1. Basic support for SCMI v3.2 pincontrol protocol
SCMI v3.2 introduces pincontrol protocol which is intended for
controlling pins and their configuration. The pin control protocol
provides commands to:
- List the pins, groups of pins, available functions, and their
association with each other.
- Set the parameter configuration and multiplexing of the pins or
groups of pins
- Optionally request exclusive access to a pin or group of pins.
- Optionally configure the permissions of an agent to access a pin
or group of pins.
These changes adds basic support for the same in the SCMI core layer
and an implementation of the generic scmi-pinctrl driver with associated
DT bindings.
2. Framework support for multiple vendors custom protocols
With the fixed space for vendor protocols, the possibility of having
multiple vendors implementing distinct SCMI vendor protocols with
the same overlapping protocol number is very high and with the need
to support them all in a single kernel image or a module is also high.
In order to implement the same we assume:
- vendor protocols has to be tagged at build time with a vendor_id
- vendor protocols could also optionally be tagged at build time with
sub_vendor_id and implementation version
At the initialisation all the built vendor protocols are registered
with the SCMI core using a key derived from the above tags
3. Logging and tracing improvements
This includes using dev_err_probe() to bail out from probe, adding
message dump traces for bad and unexpected replies and widening of
the tag buffer in trace_scmi_dump_msg to allow diverse tag names
4. Miscellaneous updates or improvements
This includes adding the accessor function get_max_msg_size() used
in pinctl protocol, updation of dt-bindings examples for protocol@13
to promote new bindings and simplification of scmi_devm_notifier_unregister

This introduces a TEE driver for Trusted Services [1].
Trusted Services is a TrustedFirmware.org project that provides a
framework for developing and deploying device Root of Trust services in
FF-A [2] Secure Partitions. The project hosts the reference
implementation of Arm Platform Security Architecture [3] for Arm
A-profile devices.
The FF-A Secure Partitions are accessible through the FF-A driver in
Linux. However, the FF-A driver doesn't have a user space interface so
user space clients currently cannot access Trusted Services. The goal of
this TEE driver is to bridge this gap and make Trusted Services
functionality accessible from user space.

The Qualcomm SCM driver initialization order is improved, to avoid any
potential for a client to find a half-initialized SCM instance.
The handling of download mode bits is updated to not attempt
QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is
specified, and that path is changed to perform a read-modify-write to
avoid updating unrelated bits. Error handling is corrected in the
peripheral authentication service (PAS) functions, to release
interconnect bandwidth votes in the case of an error. An unwanted error
print on allocation error is also removed from this code path.
The QSEECOM allow list is marked __maybe_unused to avoid build warnings
when built with !OF. The error handling related to the interconnect API
is cleaned up to avoid handling the impossible IS_ERR() condition.
initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent
drivers like regulators, interconnects and clocks are registered at this
level.
Another attempt is made to remove the strncpy() usage in cmd-db, this
time with strtomem_pad() which has the correct characteristics.
The bwmon regmap cache is changed to maple tree.
After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers,
the intention of not having them automatically load is documented.
Operations on the pmic_glink client list is put under mutual exclusion,
to avoid races when clients are being registered. pmic_glink client
registered after the firmware notification arrived was not informed that
the firmware was up, this is resolved.
More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver.
Checks for in-flight regulator requests in the RPMh RSC driver is
improved to deal with the fact that these occupy multiple registers, so
it's insufficient to just to direct address comparison.
The socinfo drivers learns about X1 Elite and SMB2360 PMIC.
The maintainers entry is split between the linux-arm-msm list and
subset that is maintained in the qcom-soc tree, to avoid some confusion
about maintainership.

