Merge tag 'media/v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
   stkwebcam, tm6000, vpfe_capture and zr364xx

 - saa7146 recovered from staging/deprecated. We opted to give ti a
   chance, and, instead of deprecating it, the intention is to write
   patches migrating it from VB1 to VB2.

 - av7110 returned from staging/deprecated/ to staging/ as we're not
   planning on dropping it any time soon

 - media controller API has gained experimental support for G_ROUTING
   and streams API. No drivers use it right now. We're planning to add
   one after -rc1, giving some time to experience the API and eventually
   have changes during the next development cycle

 - New sensor drivers: imx296, imx415, ov8858

 - Atomisp had lots of changes, specially on its sensor's interface,
   making atomisp sensor drivers closer to normal sensor drivers

 - media controller kAPI has gained some helpers to traverse pipelines

 - uvcvideo now better support power line control

 - lots of bug fixes, cleanups and driver improvements

Linus Torvalds cac85e4616 VFIO updates for v6.3-rc1
- Remove redundant resource check in vfio-platform. (Angus Chen)
 
  - Use GFP_KERNEL_ACCOUNT for persistent userspace allocations, allowing
    removal of arbitrary kernel limits in favor of cgroup control.
    (Yishai Hadas)
 
  - mdev tidy-ups, including removing the module-only build restriction
    for sample drivers, Kconfig changes to select mdev support,
    documentation movement to keep sample driver usage instructions with
    sample drivers rather than with API docs, remove references to
    out-of-tree drivers in docs. (Christoph Hellwig)
 
  - Fix collateral breakages from mdev Kconfig changes. (Arnd Bergmann)
 
  - Make mlx5 migration support match device support, improve source
    and target flows to improve pre-copy support and reduce downtime.
    (Yishai Hadas)
 
  - Convert additional mdev sysfs case to use sysfs_emit(). (Bo Liu)
 
  - Resolve copy-paste error in mdev mbochs sample driver Kconfig.
    (Ye Xingchen)
 
  - Avoid propagating missing reset error in vfio-platform if reset
    requirement is relaxed by module option. (Tomasz Duszynski)
 
  - Range size fixes in mlx5 variant driver for missed last byte and
    stricter range calculation. (Yishai Hadas)
 
  - Fixes to suspended vaddr support and locked_vm accounting, excluding
    mdev configurations from the former due to potential to indefinitely
    block kernel threads, fix underflow and restore locked_vm on new mm.
    (Steve Sistare)
 
  - Update outdated vfio documentation due to new IOMMUFD interfaces in
    recent kernels. (Yi Liu)
 
  - Resolve deadlock between group_lock and kvm_lock, finally.
    (Matthew Rosato)
 
  - Fix NULL pointer in group initialization error path with IOMMUFD.

Merge tag 'thermal-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control updates from Rafael Wysocki:
 "The majority of changes here are related to the general switch-over to
  using arrays of generic trip point structures registered along with a
  thermal zone instead of trip point callbacks (this has been done
  mostly by Daniel Lezcano with some help from yours truly on the Intel
  drivers front).

  Apart from that and the related reorganization of code, there are some
  enhancements of the existing driver and a new Mediatek Low Voltage
  Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
  rework so it will use the generic idle_inject facility for CPU idle
  time injection going forward and it will take additional module
  parameters for specifying the subset of CPUs to be affected by it
  (work done by Srinivas Pandruvada).

  Also included are assorted fixes and a whole bunch of cleanups.

  Specifics:

   - Rework a large bunch of drivers to use the generic thermal trip
     structure and use the opportunity to do more cleanups by removing
     unused functions from the OF code (Daniel Lezcano)

   - Remove core header inclusion from drivers (Daniel Lezcano)

   - Fix some locking issues related to the generic thermal trip rework
     (Johan Hovold)

   - Fix a crash when requesting the critical temperature on tegra,
     which is related to the generic trip point work (Jon Hunter)

   - Clean up thermal device unregistration code (Viresh Kumar)

   - Fix and clean up thermal control core initialization error code
     paths (Daniel Lezcano)

   - Relocate the trip points handling code into a separate file (Daniel
     Lezcano)

   - Make the thermal core fail registration of thermal zones and
     cooling devices if the thermal class has not been registered
     (Rafael Wysocki)

   - Add trip point initialization helper functions for ACPI-defined
     trip points and modify two thermal drivers to use them (Rafael
     Wysocki, Daniel Lezcano)

   - Make the core thermal control code use sysfs_emit_at() instead of
     scnprintf() where applicable (ye xingchen)

   - Consolidate code accessing the Intel TCC (Thermal Control
     Circuitry) MSRs by introducing library functions for that and
     making the TCC-related code in thermal drivers use them (Zhang Rui)

   - Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
     changes (Zhang Rui)

