85c3453284 i2c: qcom-geni: fix I2C frequency table to achieve accurate bus rates
Update the I2C frequency table to match the recommended values
specified in the I2C hardware programming guide. In the current IPQ5424
configuration where 32MHz is the source clock, the I2C bus frequencies do
not meet expectations—for instance, 363KHz is achieved instead of the
expected 400KHz.

315b40df66 i2c: tegra: Remove dma_sync_*() calls
Calling dma_sync_*() on a buffer from dma_alloc_coherent() is pointless.
The driver should not be doing its own bounce-buffering if the buffer is
allocated through dma_alloc_coherent().

635bf3c885 i2c: tegra: Use internal reset when reset property is not available
For controllers that has an internal software reset, make the reset
property optional. This provides and option to use I2C in systems
that choose to restrict reset control from Linux or not to implement
the ACPI _RST method.

Internal reset was not required when the reset control was mandatory.
But on platforms where the resets are outside the control of Linux,
this had to be implemented by just returning success from BPMP or with
an empty _RST method in the ACPI table, basically ignoring the reset.

While the internal reset is not identical to the hard reset of the
controller, this will reset all the internal state of the controller
including FIFOs. This may slightly alter the behaviour in systems
which were ignoring the reset but it should not cause any functional
difference since all the required I2C registers are configured after
this reset, just as in boot. Considering that this sequence is hit
during the boot or during the I2C recovery path from an error, the
internal reset provides a better alternative than just ignoring the
reset.

ffdd20555c i2c: stm32f7: support i2c_*_dma_safe_msg_buf APIs
`i2c_*_dma_safe_msg_buf` APIs operate on a `struct i2c_msg`.
The get operation make sure the I2C buffer is DMA'able according to its
buffer length, or if the memory use is DMA coherent for example and
return a valid pointer for safe DMA access to be used.
The put operation release the pointer.
Prefer using generic API's than relying on private tests.

78bb43e51b Updates for the generic entry code:
- Split the code into syscall and exception/interrupt parts to ease the
     conversion of ARM[64] to the generic entry infrastructure
 
   - Extend syscall user dispatching to support a single intercepted range
     instead of the default single non-intercepted range. That allows
     monitoring/analysis of a specific executable range, e.g. a library, and
     also provides flexibility for sandboxing scenarios.
 
   - Cleanup and extend the user dispatch selftest

commit c652887a92 ("KVM: arm64: vgic-v3: Allow userspace to write
GICD_TYPER2.nASSGIcap") makes the allocation of vPEs depend on nASSGIcap
for GICv4.1 hosts. While the vGIC v4 initialization and teardown is
handled correctly, it erroneously attempts to establish a vLPI mapping
to a VM that has no vPEs allocated:

       The access is not only horribly slow, as it has to go all the way out
       to the NIC/PTP hardware, but that also prevents the kernel to read

99e731bcb8 A treewide cleanup of struct cycle_counter const annotations:
The initial idea of making them const was correct as they were seperate
  instances. When they got embedded into larger data structures, which are
  even modified by the callback this got moot. The only reason why this went
  unnoticed is that the required container_of() casts the const attribute
  forcefully away.
 
  Stop pretending that it is const.

0b29600a30 Updates for interrupt chip drivers:
- Add support of forced affinity setting to yet offline CPUs for the
    MIPS-GIC to ensure that the affinity of per CPU interrupts can be set
    during the early bringup phase of a secondary CPU in the hotplug code
    before the CPU is set online and interrupts are enabled.\
 
  - Add support for the MIPS (RISC-V !?!?) P8700 SoC in the ACLINT_SSWI
    interrupt chip
 
  - Make the interrupt routing to RISV-V harts specification compliant so it
    supports arbitrary hart indices
 
  - Add a command line parameter and related handling to disable the generic
    RISCV IMSIC mechanism on platforms which use a trap-emulated IMSIC.
    Unfortunatly this is required because there is no mechanism available to
    discover this programatically.
 
  - Enable wakeup sources on the Renesas RZV2H driver
 
  - Convert interrupt chip drivers, which use a open coded variant of
    msi_create_parent_irq_domain() to use the new functionality
 
  - Convert interrupt chip drivers, which use the old style two level
    implementation of MSI support over to the MSI parent mechanism to
    prepare for removing at least one of the three PCI/MSI backend variants.
 
