7f15ee3597 dpll: add reference-sync netlink attribute
Add new netlink attribute to allow user space configuration of reference
sync pin pairs, where both pins are used to provide one clock signal
consisting of both: base frequency and sync signal.

c035e73603 dpll: add phase-offset-monitor feature to netlink spec
Add enum dpll_feature_state for control over features.

Add dpll device level attribute:
DPLL_A_PHASE_OFFSET_MONITOR - to allow control over a phase offset monitor
feature. Attribute is present and shall return current state of a feature
(enum dpll_feature_state), if the device driver provides such capability,
otherwie attribute shall not be present.

 constant forward progress of new device support and cleanups to existing
 subsystems.  Highlights in here are:
   - Large IIO driver updates and additions and device tree changes
   - Android binder bugfixes and logfile fixes
   - mhi driver updates
   - comedi driver updates
   - counter driver updates and additions
   - coresight driver updates and additions
   - echo driver removal as there are no in-kernel users of it
   - nvmem driver updates
   - spmi driver updates
   - new amd-sbi driver "subsystem" and drivers added
   - rust miscdriver binding documentation fix

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Print the actual delay time in pci_bridge_wait_for_secondary_bus()
     instead of assuming it was 1000ms (Wilfred Mallawa)

   - Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
     devices', which broke resume from system sleep on AMD platforms and
     has been fixed by other commits (Lukas Wunner)

  Resource management:

   - Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
     and unnecessary (Philipp Stanner)

   - Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
     and related flags since all uses have been removed (Philipp
     Stanner)

   - Rework devres 'request' functions so they are no longer 'hybrid',
     i.e., their behavior no longer depends on whether
     pcim_enable_device or pci_enable_device() was used, and remove
     related code (Philipp Stanner)

   - Warn (not BUG()) about failure to assign optional resources (Ilpo
     Järvinen)

  Error handling:

   - Log the DPC Error Source ID only when it's actually valid (when
     ERR_FATAL or ERR_NONFATAL was received from a downstream device)
     and decode into bus/device/function (Bjorn Helgaas)

   - Determine AER log level once and save it so all related messages
     use the same level (Karolina Stolarek)

   - Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
     Errors (Karolina Stolarek)

   - Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
     controls on interval and burst count, to avoid flooding logs and
     RCU stall warnings (Jon Pan-Doh)

  Power management:

   - Increment PM usage counter when probing reset methods so we don't
     try to read config space of a powered-off device (Alex Williamson)

   - Set all devices to D0 during enumeration to ensure ACPI opregion is
     connected via _REG (Mario Limonciello)

  Power control:

   - Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
     the filename paths. Retain old deprecated symbols for
     compatibility, except for the pwrctrl slot driver
     (PCI_PWRCTRL_SLOT) (Johan Hovold)

   - When unregistering pwrctrl, cancel outstanding rescan work before
     cleaning up data structures to avoid use-after-free issues (Brian
     Norris)

  Bandwidth control:

   - Simplify link bandwidth controller by replacing the count of Link
     Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
     flag (Ilpo Järvinen)

   - Update the Link Speed after retraining, since the Link Speed may
     have changed (Ilpo Järvinen)

  PCIe native device hotplug:

   - Ignore Presence Detect Changed caused by DPC.

     pciehp already ignores Link Down/Up events caused by DPC, but on
     slots using in-band presence detect, DPC causes a spurious Presence
     Detect Changed event (Lukas Wunner)

   - Ignore Link Down/Up caused by Secondary Bus Reset.

