i2c-for-6.13-rc1
i2c-core (Wolfram)
- drivers can now use a GPIO as a side channel for SMBus Alerts
using a generic binding
- regular stuff like mem leak fix, Makefile maintenance...
i2c-host updates (Andi)
Major Improvements and Refactoring:
- All controllers using the 'remove_new' callback have been
reverted to use the 'remove' callback.
- Intel SCH controller underwent significant refactoring,
this brings love and a modern look to the driver.
- PIIX4 driver refactored to enable usage by other drivers
(e.g., AMD ASF).
- iMX/MXC improved message handling to reduce protocol overhead:
Refactored DMA/non-DMA read/write and bus polling mechanisms
to achieve this.
- ACPI documentation for PIIX4.
New Features:
- i2c-cadence added support for atomic transfers.
- Qualcomm CII added support for a 32MHz serial engine clock.
Deprecated Features:
- Dropped outdated support for AMD756 S4882 and NFORCE2 S4985. If
somebody misses this, Jean will rewrite support using the proper
i2c mux framework.
New Hardware Support:
- Added support for:
- Intel Panther Lake (new ID)
- AMD ASF (new driver)
- S32G2/S32G3 SoCs (new ID)
- Realtek RTL I2C Controller (new driver)

soc: driver updates for 6.12
Nothing particular important in the SoC driver updates, just the usual
improvements to for drivers/soc and a couple of subsystems that don't
fit anywhere else:
- The largest set of updates is for Qualcomm SoC drivers, extending the
set of supported features for additional SoCs in the QSEECOM, LLCC
and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip
sparx5 and amlogic reset drivers to support additional chips,
plus a few minor updates on other platforms
- The SCMI firmware interface driver gains support for two protocol
extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
and a few bugfixes
- The Hisilicon Kunpeng HCCS driver gains support for configuring
lanes through sysfs
Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
and drivers/memory, including changing back the .remove_new callback
to .remove, as well as a few other updates for freescale (powerpc)
soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

Reset controller updates for v6.13
* Split the Amlogic reset-meson driver into platform and auxiliary bus drivers. Add support for the reset controller in the G12 and SM1 audio clock controllers. * Replace the list of boolean parameters to the internal reset_control_get functions with an enum reset_flags bitfield, to make the code more self-descriptive. * Add devres helpers to request pre-deasserted (and automatically re-asserting during cleanup) reset controls. This allows reducing boilerplate in drivers that deassert resets for the lifetime of a device. * Use the new auto-deasserting devres helpers in reset-uniphier-glue as an example. * Add support for the LAN966x PCI device in drivers/misc, as a dependency for the following reset-microchip-sparx5 patches. * Add support for being used on the LAN966x PCI device to the reset-microchip-sparx5 driver.

misc: lan966x_pci: Fix dtc warn 'Missing interrupt-parent'
dtc generates the following warning when building the LAN966x devicetree
overlay (lan966x_pci.dtso):
Warning (interrupts_property): /fragment@0/__overlay__/pci-ep-bus@0/oic@e00c0120: Missing interrupt-parent
The oic interrupt parent is the PCI device itself. The PCI device node
is the node on which the dtbo will be applied and this node already has
properties needed.
In order to remove the warning, add the missing properties in the
overlay fragment node. Properties in this node will not be added when
the overlay is applied (which is what we expect) but makes dtc happy.

mei: use kvmalloc for read buffer
Read buffer is allocated according to max message size, reported by
the firmware and may reach 64K in systems with pxp client.
Contiguous 64k allocation may fail under memory pressure.
Read buffer is used as in-driver message storage and not required
to be contiguous.
Use kvmalloc to allow kernel to allocate non-contiguous memory.

misc: Add support for LAN966x PCI device
Add a PCI driver that handles the LAN966x PCI device using a device-tree overlay. This overlay is applied to the PCI device DT node and allows to describe components that are present in the device. The memory from the device-tree is remapped to the BAR memory thanks to "ranges" properties computed at runtime by the PCI core during the PCI enumeration. The PCI device itself acts as an interrupt controller and is used as the parent of the internal LAN966x interrupt controller to route the interrupts to the assigned PCI INTx interrupt.

eeprom: at24: add ST M24256E Additional Write lockable page support
The ST M24256E behaves as a regular M24C256, except for the E variant which uses up another I2C address for Additional Write lockable page. This page is 64 Bytes long and can contain additional data. Add entry for it, so users can describe that page in DT. Note that users still have to describe the main M24C256 area separately as that is on separate I2C address from this page. Unlike M24C32-D and M24C64-D, this part is specifically ST and does not have any comparable M24* counterparts from other vendors, hence the st, vendor prefix. Furthermore, the part name is M24256E without C between the 24 and 256, this is not a typo. Finally, there is M24C256-D part, which does contain 32 Bytes long Additional Write lockable page, which is a different part and not supported by this patch.