  - The usual cleanups and improvements all over the place

dba3ec9f2a Updates for the interrupt core subsystem:
- Prevent a interrupt migration related live lock in handle_edge_irq()
 
     If the interrupt affinity is moved to a new target CPU and the
     interrupt is currently handled on the previous target CPU for edge type
     interrupts the handler might get stuck on the previous target for a
     long time, which causes both involved CPUs to waste cycles and
     eventually run into a soft-lockup situation.
 
     Solve this by checking whether the interrupt is redirected to a new
     target CPU and if the interrupt is handled on that new target CPU, busy
     wait for completion instead of masking it and sending the pending but
     which would cause the old CPU to re-run the handler and in the worst
     case repeating this excercise for a long time.
 
     This only works on architectures which use single CPU interrupt
     targets, but that's so far the only ones where this behaviour has been
     observed.
 
   - Add a kunit test for interrupt disable depth counts
 
     The nested interrupt disable depth has been an issue in the past
     especially vs. free_irq(), interrupt shutdown and CPU hotplug and their
     interactions. The test exercises the combinations of these scenarios
     and checks for correctness.

5e32d0f15c unwind_user/deferred: Add unwind_user_faultable()
Add a new API to retrieve a user space callstack called
unwind_user_faultable(). The difference between this user space stack
tracer from the current user space stack tracer is that this must be
called from faultable context as it may use routines to access user space
data that needs to be faulted in.

It can be safely called from entering or exiting a system call as the code
can still be faulted in there.

This code is based on work by Josh Poimboeuf's deferred unwinding code:

71753c6ed2 unwind_user: Add user space unwinding API with frame pointer support
Introduce a generic API for unwinding user stacks.

In order to expand user space unwinding to be able to handle more complex
scenarios, such as deferred unwinding and reading user space information,
create a generic interface that all architectures can use that support the
various unwinding methods.

This is an alternative method for handling user space stack traces from
the simple stack_trace_save_user() API. This does not replace that
interface, but this interface will be used to expand the functionality of
user space stack walking.

None of the structures introduced will be exposed to user space tooling.

Support for frame pointer unwinding is added. For an architecture to
support frame pointer unwinding it needs to enable
CONFIG_HAVE_UNWIND_USER_FP and define ARCH_INIT_USER_FP_FRAME.

By encoding the frame offsets in struct unwind_user_frame, much of this
code can also be reused for future unwinder implementations like sframe.

4df9c0a246 soc: new SoC support for 6.17
These five newly supported chips come with both devicetree descriptions
 and the changes to wire them up to the build system for easier bisection.
 
 The chips in question are:
 
  - Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
    in the product line that started with the Digital StrongARM SA1100
    based PDAs and continued with the Intel PXA2xx that dominated early
    smartphones. This one only made it only into a few products before the
    entire product line was cut in 2015.
 
  - The QiLai SoC is made by RISC-V core designer Andes Technologies
    and is in the 'Voyager' reference board in MicroATX form factor.
    It uses four in-order AX45MP cores, which is the midrange product
    from Andes.
 
  - CIX P1 is one of the few Arm chips designed for small workstations,
    and this one uses 12 Cortex-A720/A520 cores, making it also one
    of the only ARMv9.2 machines that one can but at the moment.
 
  - Axiado AX3000 is an embedded chip with relative small Cortex-A53
    CPU cores described as a "Trusted Control/Compute Unit" that can
    be used as a BMC in servers. In addition to the usual I/O, this one
    comes with 10GBit ethernet and and a 4TOPS NPU.
 
  - Sophgo SG2000 is an embedded chip that comes with both RISC-V
    and Arm cores that can run Linux. This was already supported for
    RISC-V but now it also works on Arm
 
 One more chip, the Black Sesame C1200 did not make it in tirm for the
 merge window.

0f46f50845 soc: driver updates for 6.17
Changes are all over the place, but very little sticks out as
 noteworthy.
 
 There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
 I/O chip, along with hooking it up to the pinctrl and clk frameworks.
 
 The reset controller and memory subsystems have mainly small updates,
 but there are two new reset drivers for the K230 and VC1800B SoCs,
 and new memory driver support for Tegra264.
 