     On hotplug ports using in-band presence detect, the reset causes a
     Presence Detect Changed event, which mistakenly caused teardown and
     re-enumeration of the device. Drivers may need to annotate code
     that resets their device (Lukas Wunner)

  Virtualization:

   - Add an ACS quirk for Loongson Root Ports that don't advertise ACS
     but don't allow peer-to-peer transactions between Root Ports; the
     quirk allows each Root Port to be in a separate IOMMU group (Huacai
     Chen)

  Endpoint framework:

   - For fixed-size BARs, retain both the actual size and the possibly
     larger size allocated to accommodate iATU alignment requirements
     (Jerome Brunet)

   - Simplify ctrl/SPAD space allocation and avoid allocating more space
     than needed (Jerome Brunet)

   - Correct MSI-X PBA offset calculations for DesignWare and Cadence
     endpoint controllers (Niklas Cassel)

   - Align the return value (number of interrupts) encoding for
     pci_epc_get_msi()/pci_epc_ops::get_msi() and
     pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)

   - Align the nr_irqs parameter encoding for
     pci_epc_set_msi()/pci_epc_ops::set_msi() and
     pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)

  Common host controller library:

   - Convert pci-host-common to a library so platforms that don't need
     native host controller drivers don't need to include these helper
     functions (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Extract ECAM bridge creation helper from pci_host_common_probe() to
     separate driver-specific things like MSI from PCI things (Marc
     Zyngier)

   - Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
     varying capabilities (Marc Zyngier)

   - Skip ports disabled in DT when setting up ports (Janne Grunau)

   - Add t6020 compatible string (Alyssa Rosenzweig)

   - Add T602x PCIe support (Hector Martin)

   - Directly set/clear INTx mask bits because T602x dropped the
     accessors that could do this without locking (Marc Zyngier)

   - Move port PHY registers to their own reg items to accommodate
     T602x, which moves them around; retain default offsets for existing
     DTs that lack phy%d entries with the reg offsets (Hector Martin)

   - Stop polling for core refclk, which doesn't work on T602x and the
     bootloader has already done anyway (Hector Martin)

   - Use gpiod_set_value_cansleep() when asserting PERST# in probe
     because we're allowed to sleep there (Hector Martin)

  Cadence PCIe controller driver:

   - Drop a runtime PM 'put' to resolve a runtime atomic count underflow
     (Hans Zhang)

   - Make the cadence core buildable as a module (Kishon Vijay Abraham I)

   - Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
     loadable drivers when they are removed (Siddharth Vadapalli)

  Freescale i.MX6 PCIe controller driver:

   - Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
     (Richard Zhu)

   - Remove redundant dw_pcie_wait_for_link() from
     imx_pcie_start_link(); since the DWC core does this, imx6 only
     needs it when retraining for a faster link speed (Richard Zhu)

   - Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)

   - Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
     some cases, the controller can't exit 'L23 Ready' through Beacon or
     PERST# deassertion (Richard Zhu)

   - Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
     controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
     GT/s, causing timeouts in L1 (Richard Zhu)

   - Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)

   - Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

  Mobiveil PCIe controller driver:

   - Return bool (not int) for link-up check in
     mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
     Zhang)

  NVIDIA Tegra194 PCIe controller driver:

   - Create debugfs directory for 'aspm_state_cnt' only when
     CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
     Zhang)

  Qualcomm PCIe controller driver:

   - Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
     equalization presets (Krishna Chaitanya Chundru)

   - Read Maximum Link Width from the Link Capabilities register if DT
     lacks 'num-lanes' property (Krishna Chaitanya Chundru)

   - Add Physical Layer 64 GT/s Capability ID and register offsets for
     8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
     Chundru)

   - Add generic dwc support for configuring lane equalization presets
     (Krishna Chaitanya Chundru)

   - Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)

  Renesas R-Car PCIe controller driver:

   - Describe endpoint BAR 4 as being fixed size (Jerome Brunet)

   - Document how to obtain R-Car V4H (r8a779g0) controller firmware
     (Yoshihiro Shimoda)

  Rockchip PCIe controller driver:

   - Reorder rockchip_pci_core_rsts because
     reset_control_bulk_deassert() deasserts in reverse order, to fix a
     link training regression (Jensen Huang)

   - Mark RK3399 as being capable of raising INTx interrupts (Niklas
     Cassel)

  Rockchip DesignWare PCIe controller driver:

   - Check only PCIE_LINKUP, not LTSSM status, to determine whether the
     link is up (Shawn Lin)

   - Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
     for Root Complex and Endpoint modes (Shawn Lin)

   - Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
     of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
     resets non-sticky registers (Shawn Lin)

   - Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
     (Diederik de Haas)

  Synopsys DesignWare PCIe controller driver:

   - Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
     more robust; this will not affect the intended link width if all
     lanes are functional (Wenbin Yao)

   - Return bool (not int) for link-up check in dw_pcie_ops.link_up()
     and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
     keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
     tegra194, uniphier, visconti (Hans Zhang)

   - Add debugfs support for exposing DWC device-specific PTM context
     (Manivannan Sadhasivam)

  TI J721E PCIe driver:

   - Make j721e buildable as a loadable and removable module (Siddharth
     Vadapalli)

   - Fix j721e host/endpoint dependencies that result in link failures
     in some configs (Arnd Bergmann)

  Device tree bindings:

   - Add qcom DT binding for 'global' interrupt (PCIe controller and
     link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
     sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan
     Sadhasivam)

   - Add dw rockchip DT binding for rk3576 and rk3562 (Kever Yang)

   - Correct indentation and style of examples in brcm,stb-pcie,
     cdns,cdns-pcie-ep, intel,keembay-pcie-ep, intel,keembay-pcie,
     microchip,pcie-host, rcar-pci-ep, rcar-pci-host, xilinx-versal-cpm
     (Krzysztof Kozlowski)

   - Convert Marvell EBU (dove, kirkwood, armada-370, armada-xp) and
     armada8k from text to schema DT bindings (Rob Herring)

   - Remove obsolete .txt DT bindings for content that has been moved to
     schemas (Rob Herring)

   - Add qcom DT binding for MHI registers in IPQ5332, IPQ6018, IPQ8074

  Miscellaneous:

   - Drop 'pci' suffix from intel_mid_pci.c filename to match similar
     files (Andy Shevchenko)

   - All platforms with PCI have an MMU, so add PCI Kconfig dependency

02897f5e56 Restructure the IPMI driver for 6.16
This is a restructure of the IPMI driver, mostly to remove SRCU.  The
 locking had issues, and they were not going to be straightforward to
 fix.  Plus it used tons of memory and was generally a pain.
 
 Most of this moves handling of messages out of bh and interrupt context
 and runs it in thread context.  Then getting rid of SRCU is easy.
 
 This also has a minor cleanup to remove a warning on newer GCCs and to
 fix some documentation.

GPIO core:
 - use more lock guards where applicable
 - refactor GPIO ACPI code and shrink it in the process by 8%
 - move GPIO ACPI quirks into a separate file
 - remove unneeded #ifdef
 - convert GPIO devres helpers to using devm_add_action() where applicable
   which shrinks and simplifies the code
 - refactor GPIO descriptor validation in GPIO consumer interfaces
 - don't allow setting values on input lines in the GPIO core which will
   take off the burden from GPIO drivers of checking this down the line
 - provide gpiod_is_equal() as a way of safely comparing two GPIO
   descriptors (the only current user is in regulator core)
 
 New drivers:
 - add the GPIO module for the max77759 multifunction device
 - add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
 - add the GPIO driver for the Spacemit K1 SoC
 
 Driver improvements:
 - convert more drivers to using the new GPIO line value setter callbacks
 - convert more drivers to making the irq_chip immutable as is recommended
   by the interrupt subsystem
 - extend build testing coverage by enabling more modules to be built with
   COMPILE_TEST=y
 - extend the gpio-aggregator module with a configfs interface that makes
   the setup easier for user-space than the existing driver-level sysfs
   attributes and also adds more advanced configuration features (such as
   referring to aggregated lines by their original names or modifying
   their names as exposed by the aggregated chip)
 - add a missing mutex_destroy() in gpio-imx-scu
 - add an OF polarity quirk for s5m8767
 - allow building gpio-vf610 as a loadable module
 - make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS

 - add support for level-triggered interrupts to gpio-pca953x
 - don't double-check the ngpios property in gpio-ds4520 as GPIO core
   already does it
 - don't double-check the number of GPIOs in gpio-imx-scu as GPIO core

 "We have three new drivers, some refactoring in the GPIO core, lots of
  various changes across many drivers, new configfs interface for the
  virtual gpio-aggregator module and DT-bindings updates.

