- New parameterized test features
KUnit parameterized tests supported two primary methods for getting
parameters:
- Defining custom logic within a generate_params() function.
- Using the KUNIT_ARRAY_PARAM() and KUNIT_ARRAY_PARAM_DESC() macros
with a pre-defined static array and passing the created
*_gen_params() to KUNIT_CASE_PARAM().
These methods present limitations when dealing with dynamically
generated parameter arrays, or in scenarios where populating
parameters sequentially via generate_params() is inefficient or
overly complex.
These limitations are fixed with a parameterized test method

all of them being either upgrades or cut-down versions of the older
chips:
- Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation
of high-end workstations and laptops from Apple. Linux has been
working on these for a while but stil requires patches.
- Axis Artpec8 is an Armv8 chip based on Samsung Exynos design,
unlike the earlier Armv7 Artpec6 from the same company that was
part of a separate family of chips.
- NXP i.MX91 is a cut-down version of i.MX93, using only a single
Cortex-A55 core.
- Qualcomm Lemans Auto is a variant of the Lemans SoC that was
originally merged under the sa8775p name, the differences being
mostly the firmware configuration of the platform.
- Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44),
RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial

In total, there are 65 new machines, including:
- Industrial embedded system and single-board computers based on NXP,
Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips.
- Reference boards for the newly added Renesas, Qualcomm, NXP and
Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC
- Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1
chips.
- Several Samsung phones using Qualcomm Snapdragon chips
- Set-top boxes based on Allwinner H313
- Five BMC boards using 32-bit ASpeed SoCs
- Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708

quantities but never made it into products: one STi407 based reference
board, and a Snapdragon 845 based Chromebook.

Pull pin control updates from Linus Walleij:
"We have GPIO awareness in the pin control core and an interesting
AAEON driver.
Core changes:
- Allow pins to be identified/marked as GPIO mode with a special
callback.
The pin controller core is now "aware" if a pin is in GPIO mode if
the callback is implemented in the driver, and can thus be marked
as "strict", i.e. disallowing simultaneous use of a line as GPIO
and another function such as I2C.
This is enabled in the Qualcomm TLMM driver and also implemeted
from day 1 in the new Broadcom STB driver
- Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL
to better describe what the config is doing, as well as making it
more intuitive what shall be returned when reading this property
This is some special pin controller that works as an external
advanced line MUX and amplifier for signals from an Intel SoC. A
cooperative effort with the GPIO maintainer was needed to reach a
solution where we reuse code from the GPIO aggregator/forwarder
driver
- Renesas RZ/T2H and RZ/N2H pin controller support
- Axis ARTPEC-8 subdriver for the Samsung pin controller driver
Improvements:
- Output enable (OEN) support in the Renesas RZG2L driver
- Properly support bias pull up/down in the pinctrl-single driver
- Move over all GPIO portions using generic MMIO GPIO to the new
generic GPIO chip management which has a nice and separate API
- Proper DT bindings for some older Broadcom SoCs
- External GPIO (EGPIO) support in the Qualcomm SM8250

- Dropped the now unused Samsung S3C24xx drivers"

include new drivers for Loongson's Security Engine, RNG and TPM, new
drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs.
The rest of the set provides a return value check fix and a
refactoring to use a more modern GPIO API for the VEXPRESS sysreg
driver, the removal of a deprecated IRQ ACK function from the MC13xxx
RTC driver and a new DT binding for the aforementioned TI BQ257xx
charger.
New Support & Features:
- Add a suite of drivers for the Loongson Security Engine, including
the core controller, a Random Number Generator (RNG) and Trusted
Platform Module (TPM) support.
- Introduce support for the TI TPS6594 PMIC's power button, including
the input driver, MFD cell registration, and a system power-off
handler.
- Add comprehensive support for the TI BQ257xx series of charger ICs,
including the core MFD driver and a power supply driver for the
charger functionality.
Improvements & Fixes:
- Check the return value of devm_gpiochip_add_data() in the VEXPRESS
sysreg driver to prevent potential silent failures.
Cleanups & Refactoring:
- Add a MAINTAINERS entry for the new Loongson Security Engine
drivers.
- Convert the VEXPRESS sysreg driver to use the modern generic GPIO
chip API.
Removals:
- Remove the deprecated and unused mc13xxx_irq_ack() function from
the MC13xxx RTC, input and touchscreen drivers.
Device Tree Bindings Updates:
- Add device tree bindings for the TI BQ25703A charger"

bit of work done on them.
Possibly the most interesting thing is the VirtIO driver, this is
apparently useful for some automotive applications which want to keep
as small and robust a host system as they can, moving less critical
functionality into guests.
- James Clark has done some substantial updates on the Freescale DSPI
driver, porting in code from the BSP and building onm top of that
to fix some bugs and increase performance
- Jonas Gorski has fixed the issues with handling multple chip
selects, making things more robust and scalable
- Support for higher performance modes in the NXP FSPI driver from
Haibo Chen