 The ARM SMCCC and SCMI firmware drivers gain a few more features that
 should help them be supported across more environments. Similarly,
 the SoC specific firmware on Tegra and Qualcomm get minor enhancements
 and chip support.
 
 In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
 overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
 grow to support more chips, while the Hisilicon, Mediatek and Renesas
 drivers see mostly janitorial fixes.

115e74a29b soc: dt changes for 6.17
There are a few new variants of existing chips:
 
  - mt6572 is an older mobile phone chip from mediatek that was
    extremely popular a decade ago but never got upstreamed until now.
 
  - exynos2200 is a recent high-end mobile phone chip used in a
    few Samsung phones like the Galaxy S22
 
  - Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
    (R8A779H0) and used in automotive applications
 
  - Tegra264 is a new chip from NVIDIA, but support is fairly minimal
    for now, and not much information is public about it.
 
 There are five more chips in a separate branch, as those are new
 chip families that I merged along with the necessary infrastructure.
 
 New board support is not that exciting, with a total of 33 newly
 added machines here:
 
  - Evaluation platforms for the chips above, plus TI am62d2 and
    Sophgo sg2042.
 
  - Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
    plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
    imx95.
 
  - Two newly added ASPEED BMC based motherboards, and one that got
    removed
 
  - Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
    msm8976 SoCs
 
  - Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
 
  - A set-top box based on Amlogic meson-gxm.
 
 Updates for existing machines are spread over all the above families.
 One notable change here is support for the RP1 I/O chip used in
 Raspberry Pi 5.

 address of the FSF as the old one was incorrect and they finally no
 longer have that listed in the license files.  These updates come
 directly from the FSF copies of the files, so they mirror what they want

1641684528 Staging changes for 6.17-rc1
Here is the "big" set of staging driver changes for 6.17-rc1.  That's in
 quotes as it really isn't all that big of a set of changes this
 development cycle at all.
 
 Major things that stand out are:
   - gpib cleanups and tweaks with the majority of the big issues now
     taken care of.  Odds are it will move out of staging/ in the next
     merge window if all goes well.
   - more constant cleanups and layer removals from the rtl8723bs driver.
     It's amazing how many layers deep they really are, all cleanups here
     are great to see
   - axis-fifo sysfs api removed and debugfs api added.  The sysfs api
     didn't work at all so obviously no one was using it.  Add the same
     information into debugfs as that's the proper place for it, and make
     it actually work.
   - Remaining changes is lots of small checkpatch cleanups, most of
     which seem to have come from a Debconf session where people were
     encouraged to submit their first kernel patch, a nice thing to see
     happen again.
 
 All of these have been in linux-next with no reported issues.

Merge tag 'staging-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging updates from Greg KH:
 "Here is the "big" set of staging driver changes for 6.17-rc1. That's
  in quotes as it really isn't all that big of a set of changes this
  development cycle at all.

  Major things that stand out are:

   - gpib cleanups and tweaks with the majority of the big issues now
     taken care of. Odds are it will move out of staging/ in the next
     merge window if all goes well.

   - more constant cleanups and layer removals from the rtl8723bs
     driver. It's amazing how many layers deep they really are, all
     cleanups here are great to see

   - axis-fifo sysfs api removed and debugfs api added. The sysfs api
     didn't work at all so obviously no one was using it. Add the same
     information into debugfs as that's the proper place for it, and
     make it actually work.

   - Remaining changes is lots of small checkpatch cleanups, most of
     which seem to have come from a Debconf session where people were
     encouraged to submit their first kernel patch, a nice thing to see
     happen again.

  All of these have been in linux-next with no reported issues"

c2f9de5e2d PCI: Move is_pciehp check out of pciehp_is_native()
pci_bridge_d3_possible() seeks to forbid runtime power management on:

* Non Hot-Plug Capable PCIe ports which are nevertheless ACPI slots
  (recognizable as: bridge->is_hotplug_bridge && !bridge->is_pciehp)

* Hot-Plug Capable PCIe ports for which platform firmware has not granted
  PCIe Native Hot-Plug control to the operating system
  (recognizable as: bridge->is_pciehp && !pciehp_is_native(bridge))

Somewhat confusingly, the check for is_hotplug_bridge is in
pci_bridge_d3_possible(), whereas the one for is_pciehp is in
pciehp_is_native().

