014619ac2c media: dt-bindings: nxp,imx8-isi: Add i.MX91 ISI compatible string
The ISI module on i.MX91 is reused from i.MX93 and implements one channel
and one camera input which only can be connected to parallel camera input.
So needn't to select camera source like i.MX93 in gasket ops.

Linus Torvalds
522ba450b5 There's a bunch of patches here across drivers/clk/ to migrate drivers to use
struct clk_ops::determine_rate() instead of the round_rate() one so that we can
 remove the round_rate clk_op entirely. Brian has taken up that task which
 nobody else has wanted to do for close to a decade. Thanks Brian! This is all
 prerequisite work to get to the real task of improving the clk rate setting
 process. Once we have determine_rate() used everywhere, we'll be able to do
 things like chain the rate request structs in linked lists to order the rate
 setting operations or add more parameters without having to change every clk
 driver in existence. It's also nice to not have multiple ways to do something
 which just causes confusion for clk driver authors. Overall I'm glad this is
 getting done.
 
 Beyond this change we also have a tweak to the clk_lookup() function in the
 core framework to use hashing on the clk name instead of a clk tree walk with
 string comparisons. We _still_ rely on the clk name to be unique, because
 historically we've used globally unique strings to describe the clk tree
 topology. This tree walk becomes increasingly slow as more clks are added to
 the system. Searching from the roots for a duplicate is simple but pretty dumb
 and it wastes boot time so we're using a hash table as an improvement. Ideally
 we wouldn't rely on the strings to be unique at all, relegating them to simply
 debug information, but that is future work that will likely require some sort
 of Kconfig knob indicating strings aren't used for topology description.
 
 Outside of the core framework changes we have the usual new SoC support and
 fixes to clk drivers for things that were discovered once the clks were used by
 consumer drivers. Nothing in particular is jumping out at me in the "misc"
 pile, except maybe the Amlogic driver that has gone through a refactoring. That
 series got a fix from testing in -next though so it seems likely that things
 have been getting good test coverage for a couple weeks already.

The MediaTek MT8196 SoC includes an embedded MCU referred to as "GPUEB",
acting as glue logic to control power and frequency of the Mali GPU.
This MCU runs special-purpose firmware for this use, and the main
application processor communicates with it through a mailbox.

Add a binding that describes this mailbox.

Merge tag 'pci-v6.18-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
     take config space accessor functions.

     Implement pci_find_capability(), pci_find_ext_capability(), and
     dwc, dwc endpoint, and cadence capability search interfaces with
     them (Hans Zhang)

   - Leave parent unit address 0 in 'interrupt-map' so that when we
     build devicetree nodes to describe PCI functions that contain
     multiple peripherals, we can build this property even when
     interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)

   - Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
     Request Size to 128B to avoid a performance issue (Ilpo Järvinen)

   - Add sysfs 'serial_number' file to expose the Device Serial Number
     (Matthew Wood)

   - Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)

  Resource management:

   - Align m68k pcibios_enable_device() with other arches (Ilpo
     Järvinen)

   - Remove sparc pcibios_enable_device() implementations that don't do
     anything beyond what pci_enable_resources() does (Ilpo Järvinen)

   - Remove mips pcibios_enable_resources() and use
     pci_enable_resources() instead (Ilpo Järvinen)

   - Clean up bridge window sizing and assignment (Ilpo Järvinen),
     including:

       - Leave non-claimed bridge windows disabled

       - Enable bridges even if a window wasn't assigned because not all
         windows are required by downstream devices

       - Preserve bridge window type when releasing the resource, since
         the type is needed for reassignment

       - Consolidate selection of bridge windows into two new
         interfaces, pbus_select_window() and
         pbus_select_window_for_type(), so this is done consistently

       - Compute bridge window start and end earlier to avoid logging
         stale information

  MSI:

   - Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
     Vives)

  Error handling:

   - Align AER with EEH by allowing drivers to request a Bus Reset on
     Non-Fatal Errors (in addition to the reset on Fatal Errors that we
     already do) (Lukas Wunner)

   - If error recovery fails, emit FAILED_RECOVERY uevents for the
     devices, not for the bridge leading to them.

     This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)

   - Align AER with EEH by calling err_handler.error_detected()
     callbacks to notify drivers if error recovery fails (Lukas Wunner)

   - Align AER with EEH by restoring device error_state to
     pci_channel_io_normal before the err_handler.slot_reset() callback.

