git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "The big change in this release is the addition of Rust bindings from Daniel Almeida, allowing fairly basic consumer use with support for enable and voltage setting operations.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "There's one new driver (Apple SMC) and extensions to existing drivers for supporting new HW models. A lot of different impovements across drivers and in core GPIO code. Details on that are in the signed tag as usual. We managed to remove some of the legacy APIs. Arnd Bergmann started to work on making the legacy bits optional so that we may compile them only for older platforms that still really need them. Rob Herring has done a lot of work to convert legacy .txt dt-bindings for GPIO controllers to YAML. There are only a few left now in the GPIO tree. A big part of the commits in this PR concern the conversion of GPIO drivers to using the new line value setter callbacks. This conversion is now complete treewide (unless I've missed something) and once all the changes from different trees land in mainline, I'll send you another PR containing a commit dropping the legacy callbacks from the tree. As the quest to pay back technical dept never really ends, we're starting another set of interface conversions, this time it's about moving fields specific to only a handful of drivers using the gpio-mmio helper out of the core gpio_chip structure that every controller implements and uses. This cycle we introduce a new set of APIs and convert a few drivers under drivers/gpio/, next cycle we'll convert remaining modules treewide (in gpio, pinctrl and mfd trees) and finally remove the old interfaces and move the gpio-mmio fields into their own structure wrapping gpio_chip. One last change I should mention here is the rework of the sysfs interface. In 2016, we introduced the GPIO character device as the preferred alternative to the sysfs class under /sys/class/gpio. While it has seen a wide adoption with the help of its user-space counterpart - libgpiod - there are still users who prefer the simplicity of sysfs. As far as the GPIO subsystem is concerned, the problem is not the existince of the GPIO class as such but rather the fact that it exposes the global GPIO numbers to the user-space, stopping us from ever being able to remove the numberspace from the kernel. To that end, this release we introduced a parallel, limited sysfs interface that doesn't expose these numbers and only implements a subset of features that are relevant to the existing users. This is a result of several discussions over the course of last year and should allow us to remove the legacy part some time in the future. Summary: GPIOLIB core: - introduce a parallel, limited sysfs user ABI that doesn't expose the global GPIO numbers to user-space while maintaining backward compatibility with the end goal of it completely replacing the existing interface, allowing us to remove it - remove the legacy devm_gpio_request() routine which has no more users - start the process of allowing to compile-out the legacy parts of the GPIO core for users who don't need it by introducing a new Kconfig option: GPIOLIB_LEGACY - don't use global GPIO numbers in debugfs output from the core code (drivers still do it, the work is ongoing) - start the process of moving the fields specific to the gpio-mmio helper out of the core struct gpio_chip into their own structure that wraps it: create a new header with modern interfaces and convert several drivers to using it - remove the platform data structure associated with the gpio-mmio helper from the kernel after having converted all remaining users to generic device properties - remove legacy struct gpio definition as it has no more users New drivers: - add the GPIO driver for the Apple System Management Controller Driver improvements: - add support for new models to gpio-adp5585, gpio-tps65219 and gpio-pca953x - extend the interrupt support in gpio-loongson-64bit - allow to mark the simulated GPIO lines as invalid in gpio-sim - convert all remaining GPIO drivers to using the new GPIO value setter callbacks - convert gpio-rcar to using simple device power management ops callbacks - don't check if current direction of a line is output before setting the value in gpio-pisosr and ti-fpc202: the GPIO core already handles that - also drop unneeded GPIO range checks in drivers, the core already makes sure we're within bounds when calling driver callbacks - use dev_fwnode() where applicable across GPIO drivers - set line value in gpio-zynqmp-modepin and gpio-twl6040 when the user wants to change direction of the pin to output even though these drivers don't need to do anything else to actually set the direction, otherwise a call like gpiod_direction_output(d, 1) will not result in the line driver high - remove the reduntant call to pm_runtime_mark_last_busy() from gpio-arizona - use lock guards in gpio-cadence and gpio-mxc - check the return values of regmap functions in gpio-wcd934x and gpio-tps65912 - use better regmap interfaces in gpio-wcove and gpio-pca953x - remove dummy GPIO chip callbacks from several drivers in cases where the GPIO core can already handle their absence - allow building gpio-palmas as a module Fixes: - use correct bit widths (according to the documentation) in gpio-virtio Device-tree bindings: - convert several of the legacy .txt documents for many different devices to YAML, improving automatic validation - create a "trivial" GPIO DT schema that covers a wide range of simple hardware that share a set of basic GPIO properties - document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander - document a new model for pca95xx - add and/or remove properties in YAML documents for gpio-rockchip, fsl,qoriq-gpio, arm,pl061 and gpio-xilinx Misc: - some minor refactoring in several places, adding/removing forward declarations, moving defines to better places, constify the arguments in some functions, remove duplicate includes, etc. - documentation updates" * tag 'gpio-updates-for-v6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (202 commits) MIPS: alchemy: gpio: use new GPIO line value setter callbacks for the remaining chips gpiolib: enable CONFIG_GPIOLIB_LEGACY even for !GPIOLIB gpio: virtio: Fix config space reading. gpiolib: make legacy interfaces optional dt-bindings: gpio: rockchip: Allow use of a power-domain gpiolib: of: add forward declaration for struct device_node power: reset: macsmc-reboot: Add driver for rebooting via Apple SMC gpio: Add new gpio-macsmc driver for Apple Macs mfd: Add Apple Silicon System Management Controller soc: apple: rtkit: Make shmem_destroy optional dt-bindings: mfd: Add Apple Mac System Management Controller dt-bindings: power: reboot: Add Apple Mac SMC Reboot Controller dt-bindings: gpio: Add Apple Mac SMC GPIO block gpio: cadence: Remove duplicated include in gpio-cadence.c gpio: tps65219: Add support for TI TPS65214 PMIC gpio: tps65219: Update _IDX & _OFFSET macro prefix gpio: sysfs: Fix an end of loop test in gpiod_unexport() dt-bindings: gpio: Convert qca,ar7100-gpio to DT schema dt-bindings: gpio: Convert maxim,max3191x to DT schema dt-bindings: gpio: fsl,qoriq-gpio: Add missing mpc8xxx compatibles ...

