| * treewide: rename GPIO set callbacks back to their original namesBartosz Golaszewski2025-08-073-3/+3
| | | | | | | | | | | | | | | | | | | | | | The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski <[email protected]>

| | * mfd: axp20x: Set explicit ID for regulator cell if no IRQ line is presentChen-Yu Tsai2025-07-241-3/+2

This didn't entirely work since on some or all of these boards, the interrupt line on this secondary PMIC was left unconnected, and thus the driver would fall back to the generic "no interrupt; only regulators" case, which didn't have the explicit ID set, thus undoing the intended fix. Also set an explicit ID for the regulator cell in the no IRQ generic fall back case. This fixes the conflict for the AXP717 + AXP313/AXP323 case. For the actual single PMIC with no IRQ connected case, the ID does not affect functionality, only the device naming of the regulator cell, and by extension the name and path under sysfs.

DEV_RST in the datasheet) or via PWRCTRL or RESETB pins. For RK806, the following values are possible for RST_FUN: 0b00 means "Restart PMU" 0b01 means "Reset all the power off reset registers, forcing the state to switch to ACTIVE mode" 0b10 means "Reset all the power off reset registers, forcing the state to switch to ACTIVE mode, and simultaneously pull down the RESETB PIN for 5mS before releasing" 0b11 means the same as for 0b10 just above. This adds the appropriate logic in the driver to parse the new rockchip,reset-mode DT property to pass this information. It just happens that the values in the binding match the values to write in the bitfield so no mapping is necessary. If it is missing, the register is left untouched and relies either on the silicon default or on whatever was set earlier in the boot stages (e.g. the bootloader).

| | * mfd: axp20x: Set explicit ID for AXP313 regulatorChen-Yu Tsai2025-07-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On newer boards featuring the A523 SoC, the AXP323 (related to the AXP313) is paired with the AXP717 and serves as a secondary PMIC providing additional regulator outputs. However the MFD cells are all registered with PLATFORM_DEVID_NONE, which causes the regulator cells to conflict with each other. Commit e37ec3218870 ("mfd: axp20x: Allow multiple regulators") attempted to fix this by switching to PLATFORM_DEVID_AUTO so that the device names would all be different, however that broke IIO channel mapping, which is also tied to the device names. As a result the change was later reverted. Instead, here we attempt to make sure the AXP313/AXP323 regulator cell does not conflict by explicitly giving it an ID number. This was previously done for the AXP809+AXP806 pair used with the A80 SoC.

Since commit 7613bc0d116a ("mfd: cros_ec: Don't load charger with UCSI") the presence of EC_FEATURE_UCSI_PPM would inhibit the probing of the charge-control driver. Furthermore recent versions of the EC firmware in Framework laptops hard-disable EC_FEATURE_USB_PD to avoid probing cros-usbpd-charger, which then also breaks cros-charge-control. Instead use the dedicated EC_FEATURE_CHARGER.

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 ...

Communication happens via a shared mailbox using the RTKit protocol which is also used for other co-processors. The SMC protocol then allows reading and writing many different keys which implement the various features. The MFD core device handles this protocol and exposes it to the sub-devices. Some of the sub-devices are potentially also useful on pre-M1 Apple machines and support for SMCs on these machines can be added at a later time.

Hence, instead of having a regmap configuration for every variant (duplicating lots of fields), add a chip info type of structure with a regmap ID to identify which defaults to use and populate regmap_config at runtime given a template plus the id. Also note that between variants, the defaults can be the same which means the chip info structure can be used in more than one compatible. This will also make it simpler adding new chips with more variants. Also note that the chip info structures are deliberately not const as they will also contain lots of members that are the same between the different devices variants and so we will fill those at runtime.

Split the driver into a transport-agnostic core ('sec-core') and transport-specific ('sec-i2c', 'sec-acpm') modules to support non-I2C devices - Merge the 'sec-core' and 'sec-irq' modules to reduce memory consumption - Move internal APIs to a private header to clean up the public API - Improve code style by sorting includes, cleaning up headers, sorting device tables, and using helper macros like 'dev_err_probe()', 'MFD_CELL', and 'REGMAP_IRQ_REG' - Make regmap configuration for s2dos05/s2mpu05 explicit to improve clarity - Rework platform data and regmap instantiation to use OF match data instead of a large switch statement ROHM BD96801/2: - Prepare the driver for new models by separating chip-specific data into its own structure - Drop IC name prefix from IRQ resource names in both the MFD and regulator drivers for simplification Broadcom BCM590xx: - Refactor the regulator driver to store descriptions in a table to ease support for new chips - Rename BCM59056-specific data to prepare for the addition of other regulators - Use 'dev_err_probe()' for cleaner error handling Exynos ACPM: - Correct kerneldoc warnings and use the conventional 'np' argument name General MFD: - Convert 'aat2870' and 'tps65010' to use the per-client debugfs directory provided by the I2C core - Convert 'sm501', 'tps65010' and 'ucb1x00' to use the new GPIO line value setter callbacks - Constify 'regmap_irq_chip' and other structures in '88pm886' to move data to read-only sections BCM590xx: - Drop the unused "id" member from the 'bcm590xx' struct in preparation for a replacement Samsung SEC Core: - Remove forward declarations for functions that no longer exist SM501: - Remove the unused 'sm501_find_clock()' function New Compatibles: - Google: Add a PMIC child node to the 'google,gs101-acpm-ipc' binding - ROHM: Add new bindings for 'rohm,bd96802-regulator' and 'rohm,bd96802-pmic', and add compatibles for BD96805 and BD96806 - Maxim: Add new bindings for 'maxim,max77759-gpio', 'maxim,max77759-nvmem', and the top-level 'maxim,max77759' -

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'struct regmap_irq_chip' is not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers. While at it, also constify some other structures.
