On hardware architectures where a single CAMNOC module is split into
two, one for each of the real time (RT) and non real time (NRT) modules
within camera sub system, processing VFE output over the AXI bus
requires enabling and setting the appropriate clock rate for the RT
CAMNOC. This change lays the groundwork for supporting such
configurations.

Replace the hardcoded buffer count value with a macro to enable
operating on these buffers elsewhere in the CAMSS driver based on this
count. Some of the hardware architectures require deferring the AUP and
REG update until after the CSID configuration and this macro is expected
to be useful in such scenarios.

The static TPDM function as a dummy source, however, it is essential
to enable the port connected to the TPDA and configure the element size.
Without this, the TPDA cannot correctly receive trace data from the
static TPDM. Since the static TPDM does not require MMIO mapping to
access its registers, a clock controller is not mandatory for its
operation.

Currently, the ctl_name string is statically assigned based on the family and
model of the SOC when the amd64_edac module is loaded.
The same, however, is not exactly needed as the string can be generated and
assigned at runtime through scnprintf().
Remove all static assignments and generate the string at runtime. Also,
cleanup the switch cases which became defunct and consolidate identical cases.

Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>:
This series adds support for three new MediaTek PMICs: MT6316, MT6363
and MT6373 and their variants - used in board designs featuring the
MediaTek MT8196 Chromebook SoC, or the MT6991 Dimensity 9400 Smartphone
SoC.
In particular, MT6316 is a regulator, but the MT6363 and MT6373 PMICs
are multi-function devices, as they have and expose multiple sub-devices;
moreover, some of those also contain an interrupt controller, managing
internal IPs interrupts: for those, a chained interrupt handler is
registered, which parent is the SPMI controller itself.
This series adds support for all of the MT6316 regulator variants and
for MT6363, MT6373 SPMI PMICs and their interrupt controller.

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

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

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

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.

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.

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().

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
zero-initializing 'eng_type'.

rtw89 has several ways of handling TX status report events. The first one
is based on RPP feature which is used by PCIe HCI. The other one depends
on firmware sending a corresponding C2H message, quite similar to what
rtw88 has.
Toggle a bit in the TX descriptor to indicate to the firmware that TX
report for the frame is expected. This will allow handling TX wait skbs
and the ones flagged with IEEE80211_TX_CTL_REQ_TX_STATUS correctly.
Do the bulk of the patch according to the vendor driver for RTL8851BU.
However, there are slight differences in C2H message format between
different types of chips. RTL885xB ones follow format V0. RTL8852C has
format V1, and RTL8922AU has format V2.

The qm_get_qos_value() function calls bus_find_device_by_name() which
increases the device reference count, but fails to call put_device()
to balance the reference count and lead to a device reference leak.
Add put_device() calls in both the error path and success path to
properly balance the reference count.
Found via static analysis.

Pass TX status value directly into rtw89_core_tx_wait_complete(). This
will make it a bit in sync with further patches and will give flexibility
in future work. Also use scope based RCU locking which simplifies the

rtw89_usb_ops_tx_kick_off() may need to release skb if a failure occurs.
It operates mainly on skbs coming from the core wireless stack and the
ones containing firmware commands.
Use ieee80211_free_txskb() for the former case.

Cross timestamping is supported on Agilex5 platform with Synchronized
Multidrop Timestamp Gathering(SMTG) IP. The hardware cross-timestamp
result is made available the applications through the ioctl call
PTP_SYS_OFFSET_PRECISE, which inturn calls stmmac_getcrosststamp().
Device time is stored in the MAC Auxiliary register. The 64-bit System
time (ARM_ARCH_COUNTER) is stored in SMTG IP. SMTG IP is an MDIO device
with 0xC - 0xF MDIO register space holds 64-bit system time.
This commit is similar to following commit for Intel platforms:

Agilex5 HPS EMAC uses the dwxgmac-3.10a IP, unlike previous socfpga
platforms which use dwmac1000 IP. Due to differences in platform
configuration, Agilex5 requires a distinct setup.
Introduce a setup_plat_dat() callback in socfpga_dwmac_ops to handle
platform-specific setup. This callback is invoked before
stmmac_dvr_probe() to ensure the platform data is correctly
configured. Also, implemented separate setup_plat_dat() callback for
current socfpga platforms and Agilex5.
