git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "We have a new GPIO multiplexer driver, bunch of driver updates and refactoring in the core GPIO library. GPIO core: - teach gpiolib to work with software nodes for HW description - remove ARCH_NR_GPIOS treewide as we no longer impose any limit on the number of GPIOS since the allocation became entirely dynamic - add support for HW quirks for Cirrus CS42L56 codec, Marvell NFC controller, Freescale PCIe and Ethernet controller, Himax LCDs and Mediatek mt2701 - refactor OF quirk code - some general refactoring of the OF and ACPI code, adding new helpers, minor tweaks and fixes, making fwnode usage consistent etc. GPIO uAPI: - fix an issue where the user-space can trigger a NULL-pointer dereference in the kernel by opening a device file, forcing a driver unbind and then calling one of the syscalls on the associated file descriptor New drivers: - add gpio-latch: a new GPIO multiplexer based on latches connected to other GPIOs Driver updates: - convert i2c GPIO expanders to using .probe_new() - drop the gpio-sta2x11 driver - factor out common code for the ACCES IDIO-16 family of controllers and use this new library wherever applicable in drivers - add DT support to gpio-hisi - allow building gpio-davinci as a module and increase its maxItems property - add support for a new model to gpio-pca9570 - other minor changes to various drivers" * tag 'gpio-updates-for-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (66 commits) gpio: sim: set a limit on the number of GPIOs gpiolib: protect the GPIO device against being dropped while in use by user-space gpiolib: cdev: fix NULL-pointer dereferences gpiolib: Provide to_gpio_device() helper gpiolib: Unify access to the device properties gpio: Do not include <linux/kernel.h> when not really needed. gpio: pcf857x: Convert to i2c's .probe_new() gpio: pca953x: Convert to i2c's .probe_new() gpio: max732x: Convert to i2c's .probe_new() dt-bindings: gpio: gpio-davinci: Increase maxItems in gpio-line-names gpiolib: ensure that fwnode is properly set gpio: sl28cpld: Replace irqchip mask_invert with unmask_base gpiolib: of: Use correct fwnode for DT-probed chips gpiolib: of: Drop redundant check in of_mm_gpiochip_remove() gpiolib: of: Prepare of_mm_gpiochip_add_data() for fwnode gpiolib: add support for software nodes gpiolib: consolidate GPIO lookups gpiolib: acpi: avoid leaking ACPI details into upper gpiolib layers gpiolib: acpi: teach acpi_find_gpio() to handle data-only nodes gpiolib: acpi: change acpi_find_gpio() to accept firmware node ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl 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.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "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. Summary: - 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" * tag 'spi-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (66 commits) spi: dt-bindings: Convert Synquacer SPI to DT schema spi: spi-gpio: Don't set MOSI as an input if not 3WIRE mode spi: spi-mtk-nor: Add recovery mechanism for dma read timeout spi: spi-fsl-lpspi: add num-cs binding for lpspi spi: spi-fsl-lpspi: support multiple cs for lpspi spi: mtk-snfi: Add snfi support for MT7986 IC spi: spidev: mask SPI_CS_HIGH in SPI_IOC_RD_MODE spi: cadence-quadspi: Add minimum operable clock rate warning to baudrate divisor calculation spi: microchip: pci1xxxx: Add suspend and resume support for PCI1XXXX SPI driver spi: dt-bindings: nuvoton,wpcm450-fiu: Fix warning in example (missing reg property) spi: dt-bindings: nuvoton,wpcm450-fiu: Fix error in example (bogus include) spi: mediatek: Enable irq when pdata is ready spi: spi-mtk-nor: Unify write buffer on/off spi: intel: Add support for SFDP opcode spi: intel: Take possible chip address into account in intel_spi_read/write_reg() spi: intel: Implement adjust_op_size() spi: intel: Use ->replacement_op in intel_spi_hw_cycle() spi: cadence: Drop obsolete dependency on COMPILE_TEST spi: Add Nuvoton WPCM450 Flash Interface Unit (FIU) bindings spi: wpcm-fiu: Add direct map support ...

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "Quite a quiet release for regulator, the diffstat is dominated by the I2C migration to probe_new() and the newly added MT6357 driver. 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.

2022-09-24media: mc: entity: Rewrite media_pipeline_start()Laurent Pinchart1-4/+3
[Note: the code is mostly from Laurent but the patch description is from Tomi] The media_pipeline_start() and media_pipeline_stop() functions use the media graph walk API to traverse the graph and validate the pipeline. The graph walk traverses the media graph following links between the entities. Also, while the pipeline can't change between the start and stop calls, the graph is walked again from scratch at stop time, or any time a driver needs to inspect the pipeline. With the upcoming multiplexed streams support we will need a bit more intelligent pipeline construction, as e.g. two independent streams may be passing through a single entity via separate pads in which case those pads should not be part of the same pipeline. This patch essentially rewrites the media_pipeline_start/stop so that a pipeline is defined as a set of pads instead of entities and the media graph traversal considers the pad interdependencies when choosing which links to follow. Currently all the entity's pads are considered as interdependent. This means that the behavior with all the current drivers stays the same, but in the future we can define a more fine-grained pipeline construction. Additionally the media pipeline's pads are cached at media_pipeline_start() time, and re-used at media_pipeline_stop() which avoid the need to re-walk the whole graph as the previous implementation did. Also, caching pads in the pipeline can serve in the future as the foundation to provide a better API than the media graph walk to drivers to iterate over pads and entities in the pipeline. Note that the old media_pipeline_start/stop used the media graph walk API. The new version does not use the media graph walk API, but instead a new implementation. There are two reasons for not changing the graph walk: it proved to be rather difficult to change the graph walk to have the features implemented in this patch, and second, this keeps the backward compatibility of the graph walk as there are users of the graph walk API The long term plan is that all the existing code would be converted to use the new cached pipeline, thus allowing us to remove the graph walk.

The doc talks about streams and pipelines, but doesn't really define them. This is an attempt to define them according to my understanding.

The devm_of_pwm_get() has recently lost its single user, drop the dead API as well. Note, the new code should use either plain pwm_get() or managed devm_pwm_get() or devm_fwnode_pwm_get() APIs.