Highlights:
---------
Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x
platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers
register to the framework to offer firewall services such as access
granting.
This series of patches is a new approach on the previous STM32 system
bus, history is available here:
https://lore.kernel.org/lkml/20230127164040.1047583/
The need for such framework arises from the fact that there are now
multiple hardware firewalls implemented across multiple products.
Drivers are shared between different products, using the same code.
When it comes to firewalls, the purpose mostly stays the same: Protect
hardware resources. But the implementation differs, and there are
multiple types of firewalls: peripheral, memory, ...
Some hardware firewall controllers such as the RIFSC implemented on
STM32MP2x platforms may require to take ownership of a resource before
being able to use it, hence the requirement for firewall services to
take/release the ownership of such resources.
On the other hand, hardware firewall configurations are becoming
more and more complex. These mecanisms prevent platform crashes
or other firewall-related incoveniences by denying access to some
resources.
The stm32 firewall framework offers an API that is defined in
firewall controllers drivers to best fit the specificity of each
firewall.
For every peripherals protected by either the ETZPC or the RIFSC, the
firewall framework checks the firewall controlelr registers to see if
the peripheral's access is granted to the Linux kernel. If not, the
peripheral is configured as secure, the node is marked populated,
so that the driver is not probed for that device.
The firewall framework relies on the access-controller device tree
binding. It is used by peripherals to reference a domain access
controller. In this case a firewall controller. The bus uses the ID
referenced by the access-controller property to know where to look
in the firewall to get the security configuration for the peripheral.
This allows a device tree description rather than a hardcoded peripheral
table in the bus driver.
The STM32 ETZPC device is responsible for filtering accesses based on
security level, or co-processor isolation for any resource connected
to it.
The RIFSC is responsible for filtering accesses based on Compartment
ID / security level / privilege level for any resource connected to
it.

STM32 Firewall bus for v6.10, round 1
Highlights:
---------
Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x
platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers
register to the framework to offer firewall services such as access
granting.
This series of patches is a new approach on the previous STM32 system
bus, history is available here:
https://lore.kernel.org/lkml/20230127164040.1047583/
The need for such framework arises from the fact that there are now
multiple hardware firewalls implemented across multiple products.
Drivers are shared between different products, using the same code.
When it comes to firewalls, the purpose mostly stays the same: Protect
hardware resources. But the implementation differs, and there are
multiple types of firewalls: peripheral, memory, ...
Some hardware firewall controllers such as the RIFSC implemented on
STM32MP2x platforms may require to take ownership of a resource before
being able to use it, hence the requirement for firewall services to
take/release the ownership of such resources.
On the other hand, hardware firewall configurations are becoming
more and more complex. These mecanisms prevent platform crashes
or other firewall-related incoveniences by denying access to some
resources.
The stm32 firewall framework offers an API that is defined in
firewall controllers drivers to best fit the specificity of each
firewall.
For every peripherals protected by either the ETZPC or the RIFSC, the
firewall framework checks the firewall controlelr registers to see if
the peripheral's access is granted to the Linux kernel. If not, the
peripheral is configured as secure, the node is marked populated,
so that the driver is not probed for that device.
The firewall framework relies on the access-controller device tree
binding. It is used by peripherals to reference a domain access
controller. In this case a firewall controller. The bus uses the ID
referenced by the access-controller property to know where to look
in the firewall to get the security configuration for the peripheral.
This allows a device tree description rather than a hardcoded peripheral
table in the bus driver.
The STM32 ETZPC device is responsible for filtering accesses based on
security level, or co-processor isolation for any resource connected
to it.
The RIFSC is responsible for filtering accesses based on Compartment
ID / security level / privilege level for any resource connected to
it.

Add a new driver for the MSI WMI Platform interface. The underlying
ACPI WMI interface supports many features, but so far only reading
of fan speed sensors is implemented.
The driver was reverse-engineered based on a user request to the
lm-sensors project, see the github issue for details.
The ACPI WMI interface used by this driver seems to use the same
embedded controller interface as the msi-ec driver, but supports
automatic discovery of supported machines without relying on a
DMI whitelist.
The driver was tested by the user who created the github issue.

