
checking downlink setting making wrong decision by pruning modes that should pass the
validation after the downlink setting switch is complete.
[how]
If Synaptics is found at the last branch, skip checking downlink setting
at mode validation.

[Why]
Bounding box values can be stored in multiple locations. (e.g. PMFW, VBIOS, DMUB).
The source and interpretation of these values can vary with DCN revision
so there should be a component that can gather these values and translate
them accordingly
[How]
Have component start with the statically defined values as a base.
Then update them as needed with DCN-specific logic
Guard this component with FPU flags since values need to be in float point.

The patch uses power state of VCN instances for requesting video
profile.
In idle worker of a vcn instance, when there is no outstanding
submisssion or fence, the instance is put to power gated state. When
all instances are powered off that means video profile is no longer
required. A request is made to turn off video profile.
A job submission starts with begin_use of ring, and at that time
vcn instance state is changed to power on. Subsequently a check is
made for active video profile, and if not active, a request is made.

The fans controlled by the driver can get stuck at 0 RPM if they are
configured below a 20% duty cycle. The driver tries to avoid this by
enforcing a minimum duty cycle of 20%, but this is done after the fans
are registered with the thermal subsystem. This is too late as the
thermal subsystem can set their current state before the driver is able
to enforce the minimum duty cycle.
Fix by setting the minimum duty cycle before registering the fans with
the thermal subsystem.

If an object is backed up to shmem it is incorrectly identified
as not having valid data by the move code. This means moving
to VRAM skips the -EMULTIHOP step and the bo is cleared. This
causes all sorts of weird behaviour on DGFX if an already evicted
object is targeted by the shrinker.
Fix this by using ttm_tt_is_swapped() to identify backed-up
objects.

The per-fd reset counter tracks GPU resets caused by jobs submitted
through a specific file descriptor. However, there's a race condition
where the file descriptor can be closed while jobs are still running,
leading to potential access to freed memory when updating the reset
counter.
Ensure that the per-fd reset counter is only updated when the file
descriptor is still valid, preventing use-after-free scenarios during
GPU reset handling.

CPU jobs and CACHE CLEAN jobs execute synchronously once the DRM
scheduler starts running them. Therefore, there is no fence to wait on,
neither are those jobs able to timeout.
Hence, remove the `timedout_job` hook from the CPU and CACHE CLEAN
scheduler ops.

When the file descriptor is closed while a job is still running,
there's a race condition between the job completion callback and the
file descriptor cleanup. This can lead to accessing freed memory when

Fix such an issue by protecting all accesses to `job->file_priv` with
the queue's lock. With that, we can clear `job->file_priv` before the
V3D per-fd structure is freed and assure that `job->file_priv` exists
during the per-fd GPU stats updates.

Each V3D queue works independently and all the dependencies between the
jobs are handled through the DRM scheduler. Therefore, there is no need
to use one single lock for all queues. Using it, creates unnecessary
contention between different queues that can operate independently.
Replace the global spinlock with per-queue locks to improve parallelism
and reduce contention between different V3D queues (BIN, RENDER, TFU,
CSD). This allows independent queues to operate concurrently while
maintaining proper synchronization within each queue.

Instead of storing the queue's active job in four different variables,
store the active job inside the queue's state. This way, it's possible
to access all active jobs using an index based in `enum v3d_queue`.

Instead of storing a pointer to the DRM file data, store a pointer
directly to the private V3D file struct. No functional change, this
commit only avoids multiple levels of pointer indirection and makes
the code more straightforward.

package ID
Currently, tpmi_get_logical_id() calls topology_physical_package_id()
to set the pkg_id of the info structure. Since some VM hosts assign non
contiguous package IDs, topology_physical_package_id() can return a
larger value than topology_max_packages(). This will result in an
invalid reference into tpmi_power_domain_mask[] as that is allocatead
based on topology_max_packages() as the maximum package ID.

supports_op callback
In commit 13529647743d9 ("spi: microchip-core-qspi: Support per spi-mem
operation frequency switches") the logic for checking the viability of
op->max_freq in mchp_coreqspi_setup_clock() was copied into
mchp_coreqspi_supports_op(). Unfortunately, op->max_freq is not valid
when this function is called during probe but is instead zero.
Accordingly, baud_rate_val is calculated to be INT_MAX due to division
by zero, causing probe of the attached memory device to fail.
Seemingly spi-microchip-core-qspi was the only driver that had such a
modification made to its supports_op callback when the per_op_freq
capability was added, so just remove it to restore prior functionality.
