ad9c6ee642 Merge tag 'spi-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
 "The overwhelming bulk of this pull request is a change from Uwe
  Kleine-König which changes the return type of the remove() function to
  void as part of some wider work he's doing to do this for all bus
  types, causing updates to most SPI device drivers. The branch with
  that on has been cross merged with a couple of other trees which added
  new SPI drivers this cycle, I'm not expecting any build issues
  resulting from the change.

  Otherwise it's been a relatively quiet release with some new device
  support, a few minor features and the welcome completion of the
  conversion of the subsystem to use GPIO descriptors rather than
  numbers:

   - Change return type of remove() to void.

   - Completion of the conversion of SPI controller drivers to use GPIO
     descriptors rather than numbers.

   - Quite a few DT schema conversions.

   - Support for multiple SPI devices on a bus in ACPI systems.

   - Big overhaul of the PXA2xx SPI driver.

   - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
     MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
     Sunplus SP7021"

[ And this is obviously where that spi change that snuck into the
  regulator tree _should_ have been :^]

f648372dfe Merge tag 'thermal-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki:
 "As far as new functionality is concerned, there is a new thermal
  driver for the Intel Hardware Feedback Interface (HFI) along with some
  intel-speed-select utility changes to support it. There are also new
  DT compatible strings for a couple of platforms, and thermal zones on
  some platforms will be registered as HWmon sensors now.

  Apart from the above, some drivers are updated (fixes mostly) and
  there is a new piece of documentation for the Intel DPTF (Dynamic
  Power and Thermal Framework) sysfs interface.

  Specifics:

   - Add a new thermal driver for the Intel Hardware Feedback Interface
     (HFI) including the HFI initialization, HFI notification interrupt
     handling and sending CPU capabilities change messages to user space
     via the thermal netlink interface (Ricardo Neri, Srinivas
     Pandruvada, Nathan Chancellor, Randy Dunlap).

   - Extend the intel-speed-select utility to handle out-of-band CPU
     configuration changes and add support for the CPU capabilities
     change messages sent over the thermal netlink interface by the new
     HFI thermal driver to it (Srinivas Pandruvada).

   - Convert the DT bindings to yaml format for the Exynos platform and
     fix and update the MAINTAINERS file for this driver (Krzysztof
     Kozlowski).

   - Register the thermal zones as HWmon sensors for the QCom's Tsens
     driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour).

   - Add the msm8953 compatible documentation in the bindings (Luca
     Weiss).

   - Add the sm8150 platform support to the QCom LMh driver's DT binding
     (Thara Gopinath).

   - Check the command result from the IPC command to the BPMP in the
     Tegra driver (Mikko Perttunen).

   - Silence the error for normal configuration where the interrupt is
     optionnal in the Broadcom thermal driver (Florian Fainelli).

   - Remove remaining dead code from the TI thermal driver (Yue
     Haibing).

   - Don't use bitmap_weight() in end_power_clamp() in the powerclamp
     driver (Yury Norov).

   - Update the OS policy capabilities handshake in the int340x thermal
     driver (Srinivas Pandruvada).

   - Increase the policies bitmap size in int340x (Srinivas Pandruvada).

   - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
     int340x thermal driver (Rafael Wysocki).

   - Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang).

   - Add Intel Dynamic Power and Thermal Framework (DPTF) kernel
     interface documentation (Srinivas Pandruvada).

   - Fix bullet list warning in the thermal documentation (Randy
     Dunlap)"

Pull ACPI updates from Rafael Wysocki:
 "From the new functionality perspective, the most significant items
  here are the new driver for the 'ARM Generic Diagnostic Dump and
  Reset' device, the extension of fine grain fan control in the ACPI fan
  driver, and the change making it possible to use CPPC information to
  obtain CPU capacity.

  There are also a few new quirks, a bunch of fixes, including the
  platform-level _OSC handling change to make it actually take the
  platform firmware response into account, some code and documentation
  cleanups, and a notable update of the ACPI device enumeration
  documentation.

  Specifics:

   - Use uintptr_t and offsetof() in the ACPICA code to avoid compiler
     warnings regarding NULL pointer arithmetic (Rafael Wysocki).

   - Fix possible NULL pointer dereference in acpi_ns_walk_namespace()
     when passed "acpi=off" in the command line (Rafael Wysocki).

   - Fix and clean up acpi_os_read/write_port() (Rafael Wysocki).

   - Introduce acpi_bus_for_each_dev() and use it for walking all ACPI
     device objects in the Type C code (Rafael Wysocki).

   - Fix the _OSC platform capabilities negotioation and prevent CPPC
     from being used if the platform firmware indicates that it not
     supported via _OSC (Rafael Wysocki).

   - Use ida_alloc() instead of ida_simple_get() for ACPI enumeration of
     devices (Rafael Wysocki).

   - Add AGDI and CEDT to the list of known ACPI table signatures (Ilkka
     Koskinen, Robert Kiraly).

   - Add power management debug messages related to suspend-to-idle in
     two places (Rafael Wysocki).

   - Fix __acpi_node_get_property_reference() return value and clean up
     that function (Andy Shevchenko, Sakari Ailus).

   - Fix return value of the __setup handler in the ACPI PM timer clock
     source driver (Randy Dunlap).

   - Clean up double words in two comments (Tom Rix).