   - Address an "unsigned expression compared with zero" warning in the
     intel_soc_dts_iosf thermal driver (Yang Li)

   - Update comments regarding two functions in the Intel Menlow thermal
     driver (Deming Wang)

   - Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
     driver (ye xingchen)

   - Make the intel_pch thermal driver support the Wellsburg PCH (Tim
     Zimmermann)

   - Modify the intel_pch and processor_thermal_device_pci thermal
     drivers use generic trip point tables instead of thermal zone trip
     point callbacks (Daniel Lezcano)

   - Add production mode attribute sysfs attribute to the int340x
     thermal driver (Srinivas Pandruvada)

   - Rework dynamic trip point updates handling and locking in the
     int340x thermal driver (Rafael Wysocki)

   - Make the int340x thermal driver use a generic trip points table
     instead of thermal zone trip point callbacks (Rafael Wysocki,
     Daniel Lezcano)

   - Clean up and improve the int340x thermal driver (Rafael Wysocki)

   - Simplify and clean up the intel_pch thermal driver (Rafael Wysocki)

   - Fix the Intel powerclamp thermal driver and make it use the common
     idle injection framework (Srinivas Pandruvada)

   - Add two module parameters, cpumask and max_idle, to the Intel
     powerclamp thermal driver to allow it to affect only a specific
     subset of CPUs instead of all of them (Srinivas Pandruvada)

   - Make the Intel quark_dts thermal driver Use generic trip point
     objects instead of its own trip point representation (Daniel
     Lezcano)

   - Add toctree entry for thermal documents and fix two issues in the
     Intel powerclamp driver documentation (Bagas Sanjaya)

   - Use strscpy() to instead of strncpy() in the thermal core (Xu
     Panda)

   - Fix thermal_sampling_exit() (Vincent Guittot)

   - Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam
     Chihi)

   - Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert
     Uytterhoeven)

   - Fix useless call to set_trips() when resuming in the rcar_gen3
     thermal control driver and add interrupt support detection at init
     time to it (Niklas Söderlund)

   - Fix memory corruption in the hi3660 thermal driver (Yongqin Liu)

   - Fix include path for libnl3 in pkg-config file for libthermal
     (Vibhav Pant)

   - Remove syscfg-based driver for st as the platform is not supported
     any more (Alain Volmat)"

Daniel Starke 72206cc730 tty: n_gsm: add keep alive support
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapters 5.4.6.3.4 and 5.1.8.1.3 describe the test
command which can be used to test the mux connection between both sides.

Currently, no algorithm is implemented to make use of this command. This
requires that each multiplexed upper layer protocol supervises the
underlying muxer connection to handle possible connection losses.

Introduce ioctl commands and functions to optionally enable keep alive
handling via the test command as described in chapter 5.4.6.3.4. A single
incrementing octet "ka_num" is being used for unique identification of each
single keep alive packet. Retries will use the same "ka_num" value as the
original packet. Retry count and interval are taken from the general
parameters N2 and T2.

Add usage description and basic example for the new ioctl to the n_gsm
documentation.

Note that support for the test command is mandatory and already present in
the muxer implementation since the very first version.
Also note that the previous ioctl structure gsm_config cannot be extended
due to missing checks against zero of the field "unused".

Maximilian Luz b09ee1cd59 platform/surface: aggregator: Rename top-level request functions to avoid ambiguities
We currently have a struct ssam_request_sync and a function
ssam_request_sync(). While this is valid C, there are some downsides to
it.

One of these is that current Sphinx versions (>= 3.0) cannot
disambiguate between the two (see disucssion and pull request linked
below). It instead emits a "WARNING: Duplicate C declaration" and links
for the struct and function in the resulting documentation link to the
same entry (i.e. both to either function or struct documentation)
instead of their respective own entries.

While we could just ignore that and wait for a fix, there's also a point
to be made that the current naming can be somewhat confusing when
searching (e.g. via grep) or trying to understand the levels of
abstraction at play:

We currently have struct ssam_request_sync and associated functions
ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct.
However, function ssam_request_sync() is one abstraction level above
this. Similarly, ssam_request_sync_with_buffer() is not a function
operating on struct ssam_request_sync, but rather a sibling to
ssam_request_sync(), both using the struct under the hood.

Therefore, rename the top level request functions:

  ssam_request_sync() -> ssam_request_do_sync()
  ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer()
  ssam_request_sync_onstack() -> ssam_request_do_sync_onstack()

Andy Shevchenko af6f64c68b pinctrl: Proofreading and updating the documentation accordingly
Proofreading and updating the documentation accordingly, i.e. fixed:

  - ambiguity of foo_set_mux() implementation and explanations
  - semantics in some of the examples, e.g. _probe() --> _init()
  - references to the callbacks to make them start with dot
  - references to the legacy API by replacing them with newer one
  - indentation in some of the examples
  - double words or phrases

updated:

  - unsigned --> unsigned int in some of the examples
  - use struct pingroup and PINCTRL_PINGROUP() in some of the examples
  - use struct pinfunction and PINCTRL_PINFUNCTION() in some of the examples

and enabled:

  - syntax highlighting for the examples in the programming languages
  - chapter references

Yet to clarify:

  - "gpioN" menton for the default function when requesting GPIO

Linus Torvalds 71a7507afb Driver Core changes for 6.2-rc1
Here is the set of driver core and kernfs changes for 6.2-rc1.
 