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"

dt-bindings: mfd: twl: Add missing sub-nodes for TWL4030 & TWL603x
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,

it acts as an interrupt controller. There's 4 interrupt sources in

mfd: cs42l43: Move IRQ enable/disable to encompass force suspend
As pm_runtime_force_suspend() will force the device state to suspend,
the driver needs to ensure no IRQ handlers are currently running. If not
those handlers may find they are now running on suspended hardware
despite holding a PM runtime reference. disable_irq() will sync any
currently running handlers, so move the IRQ disabling to cover the whole
of the forced suspend state to avoid such race conditions.
mfd: ls2kbmc: Add Loongson-2K BMC reset function support
Since the display is a sub-function of the Loongson-2K BMC, when the
BMC reset, the entire BMC PCIe is disconnected, including the display
which is interrupted.
Quick overview of the entire LS2K BMC reset process:
There are two types of reset methods: soft reset (BMC-initiated reboot
of IPMI reset command) and BMC watchdog reset (watchdog timeout).
First, regardless of the method, an interrupt is generated (PCIe interrupt
for soft reset/GPIO interrupt for watchdog reset);
Second, during the interrupt process, the system enters bmc_reset_work,
clears the bus/IO/mem resources of the LS7A PCI-E bridge, waits for the BMC
reset to begin, then restores the parent device's PCI configuration space,
waits for the BMC reset to complete, and finally restores the BMC PCI
configuration space.

An embedded controller (EC) is a discrete component that contains a
microcontroller (i.e. a small CPU running a small firmware without

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"

mfd: da9063: Split chip variant reading in two bus transactions
We observed the initial probe of the da9063 failing in
da9063_get_device_type in about 30% of boots on a Xilinx ZynqMP based
board. The problem originates in da9063_i2c_blockreg_read, which uses
a single bus transaction to turn the register page and then read a
register. On the bus, this should translate to a write to register 0,
followed by a read to the target register, separated by a repeated
start. However, we found that after the write to register 0, the
controller sometimes continues directly with the register address of
the read request, without sending the chip address or a repeated start
in between, which makes the read request invalid.
To fix this, separate turning the page and reading the register into
two separate transactions. This brings the initialization code in line
with the rest of the driver, which uses register maps (which to my
knowledge do not use repeated starts after turning the page). This has
been included in our kernel for several months and was recently
included in a shipped product. For us, it reliably fixes the issue,
and we have not observed any new issues.
While the underlying problem is probably with the i2c controller or
its driver, I still propose a change here in the interest of
robustness: First, I'm not sure this issue can be fixed on the
controller side, since there are other issues related to repeated
start which can't (AR# 60695, AR# 61664). Second, similar problems
might exist with other controllers.

Pull timer core updates from Thomas Gleixner:
- Address the inconsistent shutdown sequence of per CPU clockevents on
CPU hotplug, which only removed it from the core but failed to invoke
the actual device driver shutdown callback. This kept the timer
active, which prevented power savings and caused pointless noise in
virtualization.
- Encapsulate the open coded access to the hrtimer clock base, which is
a private implementation detail, so that the implementation can be
changed without breaking a lot of usage sites.
- Enhance the debug output of the clocksource watchdog to provide
better information for analysis.
- The usual set of cleanups and enhancements all over the place

Pull irq chip driver updates from Thomas Gleixner:
- Use the startup/shutdown callbacks for the PCI/MSI per device
interrupt domains.
This allows us to initialize the RISCV PLIC interrupt hierarchy
correctly and provides a mechanism to decouple the masking and
unmasking during run-time from the expensive PCI mask and unmask when
the underlying MSI provider implementation allows the interrupt to be
masked.
- Initialize the RISCV PLIC MSI interrupt hierarchy correctly so that
the affinity assignment works correctly by switching it over to the
startup/shutdown scheme
- Allow MSI providers to opt out from masking a PCI/MSI interrupt at
the PCI device during operation when the provider can mask the
interrupt at the underlying interrupt chip. This reduces the overhead
in scenarios where disable_irq()/enable_irq() is utilized frequently
by a driver.
The PCI/MSI device level [un]masking is only required on startup and
shutdown in this case.
- Remove the conditional mask/unmask logic in the PCI/MSI layer as this
is now handled unconditionally.
- Replace the hardcoded interrupt routing in the Loongson EIOINTC
interrupt driver to respect the firmware settings and spread them out
to different CPU interrupt inputs so that the demultiplexing handler
only needs to read only a single 64-bit status register instead of
four, which significantly reduces the overhead in VMs as the status
register access causes a VM exit.
- Add support for the new AST2700 SCU interrupt controllers
- Use the legacy interrupt domain setup for the Loongson PCH-LPC
interrupt controller, which resembles the x86 legacy PIC setup and
has the same hardcoded legacy requirements.
- The usual set of cleanups, fixes and improvements all over the place

Pull irq core updates from Thomas Gleixner:
"A set of updates for the interrupt core subsystem:
- Introduce irq_chip_[startup|shutdown]_parent() to prepare for
addressing a few short comings in the PCI/MSI interrupt subsystem.
It allows to utilize the interrupt chip startup/shutdown callbacks
for initializing the interrupt chip hierarchy properly on certain
RISCV implementations and provides a mechanism to reduce the
overhead of masking and unmasking PCI/MSI interrupts during
operation when the underlying MSI provider can mask the interrupt.
The actual usage comes with the interrupt driver pull request.
- Add generic error handling for devm_request_*_irq()
This allows to remove the zoo of random error printk's all over the
usage sites.
- Add a mechanism to warn about long-running interrupt handlers
Long running interrupt handlers can introduce latencies and
tracking them down is a tedious task. The tracking has to be
enabled with a threshold on the kernel command line and utilizes a
static branch to remove the overhead when disabled.
- Update and extend the selftests which validate the CPU hotplug
interrupt migration logic
- Allow dropping the per CPU softirq lock on PREEMPT_RT kernels,
which causes contention and latencies all over the place.
The serialization requirements have been pushed down into the
actual affected usage sites already.
- The usual small cleanups and improvements"