     This is earlier than before the err_handler.resume() callback
     (Lukas Wunner)

   - Emit a BEGIN_RECOVERY uevent when driver's
     err_handler.error_detected() requests a reset, as well as when it
     says recovery is complete or can be done without a reset (Niklas
     Schnelle)

   - Align s390 with AER and EEH by emitting uevents during error
     recovery (Niklas Schnelle)

   - Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
     SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
     result of err_handler.error_detected() (Niklas Schnelle)

   - Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
     error information identifies a device without an AER Capability
     (Breno Leitao)

   - Update error decoding and TLP Log printing for new errors in
     current PCIe base spec (Lukas Wunner)

   - Update error recovery documentation to match the current code
     and use consistent nomenclature (Lukas Wunner)

  ASPM:

   - Enable all ClockPM and ASPM states for devicetree platforms, since
     there's typically no firmware that enables ASPM

     This is a risky change that may uncover hardware or configuration
     defects at boot-time rather than when users enable ASPM via sysfs
     later. Booting with "pcie_aspm=off" prevents this enabling
     (Manivannan Sadhasivam)

   - Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)

  Power management:

   - If a device has already been disconnected, e.g., by a hotplug
     removal, don't bother trying to resume it to D0 when detaching the
     driver.

     This avoids annoying "Unable to change power state from D3cold to
     D0" messages (Mario Limonciello)

   - Ensure devices are powered up before config reads for
     'max_link_width', 'current_link_speed', 'current_link_width',
     'secondary_bus_number', and 'subordinate_bus_number' sysfs files.

     This prevents using invalid data (~0) in drivers or lspci and,
     depending on how the PCIe controller reports errors, may avoid
     error interrupts or crashes (Brian Norris)

  Virtualization:

   - Add rescan/remove locking when enabling/disabling SR-IOV, which
     avoids list corruption on s390, where disabling SR-IOV also
     generates hotplug events (Niklas Schnelle)

  Peer-to-peer DMA:

   - Free struct p2p_pgmap, not a member within it, in the
     pci_p2pdma_add_resource() error path (Sungho Kim)

  Endpoint framework:

   - Document sysfs interface for BAR assignment of vNTB endpoint
     functions (Jerome Brunet)

   - Fix array underflow in endpoint BAR test case (Dan Carpenter)

   - Skip endpoint IRQ test if the IRQ is out of range to avoid false
     errors (Christian Bruel)

   - Fix endpoint test case for controllers with fixed-size BARs smaller
     than requested by the test (Marek Vasut)

   - Restore inbound translation when disabling doorbell so the endpoint
     doorbell test case can be run more than once (Niklas Cassel)

   - Avoid a NULL pointer dereference when releasing DMA channels in
     endpoint DMA test case (Shin'ichiro Kawasaki)

   - Convert tegra194 interrupt number to MSI vector to fix endpoint
     Kselftest MSI_TEST test case (Niklas Cassel)

   - Reset tegra194 BARs when running in endpoint mode so the BAR tests
     don't overwrite the ATU settings in BAR4 (Niklas Cassel)

   - Handle errors in tegra194 BPMP transactions so we don't mistakenly
     skip future PERST# assertion (Vidya Sagar)

  AMD MDB PCIe controller driver:

   - Update DT binding example to separate PERST# to a Root Port stanza
     to make multiple Root Ports possible in the future (Sai Krishna
     Musham)

   - Add driver support for PERST# being described in a Root Port
     stanza, falling back to the host bridge if not found there (Sai
     Krishna Musham)

  Freescale i.MX6 PCIe controller driver:

   - Enable the 3.3V Vaux supply if available so devices can request
     wakeup with either Beacon or WAKE# (Richard Zhu)

  MediaTek PCIe Gen3 controller driver:

   - Add optional sys clock ready time setting to avoid sys_clk_rdy
     signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)

   - Add DT binding and driver support for MT6991 and MT8196
     (AngeloGioacchino Del Regno)

  NVIDIA Tegra PCIe controller driver:

   - When asserting PERST#, disable the controller instead of mistakenly
     disabling the PLL twice (Nagarjuna Kristam)

   - Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
     nesting error (Marek Vasut)

  Qualcomm PCIe controller driver:

   - Select PCI Power Control Slot driver so slot voltage rails can be
     turned on/off if described in Root Port devicetree node (Qiang Yu)

   - Parse only PCI bridge child nodes in devicetree, skipping unrelated
     nodes such as OPP (Operating Performance Points), which caused
     probe failures (Krishna Chaitanya Chundru)

   - Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)

   - Consolidate Root Port 'phy' and 'reset' properties in struct
     qcom_pcie_port, regardless of whether we got them from the Root
     Port node or the host bridge node (Manivannan Sadhasivam)

