The OmniVision OG01A1B image sensor is a monochrome sensor, it supports
8-bit and 10-bit RAW output formats only.
That said the planar greyscale Y8/Y10 media formats are more appropriate
for the sensor instead of the originally and arbitrary selected SGRBG one,
since there is no red, green or blue color components.

The mediabus code is device dependent, but the probe() function

Add a qcm2290 compatible binding to the Venus core.
The maximum concurrency is video decode at 1920x1080 (FullHD) with video
encode at 1280x720 (HD).
The driver is not available to firmware versions below 6.0.55 due to an
internal requirement for secure buffers.
The bandwidth tables incorporate a conservative safety margin to ensure
stability under peak DDR and interconnect load conditions.

When starting venus with the "no_tz" code path, IRIS2 needs the same
boot/reset sequence as IRIS2_1. This is because most of the registers were
moved to the "wrapper_tz_base", which is already defined for both IRIS2 and
IRIS2_1 inside core.c. Add IRIS2 to the checks inside firmware.c as well to
make sure that it uses the correct reset sequence.
Both IRIS2 and IRIS2_1 are HFI v6 variants, so the correct sequence was
used before commit c38610f8981e ("media: venus: firmware: Sanitize
per-VPU-version").

cqspi_read_setup() and cqspi_write_setup() program the address width as
the last step in the setup. This is likely to be immediately followed by
a DAC region read/write. On TI K3 SoCs the DAC region is on a different
endpoint from the register region. This means that the order of the two
operations is not guaranteed, and they might be reordered at the
interconnect level. It is possible that the DAC read/write goes through
before the address width update goes through. In this situation if the
previous command used a different address width the OSPI command is sent
with the wrong number of address bytes, resulting in an invalid command
and undefined behavior.
Read back the size register to make sure the write gets flushed before
accessing the DAC region.

cqspi_indirect_read_execute() and cqspi_indirect_write_execute() first

means that the order of the two operations is not guaranteed, and they
might be reordered at the interconnect level.
It is possible for the AHB write to be executed before the APB write to
enable the indirect controller, causing the transaction to be invalid
and the write erroring out. Read back the APB region write before
accessing the AHB region to make sure the write got flushed and the race

For systems that implement interrupt masking at the interrupt controller
level, the MSI library offers MSI_FLAG_PCI_MSI_MASK_PARENT. It indicates
that it isn't enough to only unmask the interrupt at the PCI device level,
but that the interrupt controller must also be involved.
However, the way this is currently done is less than optimal, as the
masking/unmasking is done on both sides, always. It would be far cheaper to
unmask both at the start of times, and then only deal with the interrupt
controller mask, which is cheaper than a round-trip to the PCI endpoint.
Now that the PCI/MSI layer implements irq_startup() and irq_shutdown()
callbacks, which [un]mask at the PCI level and honor the request to
[un]mask the parent, this can be trivially done.
Overwrite the irq_mask/unmask() callbacks of the device domain interrupt
chip with irq_[un]mask_parent() when the parent domain asks for it.

The cpufreq_cpu_put() call in update_qos_request() takes place too early
because the latter subsequently calls freq_qos_update_request() that
indirectly accesses the policy object in question through the QoS request
object passed to it.
Fortunately, update_qos_request() is called under intel_pstate_driver_lock,
so this issue does not matter for changing the intel_pstate operation
mode, but it theoretically can cause a crash to occur on CPU device hot
removal (which currently can only happen in virt, but it is formally
supported nevertheless).
Address this issue by modifying update_qos_request() to drop the
reference to the policy later.

The i.MX SCMI MISC protocol can report board information from the
System Manager (SM), including a board name and board-specific
attributes. Query this during protocol initialization.
If the firmware does not implement BOARD_INFO, handle -EOPNOTSUPP
gracefully and continue.

AST2700 continues the multi-instance SCU interrupt controller model
introduced in the AST2600, with four independent interrupt domains (scu-ic0
to 3).
Unlike earlier generations which combine interrupt enable and status bits
into a single register, AST2700 separates these into distinct IER and ISR
registers. Support for this layout is implemented by using register offsets
and separate chained IRQ handlers.
The variant table is extended to cover AST2700 IC instances, enabling
shared initialization logic while preserving support for previous SoCs.

The SCU IC driver handles each AST2600 instance with separate
initialization functions and hardcoded register definitions, which is
inflexible and creates duplicated code.
Consolidate the implementation by introducing a variant-based structure,
selected via compatible string, and use a unified init path and MMIO access
via of_iomap(). This simplifies the code and prepares for upcoming SoCs
like AST2700, which require split register handling.

Code in gicv5_its_irq_domain_alloc() has two issues:
- it checks the wrong return value/variable when calling gicv5_alloc_lpi()
- The cleanup code does not take previous loop iterations into account
Fix both issues at once by adding the right gicv5_alloc_lpi() variable
check and by reworking the function cleanup code to take into account
current and previous iterations.

The "i" variable in gicv5_its_create_itt_two_level() needs to be signed
otherwise it can cause a forever loop in the function's cleanup path.