For clarity, check is_pciehp directly in pci_bridge_d3_possible()
(and in the other caller of pciehp_is_native(), hotplug_is_native()).

Rephrase the code comment preceding these checks to no longer mention
"System Management Mode", which is an x86 term inappropriate in generic
PCI code.  Likewise no longer mention "Thunderbolt on non-Macs", because
there is nothing Thunderbolt-specific about these checks.  It used to be
the case that non-Macs relied on the platform for Thunderbolt tunnel
management and hotplug, but they've since moved to OS-native tunnel
management (as Macs always have), hence the code comment is no longer
accurate.

There is a subsequent check for is_hotplug_bridge further down in
pci_bridge_d3_possible().  Change the check to is_pciehp because any
ports matching "bridge->is_hotplug_bridge && !bridge->is_pciehp" are
already filtered out at the top of the function.

Do the same for another check in acpi_pci_bridge_d3(), which is called
from pci_bridge_d3_possible() via platform_pci_bridge_d3().

No functional change intended.

c6036c3394 PCI: pciehp: Use is_pciehp instead of is_hotplug_bridge
The PCIe hotplug driver calculates the depth of a nested hotplug port by
looking at the is_hotplug_bridge flag.  The depth is used as lockdep class
to tell hotplug ports apart.

The is_hotplug_bridge flag encompasses ACPI slots handled by the ACPI
hotplug driver, hence the calculated depth may be too high.  Avoid by
checking the is_pciehp flag instead.

This glitch likely has no user-visible impact:  ACPI slots typically only
exist at the Root Port level, not in nested hotplug hierarchies.  Also,
CONFIG_LOCKDEP is usually only used by developers.  So this is just for
the sake of correctness.

1d60796a62 PCI/portdrv: Use is_pciehp instead of is_hotplug_bridge
The PCIe port driver erroneously creates a subdevice for hotplug on ACPI
slots which are handled by the ACPI hotplug driver.

Avoid by checking the is_pciehp flag instead of is_hotplug_bridge when
deciding whether to create a subdevice.  The latter encompasses ACPI slots
whereas the former doesn't.

The superfluous subdevice has no real negative impact, it occupies memory
and interrupt resources but otherwise just sits there waiting for
interrupts from the slot that are never signaled.

6cff20ce3b PCI/ACPI: Fix runtime PM ref imbalance on Hot-Plug Capable ports
pci_bridge_d3_possible() is called from both pcie_portdrv_probe() and
pcie_portdrv_remove() to determine whether runtime power management shall
be enabled (on probe) or disabled (on remove) on a PCIe port.

The underlying assumption is that pci_bridge_d3_possible() always returns
the same value, else a runtime PM reference imbalance would occur.  That
assumption is not given if the PCIe port is inaccessible on remove due to
hot-unplug:  pci_bridge_d3_possible() calls pciehp_is_native(), which
accesses Config Space to determine whether the port is Hot-Plug Capable.
An inaccessible port returns "all ones", which is converted to "all
zeroes" by pcie_capability_read_dword().  Hence the port no longer seems
Hot-Plug Capable on remove even though it was on probe.

The resulting runtime PM ref imbalance causes warning messages such as:

  pcieport 0000:02:04.0: Runtime PM usage count underflow!

Avoid the Config Space access (and thus the runtime PM ref imbalance) by
caching the Hot-Plug Capable bit in struct pci_dev.

The struct already contains an "is_hotplug_bridge" flag, which however is
not only set on Hot-Plug Capable PCIe ports, but also Conventional PCI
Hot-Plug bridges and ACPI slots.  The flag identifies bridges which are
allocated additional MMIO and bus number resources to allow for hierarchy
expansion.

The kernel is somewhat sloppily using "is_hotplug_bridge" in a number of
places to identify Hot-Plug Capable PCIe ports, even though the flag
encompasses other devices.  Subsequent commits replace these occurrences
with the new flag to clearly delineate Hot-Plug Capable PCIe ports from
other kinds of hotplug bridges.

Document the existing "is_hotplug_bridge" and the new "is_pciehp" flag
and document the (non-obvious) requirement that pci_bridge_d3_possible()
always returns the same value across the entire lifetime of a bridge,
including its hot-removal.
