RISC-V Misc Devicetrees for v6.18
Starfive:
The main new addition is support for the JH7110 Milk-V Mars CM lite SoM.
Other than that, there's several cleanups done to the common JH7110 dtsi
file, some relating to properties used by U-Boot or encountered during
U-Boot development. Additionally, there's a binding and devicetree node
for the memory controller on the JH7110. The memory controller only sees
use in U-Boot, so the binding is here rather than in Krzysztof's
branch.
SiFive:
Support for SiFive vendor-specific extensions in the binding file for
extensions. These currently only see use in the SBI implementation.
Microchip:
Addition of support for the PolarFire SoC Discovery kit and
non-engineering sample Icicle kit. The latter differs very slightly from
the final ES devices due to bug fixes affecting functionality, and needs
its own dts. To reduce duplication, the common portion of the two Icicle
kits are moved into a dtsi. There's a few minor fixes here too, mostly
low-hanging fruit detected during the addition of the Discovery kit that
were then applied to the Icicle.

During kernel option migrations (e.g. CONFIG_CFI_CLANG to CONFIG_CFI),
existing .config files need to maintain backward compatibility while
preventing deprecated options from appearing in newly generated
configurations. This is challenging with existing Kconfig mechanisms
because:
1. Simply removing old options breaks existing .config files.
2. Manually listing an option as "deprecated" leaves it needlessly
visible and still writes them to new .config files.
3. Using any method to remove visibility (.e.g no 'prompt', 'if n',
etc) prevents the option from being processed at all.
Add a "transitional" attribute that creates symbols which are:
- Processed during configuration (can influence other symbols' defaults)
- Hidden from user menus (no prompts appear)
- Omitted from newly written .config files (gets migrated)
- Restricted to only having help sections (no defaults, selects, etc)
making it truly just a "prior value pass-through" option.
The transitional syntax requires a type argument and prevents type
redefinition:
config NEW_OPTION
bool "New option"
default OLD_OPTION
config OLD_OPTION
bool
transitional
help
Transitional config for OLD_OPTION migration.
This allows seamless migration: olddefconfig processes existing
CONFIG_OLD_OPTION=y settings to enable CONFIG_NEW_OPTION=y, while
CONFIG_OLD_OPTION is omitted from newly generated .config files.
Added positive and negative testing via "testconfig" make target.

Add support for glitch delay configuration. A detected signal is valid
only if it remains stable longer than the configured delay; otherwise,
it is considered a glitch.
This property was introduced for the i.MX6UL touchscreen controller (TSC),
which provides a hardware deglitch filter with four thresholds depending
on the IPG clock frequency. In this use case, the IPG clock rate is 66 MHz,
resulting in thresholds of 124 µs, 62 µs, 31 µs, and 15 µs, which requires
a property with microsecond-level resolution.

Many machines treat fan state 3 as some sort of automatic mode,
which is superior to the separate SMM calls for switching to
automatic fan mode for two reasons:
- the fan control mode can be controlled for each fan separately
- the current fan control mode can be retrieved from the BIOS
On some machines however, this special fan state does not exist.
Fan state 3 acts like a regular fan state on such machines or
does not exist at all. Such machines usually use separate SMM calls
for enabling/disabling automatic fan control.
Add support for it. If the machine supports separate SMM calls
for changing the fan control mode, then the other interface is
ignored.

Add Qualcomm TEE driver (QTEE)
This introduces a Trusted Execution Environment (TEE) driver for
Qualcomm TEE (QTEE).
QTEE enables Trusted Applications (TAs) and services to run securely. It
uses an object-based interface, where each service is an object with
sets of operations.
Kernel and userspace services are also available to QTEE through a
similar approach. QTEE makes callback requests that are converted into
object invocations. These objects can represent services within the
kernel or userspace process.
We extend the TEE subsystem to understand object parameters and an ioctl
call so client can invoke objects in QTEE:
- TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_*
- TEE_IOC_OBJECT_INVOKE
The existing ioctl calls TEE_IOC_SUPPL_RECV and TEE_IOC_SUPPL_SEND are
used for invoking services in the userspace process by QTEE.
The TEE backend driver uses the QTEE Transport Message to communicate
with QTEE. Interactions through the object INVOKE interface are
translated into QTEE messages. Likewise, object invocations from QTEE
for userspace objects are converted into SEND/RECV ioctl calls to
supplicants.

Apple SoC driver updates for 6.18
Krzysztof Kozlowski asked us to move away from generic compatibles:
- Adjust all dt-bindings to use apple,t8103-XXXX instead of apple,XXXX
as fallback and add a comment that the old generic list should no
longer be extended.
- Add new fallback compatibles to pinctrl, pmdomain, spi, and mca
drivers. These changes have been Acked by their subsystem maintainers
to be merged through our tree together with the dt-bindings.
Support for pre-M1 Apple Silicon:
- SART and mailbox gain support for Apple's A11, which are both
required for NVMe.
- NVMe also gains support for Apple's A11 and the nvme maintainers
prefer that we merge this through the soc tree together with
the mailbox and SART changes.
- SPMI compatibles for A11 and T2 have been added, also going through
the soc tree due to conflicts with the generic compatible removal and
because no driver change is required.