Char/Misc/IIO fixes for 6.12-rc4
Here are a number of small char/misc/iio driver fixes for 6.12-rc4.
Included in here are the following:
- loads of small iio driver fixes for reported problems
- parport driver out-of-bounds fix
- Kconfig description and MAINTAINERS file updates
All of these, except for the Kconfig and MAINTAINERS file updates have

Char/Misc and other driver changes for 6.12-rc1
Here is the "big" set of char/misc and other driver subsystem changes for 6.12-rc1. Sorry for the delay, conference travel for the past two weeks has this and my other pull requests showing up real late in the cycle. Lots of changes in here, primarily dominated by the usual IIO driver updates and additions, but there are also small driver subsystem updates all over the place. Included in here are: - lots and lots of new IIO drivers and updates to existing ones - interconnect subsystem updates and new drivers - nvmem subsystem updates and new drivers - mhi driver updates - power supply subsystem updates - kobj_type const work for many different small subsystems - comedi driver fix - coresight subsystem and driver updates - fpga subsystem improvements - slimbus fixups - binder new feature addition for "frozen" notifications - lots and lots of other small driver updates and cleanups All of these have been in linux-next for a long time with no reported problems.

Many singleton patches - please see the various changelogs for details.
Quite a lot of nilfs2 work this time around.
Notable patch series in this pull request are:
"mul_u64_u64_div_u64: new implementation" by Nicolas Pitre, with
assistance from Uwe Kleine-König. Reimplement mul_u64_u64_div_u64() to

Collin. Miscellaneous maintenance and kinor feature work to the xz
decompressor.
"Fix some GDB command error and add some GDB commands" from Kuan-Ying Lee.
Fixes and enhancements to the gdb scripts.
"treewide: add missing MODULE_DESCRIPTION() macros" from Jeff Johnson.
Adds lots of MODULE_DESCRIPTIONs, thus fixing lots of warnings about this.
"nilfs2: add support for some common ioctls" from Ryusuke Konishi. Adds
various commonly-available ioctls to nilfs2.
"This series fixes a number of formatting issues in kernel doc comments"
from Ryusuke Konishi does that.
"nilfs2: prevent unexpected ENOENT propagation" from Ryusuke Konishi. Fix
issues where -ENOENT was being unintentionally and inappropriately
returned to userspace.
"nilfs2: assorted cleanups" from Huang Xiaojia.
"nilfs2: fix potential issues with empty b-tree nodes" from Ryusuke
Konishi fixes some issues which can occur on corrupted nilfs2 filesystems.

rpmb: fix error path in rpmb_dev_register()
Until this patch was rpmb_dev_register() always freeing rdev in the error
path. However, past device_register() it must not do that since the memory
is now managed by the device even if it failed to register properly. So fix
this by doing a put_device() before returning the error code.
Fixes the smatch warning:

VMCI: Fix use-after-free when removing resource in vmci_resource_remove()
When removing a resource from vmci_resource_table in
vmci_resource_remove(), the search is performed using the resource
handle by comparing context and resource fields.
It is possible though to create two resources with different types
but same handle (same context and resource fields).
When trying to remove one of the resources, vmci_resource_remove()
may not remove the intended one, but the object will still be freed
as in the case of the datagram type in vmci_datagram_destroy_handle().
vmci_resource_table will still hold a pointer to this freed resource
leading to a use-after-free vulnerability.

