2025-07-24dt-bindings: mfd: fsl,imx8qxp-csr: Remove binding documentationLiu Ying
commit b0a5cde57cf1 ("dt-bindings: mfd: Explain lack of child dependency in simple-mfd") pointed out that it's a mistake for a child device of a simple MFD device to depend on the simple MFD device's clock resources. fsl,imx8qxp-csr.yaml happens to make that mistake. To fix that, remove fsl,imx8qxp-csr.yaml and use "simple-pm-bus" and "syscon" as the CSR node's compatible strings in the examples of fsl,imx8qxp-pixel-link-msi-bus.yaml to replace the wrong compatible strings which include "simple-mfd" and "fsl,imx8qxp-mipi-lvds-csr". Since fsl,imx8qxp-pixel-link-msi-bus.yaml as the last user of the CSR compatible strings no longer uses them, it's safe to remove the fsl,imx8qxp-csr.yaml binding documentation.

2025-07-24mfd: axp20x: Set explicit ID for AXP313 regulatorChen-Yu Tsai
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.

2025-07-24mfd: cros_ec: Separate charge-control probing from USB-PDThomas Weißschuh
The charge-control subsystem in the ChromeOS EC is not strictly tied to its USB-PD subsystem. 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.

2025-07-24gpio: Add new gpio-macsmc driver for Apple MacsHector Martin
This driver implements the GPIO service on top of the SMC framework on Apple Mac machines. In particular, these are the GPIOs present in the PMU IC which are used to control power to certain on-board devices. Although the underlying hardware supports various pin config settings (input/output, open drain, etc.), this driver does not implement that functionality and leaves it up to the firmware to configure things properly. We also don't yet support interrupts/events. This is sufficient for device power control, which is the only thing we need to support at this point. More features will be implemented when needed. To our knowledge, only Apple Silicon Macs implement this SMC feature.

2025-07-24mfd: Add Apple Silicon System Management ControllerSven Peter
The System Management Controller (SMC) on Apple Silicon machines is a piece of hardware that exposes various functionalities such as temperature sensors, voltage/power meters, shutdown/reboot handling, GPIOs and more. 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.

Add support for adding GPIs to the event FIFO. This is done by adding irq_chip support. Like this, one can use the input gpio_keys driver as a "frontend" device and input handler. As part of this change, we now implement .request() and .free() as we can't blindly consume all available pins as GPIOs (example: some pins can be used for forming a keymap matrix). Also note that the number of pins can now be obtained from the parent, top level device. Hence the 'max_gpio' variable can be removed.

2025-07-01mfd: adp5585: Add support for event handlingNuno Sá
These devices are capable of generate FIFO based events based on KEY or GPI presses. Add support for handling these events. This is in preparation of adding full support for keymap and gpis based events.

2025-07-01dt-bindings: mfd: adp5585: add properties for input eventsNuno Sá
Add properties related to input events. These devices can act as keyboards and can support events either via a keymap Matrix or through GPIs. Note that the device needs to be an interrupt controller for GPIs based events. We specifically need a property specifying the pins used by the keymap matrix since these devices have no requirement for rows and columns to be contiguous without holes which is enforced by the standard input properties.

Add support for the adp5589 I/O expander. From a PWM point of view it is pretty similar to adp5585. Main difference is the address of registers meaningful for configuring the PWM.

2025-07-01gpio: adp5585: add support for the adp5589 expanderNuno Sá
Support the adp5589 I/O expander which supports up to 19 pins. We need to add a chip_info based struct since accessing register "banks" and "bits" differs between devices. Also some register addresses are different. While at it move ADP558X_GPIO_MAX defines to the main header file and rename them. That information will be needed by the top level device in a following change.

2025-07-01mfd: adp5585: Add a per chip reg strutureNuno Sá
There are some differences in the register map between the devices. Hence, add a register structure per device. This will be needed in following patches. On top of that adp5585_fill_regmap_config() is renamed and reworked so that the current struct adp5585_info act as template (they indeed contain all the different data between variants) which can then be complemented depending on the device (as identified by the id register). This is done like this since a lot of the data is pretty much the same between variants of the same device.

2025-07-01mfd: adp5585: Refactor how regmap defaults are handledNuno Sá
The only thing changing between variants is the regmap default registers. 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.

It is not mandatory to use all the capabilities of the device. One can very well only use it as a gpio controller without the PWM support. This will be even more evident when support for the matrix keymap is added. Hence drop the requirements for PWM and GPIO.
