Merge tag 'char-misc-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2025-10-04T23:26:32+00:00

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 ...

dt-bindings: eeprom: at24: Add compatible for Giantec GT24C256C

2025-09-11T13:19:02+00:00

The gt24c256c is another 24c256 compatible EEPROM, and does not follow the generic name matching, so add a separate compatible for it. This ensures accurate device-tree representation and enables proper kernel support for systems using this part.