   - Fetch and map the ELBI register space in the DWC core rather than
     in each driver individually (Krishna Chaitanya Chundru)

   - Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
     Shift Feature' and use this in the qcom driver (Krishna Chaitanya
     Chundru)

   - Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
     Chundru)

   - Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
     Glymur, which is compatible with X1E80100 but doesn't have the
     cnoc_sf_axi clock (Qiang Yu)

  Renesas R-Car PCIe controller driver:

   - Fix a typo that prevented correct PHY initialization (Marek Vasut)

   - Add a missing 1ms delay after PWR reset assertion as required by
     the V4H manual (Marek Vasut)

   - Assure reset has completed before DBI access to avoid SError (Marek
     Vasut)

   - Fix inverted PHY initialization check, which sometimes led to
     timeouts and failure to start the controller (Marek Vasut)

   - Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
     regression when converting to msi_create_parent_irq_domain()
     (Claudiu Beznea)

   - Drop the spinlock protecting the PMSR register - it's no longer
     required since pci_lock already serializes accesses (Marek Vasut)

   - Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
     nesting error (Marek Vasut)

  SOPHGO PCIe controller driver:

   - Check for existence of struct cdns_pcie.ops before using it to
     allow Cadence drivers that don't need to supply ops (Chen Wang)

   - Add DT binding and driver for the SOPHGO SG2042 PCIe controller
     (Chen Wang)

  STMicroelectronics STM32MP25 PCIe controller driver:

   - Update pinctrl documentation of initial states and use in runtime
     suspend/resume (Christian Bruel)

   - Add pinctrl_pm_select_init_state() for use by stm32 driver, which
     needs it during resume (Christian Bruel)

   - Add devicetree bindings and drivers for the STMicroelectronics
     STM32MP25 in host and endpoint modes (Christian Bruel)

  Synopsys DesignWare PCIe controller driver:

   - Add support for x16 in devicetree 'num-lanes' property (Konrad
     Dybcio)

   - Verify that if DT specifies a single IRQ for all eDMA channels, it
     is named 'dma' (Niklas Cassel)

  TI J721E PCIe driver:

   - Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
     Vadapalli)

   - Power controller off before configuring the glue layer so the
     controller latches the correct values on power-on (Siddharth
     Vadapalli)

  TI Keystone PCIe controller driver:

   - Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
     exits with error (Siddharth Vadapalli)

   - Add Peripheral Virtualization Unit (PVU), which restricts DMA from
     PCIe devices to specific regions of host memory, to the ti,am65
     binding (Jan Kiszka)

  Xilinx NWL PCIe controller driver:

   - Clear bootloader E_ECAM_CONTROL before merging in the new driver
     value to avoid writing invalid values (Jani Nurminen)"

6093a688a0 Char/Misc/IIO/Binder changes for 6.18-rc1
Here is the big set of char/misc/iio and other driver subsystem changes
 for 6.18-rc1.  Loads of different stuff in here, it was a busy
 development cycle in lots of different subsystems, with over 27k new
 lines added to the tree.  Included in here are:
   - IIO updates including new drivers, reworking of existing apis, and
     other goodness in the sensor subsystems
   - MEI driver updates and additions
   - NVMEM driver updates
   - slimbus removal for an unused driver and some other minor
     updates
   - coresight driver updates and additions
   - MHI driver updates
   - comedi driver updates and fixes
   - extcon driver updates
   - interconnect driver additions
   - eeprom driver updates and fixes
   - minor UIO driver updates
   - tiny W1 driver updates
 
 But the majority of new code is in the rust bindings and additions,
 which includes:
   - misc driver rust binding updates for read/write support, we can now
     write "normal" misc drivers in rust fully, and the sample driver
     shows how this can be done.
   - Initial framework for USB driver rust bindings, which are disabled
     for now in the build, due to limited support, but coming in through
     this tree due to dependencies on other rust binding changes that
     were in here.  I'll be enabling these back on in the build in the
     usb.git tree after -rc1 is out so that developers can continue to
     work on these in linux-next over the next development cycle.
   - Android Binder driver implemented in Rust.  This is the big one, and
     was driving a huge majority of the rust binding work over the past
     years.  Right now there are 2 binder drivers in the kernel, selected
     only at build time as to which one to use as binder wants to be
     included in the system at boot time.  The binder C maintainers all
     agreed on this, as eventually, they want the C code to be removed from
     the tree, but it will take a few releases to get there while both
     are maintained to ensure that the rust implementation is fully
     stable and compliant with the existing userspace apis.
 