 The "big" change in here is the addition of a new macro,
 container_of_const() that will preserve the "const-ness" of a pointer
 passed into it.
 
 The "problem" of the current container_of() macro is that if you pass in
 a "const *", out of it can comes a non-const pointer unless you
 specifically ask for it.  For many usages, we want to preserve the
 "const" attribute by using the same call.  For a specific example, this
 series changes the kobj_to_dev() macro to use it, allowing it to be used
 no matter what the const value is.  This prevents every subsystem from
 having to declare 2 different individual macros (i.e.
 kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce
 the const value at build time, which having 2 macros would not do
 either.
 
 The driver for all of this have been discussions with the Rust kernel
 developers as to how to properly mark driver core, and kobject, objects
 as being "non-mutable".  The changes to the kobject and driver core in
 this pull request are the result of that, as there are lots of paths
 where kobjects and device pointers are not modified at all, so marking
 them as "const" allows the compiler to enforce this.
 
 So, a nice side affect of the Rust development effort has been already
 to clean up the driver core code to be more obvious about object rules.
 
 All of this has been bike-shedded in quite a lot of detail on lkml with
 different names and implementations resulting in the tiny version we
 have in here, much better than my original proposal.  Lots of subsystem
 maintainers have acked the changes as well.
 
 Other than this change, included in here are smaller stuff like:
   - kernfs fixes and updates to handle lock contention better
   - vmlinux.lds.h fixes and updates
   - sysfs and debugfs documentation updates
   - device property updates
 
 All of these have been in the linux-next tree for quite a while with no
 problems, OTHER than some merge issues with other trees that should be
 obvious when you hit them (block tree deletes a driver that this tree
 modifies, iommufd tree modifies code that this tree also touches).  If
 there are merge problems with these trees, please let me know.

Pull pin control updates from Linus Walleij:
 "The two large chunks is the header clean-up from Andy and the Qualcomm
  DT bindings clean-up from Krzysztof. Each which could give rise to
  conflicts, but I haven't seen any.

  The YAML conversions happening around the device tree is the biggest
  item in the series and is the result of Rob Herrings ambition to
  autovalidate these trees against strict schemas and it is paying off
  in lots of bugs found and ever prettier device trees. Sooner or later
  the transition will be complete, Krzysztof is fixing up all of the
  Qualcomm stuff, which is pretty voluminous.

Linus Torvalds d0f3ad23cf spi: Updates for v6.2
A busy enough release, but not for the core which has only seen very
 small updates.  The biggest addition is the readdition of support for
 detailed configuration of the timings around chip selects.  That had
 been removed for lack of use but there's been applications found for it
 on Atmel systems.  Otherwise the updates are mostly feature additions
 and cleanups to existing drivers.
 
  - Provide a helper for getting device match data in a way that
    abstracts away which firmware interface is being used.
  - Re-add the spi_set_cs_timing() API for detailed configuration of the
    timing around chip select and support it on Atmel.
  - Support for MediaTek MT7986, Microchip PCI1xxxx, Nuvoton WPCM450 FIU
    and Socionext F_OSPI.
 
 There's a straightforward add/add conflict with the rpmsg tree in the
 xilinx firmware code (both trees got new users of the firmware added
 each needing new firmware<->kernel ioctls).
 
 There's a cross tree merge with I2C in order to use the new
 i2c_client_get_device_id() helper in some I2C attached SPI controllers
 as part of their conversion to I2C's probe_new() API.

 specification doesn't include power.  The immediate application is MDIO

Merge tag 'drm-next-2022-12-13' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for
  discrete GPUs. I think all of those should have been acked/reviewed by
  relevant parties.

Linus Torvalds a7cacfb068 This was a not-too-busy cycle for documentation; highlights include:
- The beginnings of a set of translations into Spanish, headed up by Carlos
   Bilbao.
 
 - More Chinese translations.
 
 - A change to the Sphinx "alabaster" theme by default for HTML generation.
   Unlike the previous default (Read the Docs), alabaster is shipped with
   Sphinx by default, reducing the number of other dependencies that need to
   be installed.  It also (IMO) produces a cleaner and more readable result.
 
 - The ability to render the documentation into the texinfo format
   (something Sphinx could always do, we just never wired it up until now).
 
 Plus the usual collection of typo fixes, build-warning fixes, and minor
 updates.
