Merge tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2026-08-25T16:38:50+00:00

Pull char/misc/IIO/etc driver updates from Greg KH: "Here is the big set of char, misc, iio, counter, fpga, and other small driver subsystems for 7.3-rc1. Overall, due to some driver removals we only added a bit more code than removed, which was a nice change. Highlights in this merge request are: - Loads of IIO driver updates and additions - binder driver updates (more on that below...) - Removal of the SGI XP and GRU drivers as they are not used anymore and turn out to be pretty insecure overall - Removal of the obsolete ibmasm driver as it's not being used anymore - Coresight driver updates and additions - Mei driver udpates - Counter driver updates - FPGA driver updates - ICC driver updates - lots and lots of other tiny driver updates to resolve reported issues All of these have been in linux-next for a while" * tag 'char-misc-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (513 commits) iio: chemical: atlas-sensor: use iio_trigger_poll_nested() to fix remove UAF iio: adc: pac1921: fix wrong channel used in trigger handler read iio: light: gp2ap002: re-enable irq if runtime suspend fails iio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes iio: light: apds9306: fix PM reference leak in apds9306_read_data() iio: gyro: mpu3050: fix sign of raw angular velocity readings iio: srf04: fix pm_runtime handling on probe error path iio: adc: ad4080: configure backend data size iio: adc: adi-axi-adc: add data size support for AD408X backend iio: chemical: atlas-sensor: fix PM reference leak in buffer postenable iio: dac: ad5446: fix OF module device table iio: light: opt4001: Fix reversed GENMASK() arguments in fault count mask iio: light: opt4001: Reject integration times with a non-zero seconds part iio: light: opt4001: Fix incompatible pointer type passed to div_u64_rem() iio: light: opt4001: Fix power down clearing bits of the wrong register iio: light: opt4060: Fix incorrect register name in threshold read error message iio: light: opt4060: Fix pointer type passed to div_u64_rem() iio: light: opt4060: Reject integration times with a non-zero seconds part iio: light: ltrf216a: fix runtime PM reference leak in error path iio: pressure: dps310: fix NULL pointer dereference on ACPI probe ...

hwmon: (emc1403) Drop hysteresis for low limit temperature

2026-08-16T21:40:33+00:00

Remove the hysteresis for low temperature limit, in hardware the hysteresis is applied only to the maxim limit and the critical limit temperature.

hwmon: (asus_rog_ryujin) Add ROG Ryujin III White Edition

2026-08-14T18:21:27+00:00

The ROG Ryujin III White Edition uses the same report layout as the other supported Ryujin III variants. Add its USB device ID and list it in the driver documentation. The device was tested with the driver on the author's hardware.

hwmon: (asus_rog_ryujin) Add ROG Ryujin III support

2026-08-14T18:20:54+00:00

The ROG Ryujin III uses different report offsets and a different cooler-duty channel from the Ryujin II. It also lacks the separate external fan controller supplied with the older model. Add model data and USB IDs for the Extreme and EVA Edition variants. Skip controller commands and hide the unavailable controller hwmon channels for these devices. Update the driver documentation, Kconfig text, and module description accordingly.

2026-08-10T15:59:43+00:00

The ROG STRIX Z390-E GAMING and Z390-F GAMING are essentially the same board apart from the E's onboard WiFi, so they share the same EC sensor layout.

hwmon: (pmbus/mpq8646) Gate the writes

2026-08-10T15:59:43+00:00

The write cases of debugfs entries are provisioning and bench helpers. By designs the MPQ8646 powers the CPU core rail, so a wrong write can brown out the board or persist a bad setpoint into finite-cycle NVM. Said differently: some wrong register writes can and likely will physically damage or destroy the chip and/or the board. To be safe, it is disabled by default behind a CONFIG_SENSORS_MPQ8646_DEBUG_UNSAFE and we print an explicit warning banner at probe time when they are built in.