 All of these have been in linux-next for a while, with only minor merge
 issues showing up (you will hit them as well.)  Just accept both sides
 of the merge, it's just some header and include file lines, nothing
 major.

c6006b8ca1 USB/Thunderbolt changes for 6.18-rc1
Here is the big set of USB and thunderbolt drivers for 6.18-rc1.  It was
 another normal development cycle, with lots of the usual drivers getting
 updates:
   - Thunderbolt driver cleanups and additions
   - dwc3 driver updates
   - dwc2 driver updates
   - typec driver updates
   - xhci driver updates and additions
   - offload USB engine updates for better power management
   - unused tracepoint removals
   - usb gadget fixes and updates as more users start to rely on these
     drivers instead of the "old" function gadget drivers
   - new USB device ids
   - other minor driver USB driver updates
   - new USB I/O driver framework and driver additions
 
 The last item, the usb i/o driver, has an i2c and gpio driver added
 through this tree.  Those drivers were acked by the respective subsystem
 maintainers, but you will get a merge conflict with the i2c tree where
 new drivers were added in the same places in a Kconfig and Makefile.
 The merge conflict is simple, just take both sides.
 
 All of these have been in linux-next for a while, with the only issue
 being the i2c tree merge conflicts.

86bcf7be1e RISC-V updates for the v6.18 merge window (part two)
Second set of RISC-V updates for the v6.18 merge window, consisting
 of:
 
 - Support for the RISC-V-standardized RPMI interface.
 
   RPMI is a platform management communication mechanism between OSes
   running on application processors, and a remote platform management
   processor.  Similar to ARM SCMI, TI SCI, etc.  This includes irqchip,
   mailbox, and clk changes.
 
 - Support for the RISC-V-standardized MPXY SBI extension.
 
   MPXY is a RISC-V-specific standard implementing a shared memory
   mailbox between S-mode operating systems (e.g., Linux) and M-mode
   firmware (e.g., OpenSBI).  It is part of this PR since one of its
   use cases is to enable M-mode firmware to act as a single RPMI client
   for all RPMI activity on a core (including S-mode RPMI activity).
   Includes a mailbox driver.
 
 - Some ACPI-related updates to enable the use of RPMI and MPXY.
 
 - The addition of Linux-wide memcpy_{from,to}_le32() static inline
   functions, for RPMI use.
 
 - An ACPI Kconfig change to enable boot logos on any ACPI-using
   architecture (including RISC-V)
 
 - A RISC-V defconfig change to add GPIO keyboard and event device
   support, for front panel shutdown or reboot buttons
 
 This PR also includes a recent, one-line Kconfig patch from Geert to
 keep non-RISC-V users from being asked about building the RPMI virtual
 clock driver when !COMPILE_TEST.  THere's nothing preventing
 non-RISC-V SoCs from implementing RPMI, but until some users show up,
 let's not annoy others with it.

99fd09e01d dt-bindings: i2c: realtek,rtl9301-i2c: extend for RTL9310 support
Adjust the regex for child-node address to account for the fact that
RTL9310 supports 12 instead of only 8 SDA lines. Also, narrow this per
variant.

Add a vendor-specific property to explicitly specify the SCL line number
of the defined I2C controller/master. This is required, in particular
for RTL9310, to operate on the correct SCL for each controller. Require
this property to be specified for RTL9310.

Add compatibles for known SoC variants RTL9311, RTL9312 and RTL9313.

0395a5e8fd dt-bindings: i2c: realtek,rtl9301-i2c: fix wording and typos
Fix wording of binding description to use plural because there is not
only a single RTL9300 SoC. RTL9300 describes a whole family of Realtek
SoCs.

Add missing word 'of' in description of reg property.

Change 'SDA pin' to 'SDA line number' because the property must contain
the SDA (channel) number ranging from 0-7 instead of a real pin number.

ee2fe81cdc It has been a relatively busy cycle in docsland, with changes all over:
- Bring the kernel memory-model docs into the Sphinx build in the "literal
   include" mode.
 
 - Lots of build-infrastructure work, further cleaning up long-term
   kernel-doc technical debt.  The sphinx-pre-install tool has been
   converted to Python and updated for current systems.
 
 - A new tool to detect when documents have been moved and generate HTML
   redirects; this can be used on kernel.org (or any other site hosting the
   rendered docs) to avoid breaking links.
 
 - Automated processing of the YAML files describing the netlink protocol.
 
 - A significant update of the maintainer's PGP guide.
 
 ...and a seemingly endless series of typo fixes, build-problem fixes, etc.