Virtual Machine Generation ID driver was introduced in commit
af6b54e2b5ba ("virt: vmgenid: notify RNG of VM fork and supply
generation ID"), as an ACPI only device.
VMGenID specification http://go.microsoft.com/fwlink/?LinkId=260709
defines a mechanism for the BIOS/hypervisors to communicate to the
virtual machine that it is executed with a different configuration (e.g.
snapshot execution or creation from a template). The guest operating
system can use the notification for various purposes such as
re-initializing its random number generator etc.
As per the specs, hypervisor should provide a globally unique
identified, or GUID via ACPI.
This patch tries to mimic the mechanism to provide the same
functionality which is for a hypervisor/BIOS to notify the virtual
machine when it is executed with a different configuration.
As part of this support the devicetree bindings requires the hypervisors
or BIOS to provide a memory address which holds the GUID and an IRQ
which is used to notify when there is a change in the GUID. The memory
exposed in the DT should follow the rules defined in the vmgenid spec
mentioned above.
Reason for this change: Chosing ACPI or devicetree is an intrinsic part
of an hypervisor design. Without going into details of why a hypervisor
would chose DT over ACPI, we would like to highlight that the
hypervisors that have chose devicetree and now want to make use of the
vmgenid functionality cannot do so today because vmgenid is an ACPI only
device. This forces these hypervisors to change their design which
could have undesirable impacts on their use-cases, test-scenarios etc.
The point of vmgenid is to provide a mechanism to discover a GUID when
the execution state of a virtual machine changes and the simplest way to
do it is pass a memory location and an interrupt via devicetree. It
would complicate things unnecessarily if instead of using devicetree, we
try to implement a new protocol or modify other protocols to somehow
provide the same functionility.
We believe that adding a devicetree binding for vmgenid is a simpler,
better alternative to provide the same functionality and will allow such
hypervisors as mentioned above to continue using devicetree.
More references to the vmgenid specs are found below.

net: intel: start The Great Code Dedup + Page Pool for iavf
Alexander Lobakin says:
Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and
libie) and switch iavf to Page Pool. Details are in the commit messages;
here's a summary:
Not a secret there's a ton of code duplication between two and more Intel
ethernet modules. Before introducing new changes, which would need to be
copied over again, start decoupling the already existing duplicate
functionality into a new module, which will be shared between several
Intel Ethernet drivers. The first name that came to my mind was
"libie" -- "Intel Ethernet common library". Also this sounds like
"lovelie" (-> one word, no "lib I E" pls) and can be expanded as
"lib Internet Explorer" :P
The "generic", pure-software part is placed separately, so that it can be
easily reused in any driver by any vendor without linking to the Intel
pre-200G guts. In a few words, it's something any modern driver does the
same way, but nobody moved it level up (yet).
The series is only the beginning. From now on, adding every new feature
or doing any good driver refactoring will remove much more lines than add
for quite some time. There's a basic roadmap with some deduplications
planned already, not speaking of that touching every line now asks:
"can I share this?". The final destination is very ambitious: have only
one unified driver for at least i40e, ice, iavf, and idpf with a struct
ops for each generation. That's never gonna happen, right? But you still
can at least try.
PP conversion for iavf lands within the same series as these two are tied
closely. libie will support Page Pool model only, so that a driver can't
use much of the lib until it's converted. iavf is only the example, the
rest will eventually be converted soon on a per-driver basis. That is
when it gets really interesting. Stay tech.
* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
MAINTAINERS: add entry for libeth and libie
iavf: switch to Page Pool
iavf: pack iavf_ring more efficiently
libeth: add Rx buffer management
page_pool: add DMA-sync-for-CPU inline helper
page_pool: constify some read-only function arguments

papr_scm and ndtest share common PDSM payload structs like
nd_papr_pdsm_health. Presently these structs are duplicated across
papr_pdsm.h and ndtest.h header files. Since 'ndtest' is essentially
arch independent and can run on platforms other than PPC64, a way
needs to be deviced to avoid redundancy and duplication of PDSM
structs in future.
So the patch proposes moving the PDSM header from arch/powerpc/include-
-/uapi/ to the generic include/uapi/linux directory. Also, there
are some #defines common between papr_scm and ndtest which are not
exported to the user space. So, move them to a header file which
can be shared across ndtest and papr_scm via newly introduced
include/linux/papr_scm.h.

This driver provides a basic GPIO driver for the Intel Granite Rapids-D
virtual GPIOs. On SoCs with limited physical pins on the package, the
physical pins controlled by this driver would be exposed on an external
device such as a BMC or CPLD. The virtual GPIO registers are an
interface to firmware, which communicates with the external device that
implements the GPIO hardware functionality.

