Pull i3c fixes from Alexandre Belloni: "This introduces the I3C_OR_I2C symbol which is not a fix per se but is affecting multiple subsystems so it is included to ease synchronization. Apart from that, Adrian is mostly fixing the mipi-i3c-hci driver DMA handling, and I took the opportunity to add two fixes for the dw-i3c driver. Subsystem: - simplify combined i3c/i2c dependencies Drivers: - dw: handle 2C properly, fix possible race condition - mipi-i3c-hci: many DMA related fixes" * tag 'i3c/fixes-for-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux: i3c: dw-i3c-master: Set SIR_REJECT in DAT on device attach and reattach i3c: master: dw-i3c: Fix missing of_node for virtual I2C adapter i3c: mipi-i3c-hci: Fallback to software reset when bus disable fails i3c: mipi-i3c-hci: Fix handling of shared IRQs during early initialization i3c: mipi-i3c-hci: Fix race in DMA error handling in interrupt context i3c: mipi-i3c-hci: Consolidate common xfer processing logic i3c: mipi-i3c-hci: Restart DMA ring correctly after dequeue abort i3c: mipi-i3c-hci: Add missing TID field to no-op command descriptor i3c: mipi-i3c-hci: Correct RING_CTRL_ABORT handling in DMA dequeue i3c: mipi-i3c-hci: Fix race between DMA ring dequeue and interrupt handler i3c: mipi-i3c-hci: Fix race in DMA ring dequeue i3c: mipi-i3c-hci: Fix race in DMA ring enqueue for parallel xfers i3c: mipi-i3c-hci: Consolidate spinlocks i3c: mipi-i3c-hci: Factor out DMA mapping from queuing path i3c: mipi-i3c-hci: Fix Hot-Join NACK i3c: mipi-i3c-hci: Use ETIMEDOUT instead of ETIME for timeout errors i3c: simplify combined i3c/i2c dependencies

i3c: simplify combined i3c/i2c dependencies

2026-02-27T15:33:07+00:00

All combined i2c/i3c drivers appear to suffer from the same link time problem when CONFIG_I3C is set to 'm': arm-linux-gnueabi-ld: drivers/iio/magnetometer/mmc5633.o: in function `mmc5633_i3c_driver_init': mmc5633.c:(.init.text+0x30): undefined reference to `i3c_driver_register_with_owner' This was previously fixed every time by marking individual drivers as 'depends on I2C; depends on I3C || !I3C', but this gets tedious and is somewhat confusing. Add a Kconfig symbol 'I3C_OR_I2C' to help replace those dependencies, and use this in all the existing drivers that had already fixed it as well as the new mmc5633 driver.

hwmon: (tmp108) Add support for P3T1035 and P3T2030

2026-01-31T15:38:33+00:00

Add support for the P3T1035 & P3T2030 temperature sensor. While mostly compatible with the TMP108, P3T1035 uses an 8-bit configuration register instead of the 16-bit layout used by TMP108. Updated driver to handle this difference during configuration read/write.

hwmon: Add Apple Silicon SMC hwmon driver

2025-11-19T02:46:21+00:00

The System Management Controller on Apple Silicon devices is responsible for integrating and exposing the data reported by the vast array of hardware monitoring sensors present on these devices. It is also responsible for fan control, and allows users to manually set fan speeds if they so desire. Add a hwmon driver to expose current, power, temperature, and voltage monitoring sensors, as well as fan speed monitoring and control via the SMC on Apple Silicon devices. The SMC firmware has no consistency between devices, even when they share an SoC. The FourCC keys used to access sensors are almost random. An M1 Mac mini will have different FourCCs for its CPU core temperature sensors to an M1 MacBook Pro, for example. For this reason, the valid sensors for a given device are specified in a child of the SMC Devicetree node. The driver uses this information to determine which sensors to make available at runtime.

hwmon: Add TSC1641 I2C power monitor driver

2025-11-12T20:09:08+00:00

Add a driver for the ST Microelectronics TSC1641 16-bit high-precision power monitor. The driver supports reading bus voltage, current, power, and temperature. Sysfs attributes are exposed for shunt resistor and update interval. The driver integrates with the hwmon subsystem and supports optional ALERT pin polarity configuration.

Pull gpio updates from Bartosz Golaszewski: "There are two new drivers and support for more models in existing ones. The generic GPIO API has been reworked and all users converted which allowed us to move the fields specific to the generic GPIO implementation out of the high-level struct gpio_chip into its own structure that wraps the gpio_chip. Other than that, there's nothing too exciting. Mostly minor tweaks and fixes all over the place, some refactoring and some small new features in helper modules. GPIO core: - add support for sparse pin ranges to the glue between GPIO and pinctrl - use a common prefix across all GPIO descriptor flags for improved namespacing New drivers: - add new GPIO driver for the Nuvoton NCT6694 - add new GPIO driver for MAX7360 Driver improvements: - add support for Tegra 256 to the gpio-tegra186 driver - add support for Loongson-2K0300 to the gpio-loongson-64bit driver - refactor the gpio-aggregator module to expose its GPIO forwarder API to other in-kernel users (to enable merging of a new pinctrl driver that uses it) - convert all remaining drivers to using the modernized generic GPIO chip API and remove the old interface - stop displaying global GPIO numbers in debugfs output of controller drivers - extend the gpio-regmap helper with a new config option and improve its support for GPIO interrupts - remove redundant fast_io parameter from regmap configs in GPIO drivers that already use MMIO regmaps which imply it - add support for a new model in gpio-mmio: ixp4xx expansion bus - order includes alphabetically in a few drivers for better readability - use generic device properties where applicable - use devm_mutex_init() where applicable - extend build coverage of drivers by enabling more to be compiled with COMPILE_TEST enabled - allow building gpio-stmpe as a module - use dev_err_probe() where it makes sense in drivers Late driver fixes: - fix setting GPIO direction to output in gpio-mpfs Documentation: - document the usage of software nodes with GPIO chips Device-tree bindings: - Add DT bindings documents for new hardware: Tegra256, MAX7360 - Document a new model in Loongson bindings: LS2K0300 - Document a new model using the generic GPIO binding: IXP4xx - Convert the DT binding for fsl,mxs-pinctrl to YAML - fix the schema ID in the "trivial" GPIO schema - describe GPIO hogs in the generic GPIO binding" * tag 'gpio-updates-for-v6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (122 commits) gpio: mpfs: fix setting gpio direction to output gpio: generic: move GPIO_GENERIC_ flags to the correct header gpio: generic: rename BGPIOF_ flags to GPIO_GENERIC_ gpio: nomadik: fix the debugfs helper stub MAINTAINERS: Add entry on MAX7360 driver input: misc: Add support for MAX7360 rotary input: keyboard: Add support for MAX7360 keypad gpio: max7360: Add MAX7360 gpio support gpio: regmap: Allow to provide init_valid_mask callback gpio: regmap: Allow to allocate regmap-irq device pwm: max7360: Add MAX7360 PWM support pinctrl: Add MAX7360 pinctrl driver mfd: Add max7360 support dt-bindings: mfd: gpio: Add MAX7360 rtc: Add Nuvoton NCT6694 RTC support hwmon: Add Nuvoton NCT6694 HWMON support watchdog: Add Nuvoton NCT6694 WDT support can: Add Nuvoton NCT6694 CANFD support i2c: Add Nuvoton NCT6694 I2C support gpio: Add Nuvoton NCT6694 GPIO support ...