6 daysdt-bindings: gpio: rockchip: Allow use of a power-domainJonas Karlman
The GPIO controllers in most Rockchip SoCs are part of power domains that are always powered on, i.e. PD_BUS or PD_PMU. These always powered on power domains have typically not been described in the device tree. Because these power domains have been left out of the device tree there has not been any real need to properly describe the GPIO controllers power domain. On RK3528 the GPIO controllers are spread out among the described PD_RKVENC, PD_VO and PD_VPU power domains. However, one GPIO controller belong to an undescribed always powered on power domain. Add support to describe an optional power-domains for the GPIO controllers in Rockchip SoCs.

13 daysdt-bindings: thermal: rockchip: document otp thermal trimNicolas Frattaroli
Several Rockchip SoCs, such as the RK3576, can store calibration trim data for thermal sensors in OTP cells. This capability should be documented. Such a rockchip thermal sensor may reference cell handles that store both a chip-wide trim for all the sensors, as well as cell handles for each individual sensor channel pointing to that specific sensor's trim value. Additionally, the thermal sensor may optionally reference cells which store the base in terms of degrees celsius and decicelsius that the trim is relative to. Each SoC that implements this appears to have a slightly different combination of chip-wide trim, base, base fractional part and per-channel trim, so which ones do which is documented in the bindings.

14 daysASoC: dt-bindings: qcom,lpass-va-macro: Define clock-names in top-levelKrzysztof Kozlowski
Device variants use different amount of clock inputs, but all of them are in the same order, 'clock-names' in top-level properties can define the list and each if:then: block can only narrow the number of items. This is preferred syntax, because it keeps list unified among devices and encourages adding new entries to the end of the list, instead of adding them in the middle. The change has no functional impact, but partially reverts approach implemented in commit cfad817095e1 ("ASoC: dt-bindings: qcom,lpass-va-macro: Add missing NPL clock").