The Analog Device team (Paul Cercueil and Nuno Sa) have been working on
improving high speed device handling. They have had some support in their
own tree for many years, so it is great to see them bring it to upstream.
Some of that is seen here, with the first output device using the
IIO dmaengine infrastructure and a new DAC backend FPGA IP driver.
This makes use of a new set of interfaces to allow backend and
front end driver communication in a fashion that in theory at least
allows for a single driver for a given ADC / DAC independent of
the IP to which is being used to deal with the data bus and DMA aspects
of working with these devices. It is early days for this new
generic way of handling split devices, but as it's kernel internals only
we can merrily change anything about it as a wider diversity of devices
show up and we get a better feel for what works.
Alongside the usual set of new drivers and features we have
the automatic cleanup of fwnode_handle_put() which didn't quite make
it in last cycle. The equivalent DT version was merged by Rob Herring
via the DT binding tree and one patch using that in IIO can also be
found in this pull request. Rob has been making extensive use of that
infrastructure in the DT core which is good to see and provides more
evidence this basic approach is useful.
In some cases, the IIO driver was converted over from DT only to
using the generic firmware description handling of property.h
including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.
avago,apds9306
- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.
New device IDs
==============
For these at most an ID and a instance of chip specific data was needed.
Always nice to see manufacturers sticking to an existing software interface
for new parts.
allwinner,sun20i
- Add support for h616.

ti,dac5571
- Add compatible for DAC081C081
General
=======
fwnode_handle

Features
========
adi,adxl345
- Support SPI_3WIRE mode.
adi,ad9944
- Support 3-wire mode, note this isn't normal 3-wire SPI (unlike the
adxl345 change above), but rather a wiring scheme where the SPI
chip select is used to trigger conversions rather than using a
separate pin.
- Add some device specific documentation, mostly around the various wiring
schemes.
invensense,mpu6050
- Add Wake on Motion support as an IIO event and as a wake-up source.
linear,ltc2983
- Add vdd-supply.
ti,hdc3020
- Add power management using trigger on demand mode and adding suspend and
resume handling.
- Use reset GPIO if available.
Cleanup and fixes
================
iio core
- Use the various autocleanup and lock guards from cleanup.h to simplify
the IIO core.
- Don't set the pointer used for iio_priv() if it is zero sized as that
points beyond the end of the allocation. No driver actually uses it
in that case but good to clean this up.
various drivers
- Drop unnecessary casts of other pointer types to void *
docs
- Add missing ABI entry for in_temp_input.
adi,adx345
- General cleanup prior to adding spi-3wire mode.
adi,axi-adc
- Be more flexible and allow minor version changes as these are expected
to be backwards compatible.
avago,apds9300/9600
- Merge near identical bindings. The drivers are quite different, but
the bindings can be shared. The apds9306 binding introduced in this
series uses this shared binding doc as well.
- Add missing vdd-supply
- Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8.
bosch,bmp280
- Organize headers
freescale,fxl-imx25-gcq
- Use devm_ for remaining probe() time setup allowing dropping
of specific error handling and remove() functions.
infineon,dps310
- Fix handling of negative temperatures
- Bring style of other similar calls inline with the form needed
for temperatures
- Ensure error handling of regmap calls is consistent within the driver.
- Simplify scale reading logic.
invensense,mpu6050
- Flip logic in binding to exclude devices without i2c-gate instead
of opting in. The list is expected to be much shorter as all recent
devices support this feature.
honeywell,hsc030pa
- Use spi_read() instead of opening coding.
renesas,rcar
- Use device_for_each_child_of_node_scoped() to remove need to manually
release. Left over from series the rest of which went in during 6.9.
st,ab8500
- Fix naming of function parameters in kernel-doc