fault-inject: improve build for CONFIG_FAULT_INJECTION=n
The fault-inject.h users across the kernel need to add a lot of #ifdef
CONFIG_FAULT_INJECTION to cater for shortcomings in the header. Make
fault-inject.h self-contained for CONFIG_FAULT_INJECTION=n, and add stubs
for DECLARE_FAULT_ATTR(), setup_fault_attr(), should_fail_ex(), and
should_fail() to allow removal of conditional compilation.
[akpm@linux-foundation.org: repair fallout from no longer including debugfs.h into fault-inject.h]
[akpm@linux-foundation.org: fix drivers/misc/xilinx_tmr_inject.c]
[akpm@linux-foundation.org: Add debugfs.h inclusion to more files, per Stephen]

rpmb: add Replay Protected Memory Block (RPMB) subsystem
A number of storage technologies support a specialised hardware partition designed to be resistant to replay attacks. The underlying HW protocols differ but the operations are common. The RPMB partition cannot be accessed via standard block layer, but by a set of specific RPMB commands. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage. The initial aim of this patch is to provide a simple RPMB driver interface which can be accessed by the optee driver to facilitate early RPMB access to OP-TEE OS (secure OS) during the boot time. A TEE device driver can claim the RPMB interface, for example, via rpmb_interface_register() or rpmb_dev_find_device(). The RPMB driver provides a callback to route RPMB frames to the RPMB device accessible via rpmb_route_frames(). The detailed operation of implementing the access is left to the TEE device driver itself.

kgdbts: fix hw_access_break_test
The test for access watchpoints (hw_access_break_test) was broken (always failed) because the compiler optimized out the write to the static helper variable (hw_break_val2), as it is never read anywhere. This resulted in the target variable (hw_break_val) not being accessed and thus the breakpoint not being triggered. Remove the helper variable (hw_break_val2), and use READ_ONCE to force reading the target variable (hw_break_val).

refcount: Report UAF for refcount_sub_and_test(0) when counter==0
When a reference counter is at zero and refcount_sub_and_test() is invoked to subtract zero, the function accepts this request without any warning and returns true. This behavior does not seem ideal because the counter being already at zero indicates a use-after-free. Furthermore, returning true by refcount_sub_and_test() in this case potentially results in a double-free done by its caller. Modify the underlying function __refcount_sub_and_test() to warn about this case as a use-after-free and have it return false to avoid the potential double-free.

The CXL driver has its own custom implementations of typed DT property accessors. Replace the custom property accessor functions with the common DT property functions.

eeprom: ee1004: Fix locking issues in ee1004_probe()
Currently, the devres-based management of ee1004_bus_data has
several issues when it comes to locking:
1. It does not call mutex_unlock() before returning an error.
2. When encountering an error, it deadlocks when trying to recursively
lock a mutex.
Fix this by moving the mutex-protected bus data initialization into
a separate function so that devm_add_action_or_reset() is called
without the mutex being held.

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

The I2C core gains documentation updates for the testunit, a cleanup
regarding unneeded 'driver_data' and more sanity checks in the char
device.
For the host drivers, this release includes significant updates, with
the primary change being the renaming from "master/slave" to
"controller/target" to adhere to I2C v7 and SMBus 3.2 standards.
New Support:
- Added support for Intel Arrow Lake-H.
- Added I2C support in the Arioha SoC by linking the Mediatek
I2C controller.
Cleanups:
- Added the MODULE_DESCRIPTION() macro, resolving a modpost
warning in the ALi 1563 Southbridge driver.
- Constified the regmap_config declaration in the i2c-designware
driver.
- Improved the coding style in the Renesas R-Car driver by
removing unnecessary semicolons after brackets.
General improvements:
- In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with
RUNTIME_PM_OPS to enable waking up the controller during
suspend() before suspend_noirq() kicks in.
- Improved logging in the Xilinx driver.
- Added a warning (WARN()) in the Renesas R-Car driver for
spurious interrupts.
DTS Changes:
- Removed address-cell and size-cell from the Atmel at91sam,
nVidia Tegra 20, and Samsung S3c2410 devices.
- Fixed Texas Instruments OMAP4 I2C controller to comply with
the i2c-controller.yaml schema.
- Improved indentation in DTS examples for several I2C devices.
- Converted the NXP LPC1788 binding to the dt-schema.
- Added documentation for the compatible string
thead,th1520-i2c.
- Added the "power-domains" property for the Meson I2C driver.
AT24 EEPROM driver changes:
- add support for two new Microchip models
- document even more new models in DT bindings (those use fallback
compatibles so no code changes)
