Pull gpio fixes from Bartosz Golaszewski:
 "Apart from some regular driver fixes there's a relatively big revert
  of the locking changes that were introduced to GPIOLIB in this merge
  window.

  This is because it turned out that some legacy GPIO interfaces - that
  need to translate a number from the global GPIO numberspace to the
  address of the relevant descriptor, thus running a GPIO device lookup
  and taking the GPIO device list lock - are still used in old code from
  atomic context resulting in "scheduling while atomic" errors.

  I'll try to make the read-only part of the list access entirely
  lockless using SRCU but this will take some time so let's go back to
  the old global spinlock for now.

  Summary:

   - revert the changes aiming to use a read-write semaphore to protect
     the list of GPIO devices due to calls to legacy API taking that
     lock from atomic context in old code

   - fix inverted logic in DEFINE_FREE() for GPIO device references

   - check the return value of bgpio_init() in gpio-mlxbf3

Pull pwm fixes from Uwe Kleine-König:

 - fix a duplicate cleanup in an error path introduced in
   this merge window

 - fix an out-of-bounds access

   In practise it doesn't happen - otherwise someone would have noticed
   since v5.17-rc1 I guess - because the device tree binding for the two
   drivers using of_pwm_single_xlate() only have args->args_count == 1.

   A device-tree that doesn't conform to the respective bindings could
   trigger that easily however.

 - correct the request callback of the jz4740 pwm driver which used
   dev_err_probe() long after .probe() completed.

   This is conceptually wrong because dev_err_probe() might call
   device_set_deferred_probe_reason() which is nonsensical after the
   driver is bound.

Pull CXL (Compute Express Link) updates from Dan Williams:
 "The bulk of this update is support for enumerating the performance
  capabilities of CXL memory targets and connecting that to a platform
  CXL memory QoS class. Some follow-on work remains to hook up this data
  into core-mm policy, but that is saved for v6.9.

  The next significant update is unifying how CXL event records (things
  like background scrub errors) are processed between so called
  "firmware first" and native error record retrieval. The CXL driver
  handler that processes the record retrieved from the device mailbox is
  now the handler for that same record format coming from an EFI/ACPI
  notification source.

  This also contains miscellaneous feature updates, like Get Timestamp,
  and other fixups.

Pull eventfs updates from Steven Rostedt:

 - Remove "lookup" parameter of create_dir_dentry() and
   create_file_dentry(). These functions were called by lookup and the
   readdir logic, where readdir needed it to up the ref count of the
   dentry but the lookup did not. A "lookup" parameter was passed in to
   tell it what to do, but this complicated the code. It is better to
   just always up the ref count and require the caller to decrement it,
   even for lookup.

 - Modify the .iterate_shared callback to not use the dcache_readdir()
   logic and just handle what gets displayed by that one function. This
   removes the need for eventfs to hijack the file->private_data from
   the dcache_readdir() "cursor" pointer, and makes the code a bit more
   sane

 - Use the root and instance inodes for default ownership. Instead of
   walking the dentry tree and updating each dentry gid, use the
   getattr(), setattr() and permission() callbacks to set the ownership
   and permissions using the root or instance as the default

 - Some other optimizations with the eventfs iterate_shared logic

 - Hard-code the inodes for eventfs to the same number for files, and
   the same number for directories

 - Have getdent() not create dentries/inodes in iterate_shared() as now
   it has hard-coded inode numbers

 - Use kcalloc() instead of kzalloc() on a list of elements

 - Fix seq_buf warning and make static work properly.

Pull tracing updates from Steven Rostedt:

 - Allow kernel trace instance creation to specify what events are
   created

   Inside the kernel, a subsystem may create a tracing instance that it
   can use to send events to user space. This sub-system may not care
   about the thousands of events that exist in eventfs. Allow the
   sub-system to specify what sub-systems of events it cares about, and
   only those events are exposed to this instance.

 - Allow the ring buffer to be broken up into bigger sub-buffers than
   just the architecture page size.

   A new tracefs file called "buffer_subbuf_size_kb" is created. The
   user can now specify a minimum size the sub-buffer may be in
   kilobytes. Note, that the implementation currently make the
   sub-buffer size a power of 2 pages (1, 2, 4, 8, 16, ...) but the user
   only writes in kilobyte size, and the sub-buffer will be updated to
   the next size that it will can accommodate it. If the user writes in
   10, it will change the size to be 4 pages on x86 (16K), as that is
   the next available size that can hold 10K pages.

 - Update the debug output when a corrupt time is detected in the ring
   buffer. If the ring buffer detects inconsistent timestamps, there's a
   debug config options that will dump the contents of the meta data of
   the sub-buffer that is used for debugging. Add some more information
   to this dump that helps with debugging.