   - Add "skip i2c clients" quirks for Lenovo Yoga Tablet 1050F/L and
     Nextbook Ares 8 (Hans de Goede).

   - Clean up frequency invariance handling on x86 in the ACPI CPPC
     library (Huang Rui).

   - Work around broken XSDT on the Advantech DAC-BJ01 board (Mark
     Cilissen).

   - Make wakeup events checks in the ACPI EC driver more
     straightforward and clean up acpi_ec_submit_event() (Rafael
     Wysocki).

   - Make it possible to obtain the CPU capacity with the help of CPPC
     information (Ionela Voinescu).

   - Improve fine grained fan control in the ACPI fan driver and
     document it (Srinivas Pandruvada).

   - Add device HID and quirk for Microsoft Surface Go 3 to the ACPI
     battery driver (Maximilian Luz).

   - Make the ACPI driver for Intel SoCs (LPSS) let the SPI driver know
     the exact type of the controller (Andy Shevchenko).

   - Force native backlight mode on Clevo NL5xRU and NL5xNU (Werner
     Sembach).

   - Fix return value of __setup handlers in the APEI code (Randy
     Dunlap).

   - Add Arm Generic Diagnostic Dump and Reset device driver (Ilkka
     Koskinen).

   - Limit printable size of BERT table data (Darren Hart).

   - Fix up HEST and GHES initialization (Shuai Xue).

   - Update the ACPI device enumeration documentation and unify the ASL
     style in GPIO-related examples (Andy Shevchenko)"

8886a57974 fpga: region: Use standard dev_release for class driver
The FPGA region class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes the
managed resource code and combines the create() and register()
functions into a single register() or register_full() function.

The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.

Pull cxl updates from Dan Williams:
 "More preparation and plumbing work in the CXL subsystem.

  From an end user perspective the highlight here is lighting up the CXL
  Persistent Memory related commands (label read / write) with the
  generic ioctl() front-end in LIBNVDIMM.

  Otherwise, the ability to instantiate new persistent and volatile
  memory regions is still on track for v5.17.

  Summary:

   - Fix support for platforms that do not enumerate every ACPI0016 (CXL
     Host Bridge) in the CHBS (ACPI Host Bridge Structure).

   - Introduce a common pci_find_dvsec_capability() helper, clean up
     open coded implementations in various drivers.

   - Add 'cxl_test' for regression testing CXL subsystem ABIs.
     'cxl_test' is a module built from tools/testing/cxl/ that mocks up
     a CXL topology to augment the nascent support for emulation of CXL
     devices in QEMU.

   - Convert libnvdimm to use the uuid API.

   - Complete the definition of CXL namespace labels in libnvdimm.

   - Tunnel libnvdimm label operations from nd_ioctl() back to the CXL
     mailbox driver. Enable 'ndctl {read,write}-labels' for CXL.

   - Continue to sort and refactor functionality into distinct driver
     and core-infrastructure buckets. For example, mailbox handling is
     now a generic core capability consumed by the PCI and cxl_test
     drivers"

  Included are:

   - habanana labs driver updates, including dma_buf usage, reviewed and
     acked by the dma_buf maintainers

   - iio driver update (going through this tree not staging as they
     really do not belong going through that tree anymore)

   - hwmon driver updates that the counter drivers needed, acked by the
     hwmon maintainer

   - xillybus driver updates

   - binder driver updates

   - extcon driver updates

f73cd9c951 Merge tag 'thermal-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki:
 "These extend the thermal trip point crossing notifications sent via
  netlink to contain the temperature causing the trip point to be
  crossed, deprecate the user space thermal governor, add new DT
  bindings to drivers, move ABI documentation to Documentation/ABI, fix
  assorted issues and clean up code.

  Specifics:

   - Constify a variable in thermal MMIO driver (Rikard Falkeborn).

   - Add the current temperature in the netlink message when crossing a
     trip point in order to prevent useless back and forth reading from
     userspace (Daniel Lezcano).

   - Add support for the 'HC' variant on PM8998 PMIC in order to support
     VADC channels on recent QCom boards (Bjorn Andersson).

   - Add support for calibration values from hardware when they are
     fused (Niklas Söderlund).

   - Fix NULL pointer dereference in the thermal_release callback when
     an error occurs in the thermal_zone_device_register() (Yuanzheng
     Song).

   - Fix use-after-free in __thermal_cooling_device_register() in the
     error path (Ziyang Xuan).

   - Fix compilation of the LMh driver when CONFIG_QCOM_SCM is not set
     (Jackie Liu).

   - Add timeout when reading a register that can block forever in
     certain circumstances in the tsens driver (Ansuel Smith).

   - Add DT binding for the reset lines and use them in the rockchip
     sensor driver (Johan Jonker).

   - Add new uniphier NX1 SoC temperature sensor (Kunihiko Hayashi).

   - Save and restore the TCC value in the int340x driver (Antoine
     Tenart).

   - Deprecate the writability of the cooling device state sysfs file
     and the user space governor (Daniel Lezcano).

   - Delete bogus length check in int340x (Dan Carpenter).

   - Use bitmap_zalloc/bitmap_free when applicable in intel_powerclamp
     (Christophe JAILLET).

   - Move thermal ABI documentation to Documentation/ABI (Mauro Carvalho
     Chehab)"
