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 * tag 'media/v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (296 commits) media: imx-mipi-csis: Check csis_fmt validity before use media: v4l2-subdev.c: clear stream field media: v4l2-ctrls-api.c: move ctrl->is_new = 1 to the correct line media: Revert "media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci" media: Revert "media: av7110: move to staging/media/deprecated/saa7146" media: imx-pxp: convert to regmap media: imx-pxp: Use non-threaded IRQ media: imx-pxp: Introduce pxp_read() and pxp_write() wrappers media: imx-pxp: Implement frame size enumeration media: imx-pxp: Pass pixel format value to find_format() media: imx-pxp: Add media controller support media: imx-pxp: Don't set bus_info manually in .querycap() media: imx-pxp: Sort headers alphabetically media: imx-pxp: add support for i.MX7D media: imx-pxp: make data_path_ctrl0 platform dependent media: imx-pxp: disable LUT block media: imx-pxp: explicitly disable unused blocks media: imx-pxp: extract helper function to setup data path media: imx-pxp: detect PXP version media: dt-bindings: media: fsl-pxp: convert to yaml ...

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)" * tag 'thermal-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (135 commits) thermal/drivers/st: Remove syscfg based driver thermal: Remove core header inclusion from drivers tools/lib/thermal: Fix include path for libnl3 in pkg-config file. thermal/drivers/hisi: Drop second sensor hi3660 thermal/drivers/rcar_gen3_thermal: Fix device initialization thermal/drivers/rcar_gen3_thermal: Create device local ops struct thermal/drivers/rcar_gen3_thermal: Do not call set_trips() when resuming thermal/drivers/rcar_gen3: Add support for R-Car V4H dt-bindings: thermal: rcar-gen3-thermal: Add r8a779g0 support thermal/drivers/mediatek: Add the Low Voltage Thermal Sensor driver dt-bindings: thermal: mediatek: Add LVTS thermal controllers thermal/drivers/mediatek: Relocate driver to mediatek folder tools/lib/thermal: Fix thermal_sampling_exit() Documentation: powerclamp: Fix numbered lists formatting Documentation: powerclamp: Escape wildcard in cpumask description Documentation: admin-guide: Add toctree entry for thermal docs thermal: intel: powerclamp: Add two module parameters Documentation: admin-guide: Move intel_powerclamp documentation thermal: core: Use sysfs_emit_at() instead of scnprintf() thermal: intel: powerclamp: Fix duration module parameter ...

2023-02-16tty: n_gsm: add keep alive supportDaniel Starke1-0/+19
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.

2023-02-02platform/surface: aggregator: Rename top-level request functions to avoid ↵Maximilian Luz1-4/+4
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() Link: https://lore.kernel.org/all/085e0ada65c11da9303d07e70c510dc45f21315b.1656756450.git.mchehab@kernel.org/ Link: https://github.com/sphinx-doc/sphinx/pull/8313 Signed-off-by: Maximilian Luz <luzmaximilian@gmail.com> Link: https://lore.kernel.org/r/20221220175608.1436273-2-luzmaximilian@gmail.com Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "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" * tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits) device property: Fix documentation for fwnode_get_next_parent() firmware_loader: fix up to_fw_sysfs() to preserve const usb.h: take advantage of container_of_const() device.h: move kobj_to_dev() to use container_of_const() container_of: add container_of_const() that preserves const-ness of the pointer driver core: fix up missed drivers/s390/char/hmcdrv_dev.c class.devnode() conversion. driver core: fix up missed scsi/cxlflash class.devnode() conversion. driver core: fix up some missing class.devnode() conversions. driver core: make struct class.devnode() take a const * driver core: make struct class.dev_uevent() take a const * cacheinfo: Remove of_node_put() for fw_token device property: Add a blank line in Kconfig of tests device property: Rename goto label to be more precise device property: Move PROPERTY_ENTRY_BOOL() a bit down device property: Get rid of __PROPERTY_ENTRY_ARRAY_EL*SIZE*() kernfs: fix all kernel-doc warnings and multiple typos driver core: pass a const * into of_device_uevent() kobject: kset_uevent_ops: make name() callback take a const * kobject: kset_uevent_ops: make filter() callback take a const * kobject: make kobject_namespace take a const * ...

The biggest addition is the readdition of support for detailed configuration of the timings around chip selects.

We've just one framework addition and the rest is all new device support, fixes and cleanups. The framework addition is an API for requesting all regulators defined in DT, this isn't great practice but has reasonable applications when there is generic code handling devices on buses where the bus specification doesn't include power. The immediate application is MDIO but I believe there's others, it's another API that'll need an eye keeping on it for undesirable usage.

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.
