git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull Char/Misc/IIO/Binder updates from Greg KH: "Here is the big set of char/misc/iio and other driver subsystem changes for 6.18-rc1. Loads of different stuff in here, it was a busy development cycle in lots of different subsystems, with over 27k new lines added to the tree. Included in here are: - IIO updates including new drivers, reworking of existing apis, and other goodness in the sensor subsystems - MEI driver updates and additions - NVMEM driver updates - slimbus removal for an unused driver and some other minor updates - coresight driver updates and additions - MHI driver updates - comedi driver updates and fixes - extcon driver updates - interconnect driver additions - eeprom driver updates and fixes - minor UIO driver updates - tiny W1 driver updates But the majority of new code is in the rust bindings and additions, which includes: - misc driver rust binding updates for read/write support, we can now write "normal" misc drivers in rust fully, and the sample driver shows how this can be done. - Initial framework for USB driver rust bindings, which are disabled for now in the build, due to limited support, but coming in through this tree due to dependencies on other rust binding changes that were in here. I'll be enabling these back on in the build in the usb.git tree after -rc1 is out so that developers can continue to work on these in linux-next over the next development cycle. - Android Binder driver implemented in Rust. This is the big one, and was driving a huge majority of the rust binding work over the past years. Right now there are two binder drivers in the kernel, selected only at build time as to which one to use as binder wants to be included in the system at boot time. The binder C maintainers all agreed on this, as eventually, they want the C code to be removed from the tree, but it will take a few releases to get there while both are maintained to ensure that the rust implementation is fully stable and compliant with the existing userspace apis. All of these have been in linux-next for a while" * tag 'char-misc-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (320 commits) rust: usb: keep usb::Device private for now rust: usb: don't retain device context for the interface parent USB: disable rust bindings from the build for now samples: rust: add a USB driver sample rust: usb: add basic USB abstractions coresight: Add label sysfs node support dt-bindings: arm: Add label in the coresight components coresight: tnoc: add new AMBA ID to support Trace Noc V2 coresight: Fix incorrect handling for return value of devm_kzalloc coresight: tpda: fix the logic to setup the element size coresight: trbe: Return NULL pointer for allocation failures coresight: Refactor runtime PM coresight: Make clock sequence consistent coresight: Refactor driver data allocation coresight: Consolidate clock enabling coresight: Avoid enable programming clock duplicately coresight: Appropriately disable trace bus clocks coresight: Appropriately disable programming clocks coresight: etm4x: Support atclk coresight: catu: Support atclk ...

2025-10-01dt-bindings: mfd: twl: Add missing sub-nodes for TWL4030 & TWL603xJihed Chaibi2-94/+273
Update the main TI TWL-family binding to be self-contained and to fix pre-existing validation errors. To ensure future patches are bisectable, child nodes whose bindings are in other patches (audio, keypad, usb, etc.) are now defined using a flexible 'additionalProperties: true' pattern. This removes hard dependencies between the MFD and subsystem bindings. The complete dtbs_check for this binding is clean except for two warnings originating from pre-existing bugs in the OMAP DTS files, for which fixes have already been submitted separately [1][2].

2025-10-01dt-bindings: mfd: Move embedded controllers to own directoryKrzysztof Kozlowski3-672/+0
Move several embedded controller bindings (like ChromeOS EC, Gateworks System Controller and Kontron sl28cpld Board Management) to new subdirectory "embedded-controller" matching their purpose. An embedded controller (EC) is a discrete component that contains a microcontroller (i.e. a small CPU running a small firmware without operating system) mounted into a larger computer system running a fully fledged operating system that needs to utilize the embedded controller as part of its operation. So far the EC bindings were split between "mfd" and "platform" directory. MFD name comes from Linux, not hardware, and "platform" is a bit too generic. Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as preferred for bindings.

2025-07-24dt-bindings: mfd: rk806: Allow to customize PMIC reset modeQuentin Schulz1-0/+21
The RK806 PMIC allows to configure its reset/restart behavior whenever the PMIC is reset either programmatically or via some external pins (e.g. PWRCTRL or RESETB). The following modes exist: - 0; restart PMU, - 1; reset all power off reset registers and force state to switch to ACTIVE mode, - 2; same as mode 1 and also pull RESETB pin down for 5ms, For example, some hardware may require a full restart (mode 0) in order to function properly as regulators are shortly interrupted in this mode. This is the case for RK3588 Jaguar and RK3588 Tiger which have a companion microcontroller running on an independent power supply and monitoring the PMIC power rail to know the state of the main system. When it detects a restart, it resets its own IPs exposed to the main system as if to simulate its own reset. Failing to perform this fake reset of the microcontroller may break things (e.g. watchdog not automatically disabled, buzzer still running until manually disabled, leftover configuration from previous main system state, etc...). Some other systems may be depending on the power rails to not be interrupted even for a small amount of time[1]. This allows to specify how the PMIC should perform on the hardware level and may differ between hardware designs, so a DT property seems warranted. I unfortunately do not see how this could be made generic enough to make it a non-vendor property.

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.

2025-07-01dt-bindings: mfd: adp5585: ease on the required propertiesNuno Sá1-3/+0
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.

Add support for the ROHM BD96802 scalable companion PMIC to the BD96801 core driver - Add support for controlling the BD96802 using the BD96801 regulator driver - Add support to the BD96805, which is almost identical to the BD96801 - Add support to the BD96806, which is similar to the BD96802 Maxim MAX77759: - Add a core driver for the MAX77759 companion PMIC - Add a GPIO driver for the expander functions on the MAX77759 - Add an NVMEM driver to expose the non-volatile memory on the MAX77759 STMicroelectronics STM32MP25: - Add support for the STM32MP25 SoC to the stm32-lptimer - Add support for the STM32MP25 to the clocksource driver, handling new register access requirements - Add support for the STM32MP25 to the PWM driver, enabling up to two PWM outputs Broadcom BCM590xx: - Add support for the BCM59054 PMU - Parse the PMU ID and revision to support behavioral differences between chip revisions - Add regulator support for the BCM59054 Samsung S2MPG10: - Add support for the S2MPG10 PMIC, which communicates via the Samsung ACPM firmware instead of I2C Exynos ACPM: - Improve timeout detection reliability by using ktime APIs instead of a loop counter assumption - Allow PMIC access during late system shutdown by switching to 'udelay()' instead of a sleeping function - Fix an issue where reading command results longer than 8 bytes would fail - Silence non-error '-EPROBE_DEFER' messages during boot to clean up logs Exynos LPASS: - Fix an error handling path by switching to 'devm_regmap_init_mmio()' to prevent resource leaks - Fix a bug where 'exynos_lpass_disable()' was called twice in the remove function - Fix another resource leak in the probe's error path by using 'devm_add_action_or_reset()' Samsung SEC: - Handle the s2dos05, which does not have IRQ support, explicitly to prevent warnings - Fix the core driver to correctly handle errors from 'sec_irq_init()' instead of ignoring them STMPE-SPI: - Correct an undeclared identifier in the 'MODULE_DEVICE_TABLE' macro MAINTAINERS: - Adjust a file path for the Siemens IPC LED drivers entry to fix a broken reference Maxim Drivers: - Correct the spelling of "Electronics" in Samsung copyright headers across multiple files General: - Fix wakeup source memory leaks on device unbind for 88pm886, as3722, max14577, max77541, max77705, max8925, rt5033, and sprd-sc27xx drivers Samsung SEC Drivers: - 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 -