 - Add more timestamp debugging checks (only triggers when the config is
   enabled)

 - Increase the trace_seq iterator to 2 page sizes.

 - Allow strings written into tracefs_marker to be larger. Up to just
   under 2 page sizes (based on what trace_seq can hold).

 - Increase the trace_maker_raw write to be as big as a sub-buffer can
   hold.

 - Remove 32 bit time stamp logic, now that the rb_time_cmpxchg() has
   been removed.

 - More selftests were added.

 - Some code clean ups as well.

Pull probes update from Masami Hiramatsu:

 - Update the Kprobes trace event to show the actual function name in
   notrace-symbol warning.

   Instead of using the user specified symbol name, use "%ps" printk
   format to show the actual symbol at the probe address. Since kprobe
   event accepts the offset from symbol which is bigger than the symbol
   size, the user specified symbol may not be the actual probed symbol.

Pull x86 TDX updates from Dave Hansen:
 "This contains the initial support for host-side TDX support so that
  KVM can run TDX-protected guests. This does not include the actual
  KVM-side support which will come from the KVM folks. The TDX host
  interactions with kexec also needs to be ironed out before this is
  ready for prime time, so this code is currently Kconfig'd off when
  kexec is on.

  The majority of the code here is the kernel telling the TDX module
  which memory to protect and handing some additional memory over to it
  to use to store TDX module metadata. That sounds pretty simple, but
  the TDX architecture is rather flexible and it takes quite a bit of
  back-and-forth to say, "just protect all memory, please."

  There is also some code tacked on near the end of the series to handle
  a hardware erratum. The erratum can make software bugs such as a
  kernel write to TDX-protected memory cause a machine check and
  masquerade as a real hardware failure. The erratum handling watches
  out for these and tries to provide nicer user errors"

Using the address operator on the array doesn't work:

./include/linux/seq_buf.h:27:27: error: initialization of ‘char *’
  from incompatible pointer type ‘char (*)[128]’
  [-Werror=incompatible-pointer-types]

      |                           ^

Apart from fixing that, we can improve DECLARE_SEQ_BUF() by using a
compound literal to define the buffer array without attaching a name
to it. This makes the macro a single statement, allowing constructs
such as:

  static DECLARE_SEQ_BUF(my_seq_buf, MYSB_SIZE);

to work as intended.

 "Enumeration:

   - Reserve ECAM so we don't assign it to PCI BARs; this works around
     bugs where BIOS included ECAM in a PNP0A03 host bridge window,
     didn't reserve it via a PNP0C02 motherboard device, and didn't
     allocate space for SR-IOV VF BARs (Bjorn Helgaas)

   - Add MMCONFIG/ECAM debug logging (Bjorn Helgaas)

   - Rename 'MMCONFIG' to 'ECAM' to match spec usage (Bjorn Helgaas)

   - Log device type (Root Port, Switch Port, etc) during enumeration
     (Bjorn Helgaas)

   - Log bridges before downstream devices so the dmesg order is more
     logical (Bjorn Helgaas)

   - Log resource names (BAR 0, VF BAR 0, bridge window, etc)
     consistently instead of a mix of names and "reg 0x10" (Puranjay
     Mohan, Bjorn Helgaas)

   - Fix 64GT/s effective data rate calculation to use 1b/1b encoding
     rather than the 8b/10b or 128b/130b used by lower rates (Ilpo

     lpfc (Ilpo Järvinen)

   - Clean up open-coded PCIBIOS return code mangling (Ilpo Järvinen)

  Resource management:

   - Restructure pci_dev_for_each_resource() to avoid computing the
     address of an out-of-bounds array element (the bounds check was
     performed later so the element was never actually *read*, but it's
     nicer to avoid even computing an out-of-bounds address) (Andy
     Shevchenko)

  Driver binding:

   - Convert pci-host-common.c platform .remove() callback to
     .remove_new() returning 'void' since it's not useful to return
     error codes here (Uwe Kleine-König)

   - Convert exynos, keystone, kirin from .remove() to .remove_new(),

   - Drop unused struct pci_driver.node member (Mathias Krause)

  Virtualization:

   - Add ACS quirk for more Zhaoxin Root Ports (LeoLiuoc)

  MediaTek PCIe controller driver:

   - Clear MSI interrupt status before handler to avoid missing MSIs
     that occur after the handler (qizhong cheng)

  MediaTek PCIe Gen3 controller driver:

   - Update mediatek-gen3 translation window setup to handle MMIO space
     that is not a power of two in size (Jianjun Wang)

  Qualcomm PCIe controller driver:

     regulators on KingFisher (Wolfram Sang)

