bacd713145 media: i2c: mt9v111: fix incorrect type for ret
Change "ret" from unsigned int to int type in mt9v111_calc_frame_rate()
to store negative error codes or zero returned by __mt9v111_hw_reset()
and other functions.

Storing the negative error codes in unsigned type, doesn't cause an issue
at runtime but it's ugly as pants.

No effect on runtime.

075710b670 media: i2c: mt9p031: fix mbus code initialization
The mediabus code is device dependent, but the probe() function
thought that device_get_match_data() would return the code directly,
when in fact it returned a pointer to a struct mt9p031_model_info.

As a result, the initial mbus code was garbage.

Tested with a BeagleBoard xM and a Leopard Imaging LI-5M03 sensor board.

fc2aaf2d93 media: venus: core: Add qcm2290 DT compatible and resource data
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.

It supports hardware-accelerated decoding of H.264, HEVC, and VP9 formats,

This commit prepares the framework to enable the AR50_LITE (it does not

93f213b444 media: venus: firmware: Use correct reset sequence for IRIS2
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 c38610f898 ("media: venus: firmware: Sanitize
per-VPU-version").

945f500361 perf symbols: Handle 'N' symbols in /proc/kallsyms
I started seeing this in recent Fedora 42 kernels:

  # uname -a
  Linux number 6.16.3-200.fc42.x86_64 #1 SMP PREEMPT_DYNAMIC Sat Aug 23 17:02:17 UTC 2025 x86_64 GNU/Linux
  #
  # perf test vmlinux
    1: vmlinux symtab matches kallsyms                  : FAILED!
  #

Rust is enabled and these were the symbols causing the above failure,
i.e. found in vmlinux but not in /proc/kallsyms:

  $ grep -w N /proc/kallsyms
  0000000000000000 N __pfx__RNCINvNtNtNtCsbDUBuN8AbD4_4core4iter8adapters3map12map_try_foldjNtCs6vVzKs5jPr6_12drm_panic_qr7VersionuINtNtNtBa_3ops12control_flow11ControlFlowB10_ENcB10_0NCINvNvNtNtNtB8_6traits8iterator8Iterator4find5checkB10_NCNvMB12_B10_13from_segments0E0E0B12_

So accept those 'N' symbols as well.

About them, from 'man nm':

           "N" The symbol is a debugging symbol.

           "n" The symbol is in a non-data, non-code, non-debug read-only section.

spi: cadence-quadspi: Flush posted register writes before DAC access
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.

ba9d484ed3 PCI/MSI: Remove the conditional parent [un]mask logic
Now that msi_lib_init_dev_msi_info() overwrites the irq_[un]mask()
callbacks when the MSI_FLAG_PCI_MSI_MASK_PARENT flag is set by the parent

f09c1d63e8 irqchip/msi-lib: Honor the MSI_FLAG_PCI_MSI_MASK_PARENT flag
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.

[ tglx: Adopted to the PCI/MSI changes ]

A value of 10 is not valid for "mediatek,pull-down-adv" and
"mediatek,pull-up-adv" properties which have defined values of 0-3. It
appears the "10" was written as a binary value. The driver only looks at
the lowest 2 bits, so the value "10" decimal works out the same as if
"2" was used.
