2022-09-25hwmon: (pwm-fan) Switch regulator dynamicallyAlexander Stein1-0/+12
This adds the enable attribute which is used to select if zero PWM duty means to switch off regulator and PWM or to keep them enabled but at inactive PWM output level. Depending on the select enable mode, turn off the regulator and PWM if the PWM duty is zero, or keep them enabled. This is especially important for fan using inverted PWM signal polarity. Having regulator supplied and PWM disabled, some PWM controllers provide the active, rather than inactive signal. With this change the shutdown as well as suspend/resume paths require modifcations as well.

Jonathan writes: Second set of IIO new device support, features and cleanup for the 6.1 cycle. Normal mixed bag of new device support with continuing trend that most new devices are supported by extending existing drivers - a positive sign perhaps that device manufacturers have somewhat stabilized their interfaces across product generations. The BNO055 driver was however a substantial addition including several additions to the IIO core. There are a number of significant patch sets under review, so if the 6.0 cycle runs long I may send a 3rd pull request. New device support * adi,adxl313 - Support for the ADXL312 and ADXL314 accelerometers. * bosch,bmp280 - Support for the BMP380 family of pressures sensors. Included considerable refactoring and modernization of the bmp280 driver. * bosch,bno055 - New driver for this i2c/serial attached complex IMU. * lltc,ltc2497 - Support for the LTC2499 16 channel, 24bit ADC. * st,pressure - Support for the LPS22DF pressure sensor * st,lsm6dsx - Support for the LSM6DSTX (Mainly adding the ID and WAI) Features * core - to support the bosch,bno055 requirements - Support for linear acceleration channel type (effect of gravity removed) - Pitch, yaw and roll modifiers for angle channels. - Standard serialnumber attribute documentation. - Binary attributes - to allow for calibration save and restore. * adi,ad7923 - Support extended range (wider supported input voltage range). * bosch,bmp280 - Add filter controls for some supported parts. * microchip,mcp3911 - Buffered capture support for this ADC. - Data ready interrupt support, including hiz control for line. - Oversampling ratio support. * st,stm32-adc - Support ID registers on parts where they are present, providing discoverability of some features. Fixes - late breaking fixes that I judged could wait for the merge window. * adi,ad5593r - Add a missing STOP condition between address write and data read. - Check for related i2c functionality. * adi,ad7923 - Fix shift reporting for some variants supported by the driver. * infinion,dps310 - Work around a hardware issue where a chip can hang by adding a timeout and reset path. Cleanups * Continuing work to switch to new pm macros. * MAINTAINERS - Drop duplication of wild card covered entry in ADI block and add missing entries to cover ltc294x binding files. * bosch,bma400 - Fix trivial smatch warning. * bosch,bmp280 - Fix broken links to datasheets * lltc,ltc2497 - Fix missing entry for ltc2499 * mexelis,mlx90614 - Switch to get_avail() callback for _available attributes. * microchip,mcp3911 - Move to devm_ resource management for all elements of probe() * tag 'iio-for-6.1b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (57 commits) iio: adc: mcp3911: add support for oversampling ratio dt-bindings: iio: adc: mcp3911: add microchip,data-ready-hiz entry iio: adc: mcp3911: add support for interrupts iio: adc: mcp3911: add support for buffers iio: adc: mcp3911: use resource-managed version of iio_device_register iio: accel: bma400: Fix smatch warning based on use of unintialized value. iio: light: st_uvis25: Use EXPORT_NS_SIMPLE_DEV_PM_OPS() iio: accel: bmi088: Use EXPORT_NS_GPL_RUNTIME_DEV_PM_OPS() and pm_ptr() iio: proximity: srf04: Use pm_ptr() to remove unused struct dev_pm_ops iio: proximity: sx9360: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() iio: proximity: sx9324: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() iio: proximity: sx9310: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() docs: iio: add documentation for BNO055 driver iio: imu: add BNO055 I2C driver iio: imu: add BNO055 serdev driver dt-bindings: iio/imu: Add Bosch BNO055 iio: document "serialnumber" sysfs attribute iio: document bno055 private sysfs attributes iio: imu: add Bosch Sensortec BNO055 core driver iio: add support for binary attributes ...

2022-09-24media: dt-bindings: media: samsung,exynos5250-gsc: convert to dtschemaKrzysztof Kozlowski2-38/+109
Convert the Samsung Exynos SoC G-Scaler bindings to DT schema. Changes done during conversion: 1. A typical (already used) properties like clocks, iommus and power-domains. 2. Require clocks, because they are essential for the block to operate. 3. Describe the differences in clocks between the Exynos5250/5420 and the Exynos5433 G-Scalers. This includes the fifth Exynos5433 clock "gsd" (GSCL Smart Deck) which was added to the DTS, but not to the bindings and Linux driver. Similarly to Exynos5433 DECON change [1], the clock should be used.

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 onboard USB Hub on SC7180 Trogdor is finally described and a few ADC related updates are introduced. On SC7280 support for the CPU and LLC bwmon instances are introduced. Soundwire, audio codecs and sound introduced for a variety of boards. Using required-opps the USB controllers votes for a minimum corner on VDD_CX. The onboard USB Hub Herobrine is described. A new board, the Google Evoker is added, as is another revision of Herobrine Villager. On SC8280XP the USB controllers are marked as wakeup-sources, to keep them powered during suspend. The CRD has HID devices marked as wakeup-sources to enable resuming the system. In addition to these changes the alternative touchpad is introduced on the Lenovo ThinkPad X13s. SDM845 gains RPMh stats support and the LLCC BWMON is added. For SM6350 interconnect providers and GPI DMA is introduced. A description of the PM7280b PMIC is added to Fairphone FP4 on SM7225.