   - Align iATU mapping for endpoint MSI-X (Niklas Cassel)

   - Add Endpoint DBI accessors to encapsulate offset lookups (Yoshihiro
     Shimoda)

   - Add j721e DT compatible strings and driver support for j784s4 (Matt
     Ranostay)

   - Make TI J721E Kconfig depend on ARCH_K3 since the hardware is

  TI Keystone PCIe controller driver:

   - Hold power management references to all PHYs while enabling them to
     avoid a race when one provides clocks to others (Siddharth
     Vadapalli)

  Xilinx XDMA PCIe controller driver:

   - Remove redundant dev_err(), since platform_get_irq() and
     platform_get_irq_byname() already log errors (Yang Li)

   - Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq()
     (Krzysztof Wilczyński)

   - Fix xilinx_pl_dma_pcie_init_irq_domain() error return when
     irq_domain_add_linear() fails (Harshit Mogalapalli)

  MicroSemi Switchtec management driver:

   - Do dma_mrpc cleanup during switchtec_pci_remove() to match its devm
     ioremapping in switchtec_pci_probe(). Previously the cleanup was
     done in stdev_release(), which used stale pointers if stdev->cdev
     happened to be open when the PCI device was removed (Daniel
     Stodden)

  Miscellaneous:

   - Convert interrupt terminology from "legacy" to "INTx" to be more
     specific and match spec terminology (Damien Le Moal)

   - In dw-xdata-pcie, pci_endpoint_test, and vmd, replace usage of
     deprecated ida_simple_*() API with ida_alloc() and ida_free()
     (Christophe JAILLET)"

The NCT3015Y-R and NCT3018Y-R use the same datasheet
    but have different topologies as follows.
- Topology (Only 1st i2c can set TWO bit and HF bit)
  In NCT3015Y-R,
    rtc 1st i2c is connected to a host CPU
    rtc 2nd i2c is connected to a BMC
  In NCT3018Y-R,
    rtc 1st i2c is connected to a BMC
    rtc 2nd i2c is connected to a host CPU
In order to be compatible with NCT3015Y-R and NCT3018Y-R,
- In probe,
  If part number is NCT3018Y-R, only set HF bit to 24-Hour format.
  Else, do nothing
- In set_time,
  If part number is NCT3018Y-R && TWO bit is 0,
     change TWO bit to 1, and restore TWO bit after updating time.

Pull pin control updates from Linus Walleij:
 "For this kernel cycle I managed an immutable branch for the PEF2256
  WAN framer that has some pin control portions. It already landed in
  your tree through the net pull request but here it is mentioned again.

  The most interesting is perhaps the Samsung Exynos subdrivers for the
  Tensor SoC used in Google Pixel 6 and the ExynosAuto subdriver for
  automotive. Along with the earlier merged Tesla FSD subdriver it shows
  some of the versatile uses of the Samsung Exynos silicon. It is also
  used in the latest version of Axis Communications ARTPEC chips so it
  is a very widely deployed SoC family.

  We also have the Intel Meteor Lake SoC which I think is for laptops.
  It's a pretty interesting chip with Xe graphics and integrated PCH.

  Core changes:

   - A new PINCTRL_GROUP_DESC() infrastructure macro is added and used
     in different drivers, generic group description struct group_desc
     is now used all over the place.

  New drivers:

   - New driver for the Texas Instruments TPS6494 Power Management IC.

   - New driver for the Lantic PEF2256 framer pin multiplexer. This IC
     has some pins that can be reconfigured in different ways. The
     actual driver comes on an immutable branch with the net WAN parts,
     the IC is some latest-and-greatest serial line funnel for e.g.
     wireless access points.

   - New subdriver for the Samsung Exynos Auto V920 pin controller, used
     for automotive applications.

   - New subdriver for the Samsung "GS101" SoC pin controller, this is
     the Google "Tensor" SoC used in the Google Pixel 6.

   - New subdriver for the Intel Meteor Point SoC pin controller.

   - New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS
     pin controllers.

   - New subdriver for the Qualcomm X1E80100 top level (TLMM) pin
     controller.

   - New subdriver for the Qualcomm SM4450 top level (TLMM) pin
     controller.

   - The "single" pin controller now supports the Texas Instruments
     J7200 SoC.

  Improvements:

   - Intel has created a new (Intel-)generic pin controller driver that
     is now used by all contemporary Intel platforms.

   - Intel is now also making use of some cleanup helpers.

   - Enble 910 Ohm bias in the Intel Tangier driver.

   - The Samsung driver now suppors irq_set_affinity() in it's IRQ chip
     giving support for non wake up external gpio interrupts"
