After restructuring and splitting the HDMI codec driver code, each
HDMI codec driver contains the own build_controls and build_pcms ops.
A copy-n-paste error put the wrong entries for nvhdmi-mcp driver; both
build_controls and build_pcms are swapped. Unfortunately both
callbacks have the very same form, and the compiler didn't complain
it, either. This resulted in a NULL dereference because the PCM
instance hasn't been initialized at calling the build_controls
callback.
Fix it by passing the proper entries.

Add sanity check in iris_vb2_stop_streaming. If inst->state is
already IRIS_INST_ERROR, we should skip the stream_off operation
because it would still send packets to the firmware.
In iris_kill_session, inst->state is set to IRIS_INST_ERROR and
session_close is executed, which will kfree(inst_hfi_gen2->packet).
If stop_streaming is called afterward, it will cause a crash.

Improve the condition used to determine when input internal buffers need
to be reconfigured during streamon on the capture port. Previously, the
check relied on the INPUT_PAUSE sub-state, which was also being set
during seek operations. This led to input buffers being queued multiple
times to the firmware, causing session errors due to duplicate buffer
submissions.
This change introduces a more accurate check using the FIRST_IPSC and
DRC sub-states to ensure that input buffer reconfiguration is triggered
only during resolution change scenarios, such as streamoff/on on the
capture port. This avoids duplicate buffer queuing during seek
operations.

As a part of migrating code from the old Venus driver to the new Iris
one, add support for the SC7280 platform. It is very similar to SM8250,
but it (currently) uses no reset controls (there is an optional
GCC-generated reset, it will be added later) and no AON registers
region. Extend the VPU ops to support optional clocks and skip the AON
shutdown for this platform.

Now as we have removed PIPE value from inst_fw_caps_dec there should be
no difference between inst_fw_caps of QCS8300 and SM8550+. Drop the
QCS8300-specific tables and use generic one instead.
The differences between QCS8300 and SM8550 data comes from a
non-conflict merge of commit d22037f3fd33 ("media: iris: Set platform
capabilities to firmware for encoder video device") (which added .set
callbacks), and commit 6bdfa3f947a7 ("media: iris: Add platform-specific
capabilities for encoder video device") (which added QCS8300 data, but
not the callbacks).

The value of the PIPE property depends on the number of pipes available
on the platform and is frequently the only difference between several
fw_caps. In order to reduce duplication, use num_vpp_pipe from the
iris_platform_data rather than hardcoding the value into the fw_cap.

The encoder and decoder platform devices are registered by the venus
driver as children of the venus device, but even if someone were to mess
this up no amount of probe deferring is going to conjure up a parent.
Relatedly, the venus driver sets its driver data before registering the
child devices and if this ever breaks we want to learn about it by
failing probe.

Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistentcy cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistentcy cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

system_unbound_wq should be the default workqueue so as not to enforce
locality constraints for random work whenever it's not required.
Adding system_dfl_wq to encourage its use when unbound work should be used.
The old system_unbound_wq will be kept for a few release cycles.

In review of a followup work, Harry noticed a potential infinite loop.
Upon closed inspection, it already exists for kmalloc_nolock() on a
cache with debugging enabled, since commit af92793e52c3 ("slab:
Introduce kmalloc_nolock() and kfree_nolock().")
When alloc_single_from_new_slab() fails to trylock node list_lock, we
keep retrying to get partial slab or allocate a new slab. If we indeed
interrupted somebody holding the list_lock, the trylock fill fail
deterministically and we end up allocating and defer-freeing slabs
indefinitely with no progress.
To fix it, fail the allocation if spinning is not allowed. This is
acceptable in the restricted context of kmalloc_nolock(), especially
with debugging enabled.

TX wait skbs need to be completed when they are done. PCIe part does this
inside rtw89_pci_tx_status() during RPP processing. Other HCIs use a
mechanism based on C2H firmware messages.
Store TX wait skbs inside TX report queue so that it'll be possible to
identify completed items inside the C2H handler. Try to do this as
similar to PCIe path as possible. When the corresponding TX wait skb is
found inside TX report queue, unlink it from there and call
rtw89_core_tx_wait_complete() to mark the completion.
If the callee waiting for the completion has already timed out, the TX
wait skb is placed into TX wait list (like PCIe part does).
It's important that during HCI reset all pending TX wait frames should be
completed inside hci.ops->reset method before calling
rtw89_tx_wait_list_clear().

In order to provide TX reports for the management queue rtw89 should
configure the firmware. Do this with SET_CMC_TBL_MGQ_RPT_EN() for the
WiFi6 chips and with CCTLINFO_G7_W0_MGQ_RPT_EN flag for the WiFi7 ones.

Frames flagged with IEEE80211_TX_CTL_REQ_TX_STATUS mean the driver has to
report to mac80211 stack whether AP sent ACK for the null frame/probe
request or not. It's not implemented in USB part of the driver yet.
PCIe HCI has its own way of getting TX status incorporated into RPP
feature, and it's always enabled there. Other HCIs need a different
scheme based on processing C2H messages.
Thus define a .tx_rpt_enabled flag indicating which HCIs need to enable a
TX report feature. Currently it is USB only.
Toggle a bit in the TX descriptor and place flagged skbs in a fix-sized
queue to wait for a message from the firmware. Firmware maintains a 4-bit
sequence number for required frames hence the queue can contain just 16
elements simultaneously. That's enough for normal driver / firmware
communication. If the firmware crashes for any reason and doesn't provide
TX reports in time, driver will handle this and report the obsolete frames
as dropped.
rtw89 also has a new feature providing a TX report for each transmission
attempt. Ignore a failed TX status reported by the firmware until retry
limit is reached or successful status appears. When there is no success
and the retry limit is reached, report the frame up to the wireless stack
as failed eventually.
HCI reset should stop all pending TX activity so forcefully flush the
queue there.

During HCI reset all pending TX URBs should be canceled. Use anchor to
keep track of them and have an ability to cancel them synchronously.
Note however that canceling RX URBs can't be done here in
rtw89_usb_ops_reset() as it breaks driver initialization.

strcpy() is deprecated; use the safer strscpy() instead.
The destination buffer is only zero-initialized for the first iteration
and since strscpy() guarantees its NUL termination anyway, remove