including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.
avago,apds9306
- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.
New device IDs
==============
For these at most an ID and a instance of chip specific data was needed.
Always nice to see manufacturers sticking to an existing software interface
for new parts.
allwinner,sun20i
- Add support for h616.
invensense,mpu6050
- Add support for ICM42688
maxim,max30102
- Add compatible for MAX30101
ti,dac5571
- Add compatible for DAC081C081
General
=======
fwnode_handle
- Support for cleanup.h based __free(fwnode_handle)
- Loop macro using this for looping over child nodes without needing to
call fwnode_handle_put() in ever early exit from the loop.
- Used in:
* adi,ad3552r
* adi,ad4130
* adi,ad5770r
* adi,ad74413r
* adi,ad7173
* adi,adfm2000
* linear,ltc2688
* linear,ltc2983
* maxim,max11410
* microchip,pac1934
* qcom,spmi-adc
* renesas,rz2gl
* st,ab8500
* st,stm32 (Fix for failure to set return value precedes this patch,
providing an example of why enabling direct returns makes bugs
less likely)
- Conversions to fwnode also using the cleanup logic
* adi,ad7124
* adi,ad7292
* freescale,fsl-imx25-gcq
- Other conversions to fwnode where the new cleanup handling isn't useful
* adi,ad7192
* avia,hx711
* freescale,mma8452
* nxp,fxls8962af
* st,spear
* ti,twl4030
Features
========
adi,adxl345
- Support SPI_3WIRE mode.
adi,ad9944
- Support 3-wire mode, note this isn't normal 3-wire SPI (unlike the
adxl345 change above), but rather a wiring scheme where the SPI
chip select is used to trigger conversions rather than using a
separate pin.
- Add some device specific documentation, mostly around the various wiring
schemes.
invensense,mpu6050
- Add Wake on Motion support as an IIO event and as a wake-up source.
linear,ltc2983
- Add vdd-supply.
ti,hdc3020
- Add power management using trigger on demand mode and adding suspend and
resume handling.
- Use reset GPIO if available.
Cleanup and fixes
================
iio core
- Use the various autocleanup and lock guards from cleanup.h to simplify
the IIO core.
- Don't set the pointer used for iio_priv() if it is zero sized as that
points beyond the end of the allocation. No driver actually uses it
in that case but good to clean this up.
various drivers
- Drop unnecessary casts of other pointer types to void *
docs
- Add missing ABI entry for in_temp_input.
adi,adx345
- General cleanup prior to adding spi-3wire mode.
adi,axi-adc
- Be more flexible and allow minor version changes as these are expected
to be backwards compatible.
avago,apds9300/9600
- Merge near identical bindings. The drivers are quite different, but
the bindings can be shared. The apds9306 binding introduced in this
series uses this shared binding doc as well.
- Add missing vdd-supply
- Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8.
bosch,bmp280
- Organize headers
freescale,fxl-imx25-gcq
- Use devm_ for remaining probe() time setup allowing dropping
of specific error handling and remove() functions.
infineon,dps310
- Fix handling of negative temperatures
- Bring style of other similar calls inline with the form needed
for temperatures
- Ensure error handling of regmap calls is consistent within the driver.
- Simplify scale reading logic.
invensense,mpu6050
- Flip logic in binding to exclude devices without i2c-gate instead
of opting in. The list is expected to be much shorter as all recent
devices support this feature.
honeywell,hsc030pa
- Use spi_read() instead of opening coding.
renesas,rcar
- Use device_for_each_child_of_node_scoped() to remove need to manually
release. Left over from series the rest of which went in during 6.9.
st,ab8500
- Fix naming of function parameters in kernel-doc

Add a tool to generate a picture of the current DAPM state for a sound
card.
dapm-graph is inspired by vizdapm which used to be published on a Wolfson
Micro git repository now disappeared, and has a few forks around:
https://github.com/mihais/asoc-toolshttps://github.com/alexandrebelloni/asoc-tools
dapm-graph is a full reimplementation with several improvements while still
being a self-contained shell script:
Improvements to rendered output:
- shows the entire card, not one component hierarchy only
- each component is rendered in a separate box
- shows widget on/off status based on widget information alone (the
original vizdapm propagates the "on" green colour to the first input
widget)
- use bold line and gray background and not only green/red line to show
on/off status (for the color blind)
Improvements for embedded system developers:
- remote mode: get state of remote device (possibly with minimal rootfs)
via SSH, but parsing locally for faster operation
- compatible with BusyBox shell, not only bash
Usability improvements:
- flexible command line (uses getopts for parsing)
- detailed help text
- flag to enable detailed debug logging
- graphviz output format detected from file extension, not hard coded
- a self-contained shell script
Usage is designed to be simple:
dapm-grpah -c CARD - get state from debugfs for CARD
dapm-grpah -c CARD -r REMOTE_TARGET - same, but remotely via SSH
dapm-grpah -d STATE_DIR - from a local copy of the debugfs
tree for a card