  The treewide conversion of GPIO drivers to using the new value setter
  callbacks is ongoing with another round of GPIO drivers updated. You
  will also see these commits coming in from other subsystems as with
  the relevant changes merged into mainline last cycle, I've started
  converting GPIO providers located elsewhere than drivers/gpio/.

3e443d1673 A moderately busy cycle for documentation this time around:

   script (a monstrous collection of Perl regexes that predates the Git era)
   with a Python reimplementation.  That, too, is a horrifying collection of
   regexes, but in a much cleaner and more maintainable structure that
   integrates far better with the Sphinx build system.
 
   This change has been in linux-next for the full 6.15 cycle; the small
   number of problems that turned up have been addressed, seemingly to
   everybody's satisfaction.  The Perl kernel-doc script remains in tree (as
   scripts/kernel-doc.pl) and can be used with a command-line option if need
   be.  Unless some reason to keep it around materializes, it will probably
   go away in 6.17.

01465f296a nvmem: Remove unused nvmem cell table support
Board files are deprecated by DT, and the last user of
nvmem_add_cell_table() was removed by commit 2af4fcc0d3 ("ARM:
davinci: remove unused board support") in v6.3.  Hence remove all
support for nvmem cell tables, and update the documentation.

Device drivers can still register a single cell using
nvmem_add_one_cell() (which was not documented before).

b9e22b35d4 tsm-mr: Add TVM Measurement Register support
Introduce new TSM Measurement helper library (tsm-mr) for TVM guest drivers
to expose MRs (Measurement Registers) as sysfs attributes, with Crypto
Agility support.

Add the following new APIs (see include/linux/tsm-mr.h for details):

- tsm_mr_create_attribute_group(): Take on input a `struct
  tsm_measurements` instance, which includes one `struct
  tsm_measurement_register` per MR with properties like `TSM_MR_F_READABLE`
  and `TSM_MR_F_WRITABLE`, to determine the supported operations and create
  the sysfs attributes accordingly. On success, return a `struct
  attribute_group` instance that will typically be included by the guest
  driver into `miscdevice.groups` before calling misc_register().

- tsm_mr_free_attribute_group(): Free the memory allocated to the attrubute
  group returned by tsm_mr_create_attribute_group().

tsm_mr_create_attribute_group() creates one attribute for each MR, with
names following this pattern:

        MRNAME[:HASH]

- MRNAME - Placeholder for the MR name, as specified by
  `tsm_measurement_register.mr_name`.
- :HASH - Optional suffix indicating the hash algorithm associated with
  this MR, as specified by `tsm_measurement_register.mr_hash`.

Support Crypto Agility by allowing multiple definitions of the same MR
(i.e., with the same `mr_name`) with distinct HASH algorithms.

NOTE: Crypto Agility, introduced in TPM 2.0, allows new hash algorithms to
be introduced without breaking compatibility with applications using older
algorithms. CC architectures may face the same challenge in the future,
needing new hashes for security while retaining compatibility with older
hashes, hence the need for Crypto Agility.

Duplicate C declaration, also defined at driver-api/usb/gadget:804
There is a function usb_string in the file message.c,
there is also a struct usb_string in the kernel api headers.
The docs is unable to index the function as the index is occupied by struct
This fix adds messgae.c to the usb_core namespace (in docs) hence providing
usb_sting a unique index usb_core.usb_string()

docs: initramfs: update compression and mtime descriptions
Update the document to reflect that initramfs didn't replace initrd
following kernel 2.5.x.
The initramfs buffer format now supports many compression types in
addition to gzip, so include them in the grammar section.
c_mtime use is dependent on CONFIG_INITRAMFS_PRESERVE_MTIME.