Allwinner Device Tree changes for 6.18
This tag contains two DT binding header changes that are shared with
the clk tree.
In this cycle we gained support for the MCU PRCM clock and reset
controller on the A523/A527/T527 family of SoCs, the NPU which is a
Vivante GC9000 IP block, and the NPU clock that was missing. The other
PRCM clock controller gained default bus clock rate settings. These
were not configured in the upstream U-boot bootloader, leading to them
running at slower rates. The assigned rates are from the user manual.
There is also a new board, the NetCube Systems Nagami SoM and two of
its carrier boards.
The A523 family development boards now have their internal RTC clocks
configured correctly, so that the RTC does not drift wildly. The missing
functions for the AXP717 on these boards are added. Missing reset GPIOs
and delays for Ethernet PHYs are added. Last, the Cubie A5E now has its
LEDs described and usable.
An overlay for the Orange Pi Zero interface (addon) board was added.
This can be used with the Orange Pi Zero and Zero Plus 2. Default audio
routing for these two boards (to be used with the addon) were added to
complement the overlay.

Add a KVM-defined ONE_REG register, KVM_REG_GUEST_SSP, to let userspace
save and restore the guest's Shadow Stack Pointer (SSP). On both Intel
and AMD, SSP is a hardware register that can only be accessed by software
via dedicated ISA (e.g. RDSSP) or via VMCS/VMCB fields (used by hardware
to context switch SSP at entry/exit). As a result, SSP doesn't fit in
any of KVM's existing interfaces for saving/restoring state.
Internally, treat SSP as a fake/synthetic MSR, as the semantics of writes
to SSP follow that of several other Shadow Stack MSRs, e.g. the PLx_SSP
MSRs. Use a translation layer to hide the KVM-internal MSR index so that
the arbitrary index doesn't become ABI, e.g. so that KVM can rework its
implementation as needed, so long as the ONE_REG ABI is maintained.
Explicitly reject accesses to SSP if the vCPU doesn't have Shadow Stack
support to avoid running afoul of ignore_msrs, which unfortunately applies
to host-initiated accesses (which is a discussion for another day). I.e.
ensure consistent behavior for KVM-defined registers irrespective of
ignore_msrs.

Enable KVM_{G,S}ET_ONE_REG uAPIs so that userspace can access MSRs and
other non-MSR registers through them, along with support for
KVM_GET_REG_LIST to enumerate support for KVM-defined registers.
This is in preparation for allowing userspace to read/write the guest SSP
register, which is needed for the upcoming CET virtualization support.
Currently, two types of registers are supported: KVM_X86_REG_TYPE_MSR and
KVM_X86_REG_TYPE_KVM. All MSRs are in the former type; the latter type is
added for registers that lack existing KVM uAPIs to access them. The "KVM"
in the name is intended to be vague to give KVM flexibility to include
other potential registers. More precise names like "SYNTHETIC" and
"SYNTHETIC_MSR" were considered, but were deemed too confusing (e.g. can
be conflated with synthetic guest-visible MSRs) and may put KVM into a
corner (e.g. if KVM wants to change how a KVM-defined register is modeled
internally).
Enumerate only KVM-defined registers in KVM_GET_REG_LIST to avoid
duplicating KVM_GET_MSR_INDEX_LIST, and so that KVM can return _only_
registers that are fully supported (KVM_GET_REG_LIST is vCPU-scoped, i.e.
can be precise, whereas KVM_GET_MSR_INDEX_LIST is system-scoped).

Current name of coresight component's folder consists of prefix of
the device and the id in the device list. When run 'ls' command,
we can get the register address of the device. Take CTI for example,
if we want to set the config for modem CTI, but we can't know which
CTI is modem CTI from all current information.
cti_sys0 -> ../../../devices/platform/soc@0/138f0000.cti/cti_sys0
cti_sys1 -> ../../../devices/platform/soc@0/13900000.cti/cti_sys1
Add label to show hardware context information of each coresight
device. There will be a sysfs node label in each device folder.

IIO: New device support, features and cleanup for 6.18
New device support
==================
ad,ade9000
- New driver for this complex energy and power monitoring ADC.
infineon,tlv493d
- New driver for this 3D magnetic sensor.
intel,dollar
- New driver for this TI PMIC (part number unknown)
marvel,88pm886
- Driver for this PMIC ADC.
microchip,mcp9600
- Add explicit support for the mcp9601 which has some additional features
over the mcp9600.
rohm,bd79112
- New driver for this ADC / GPIO Chip.
Features
========
Core
- New helper to multiply data expressed in IIO types.
- Add KUnit tests.
- New IIO_ALTCURRENT type, similar to existing IIO_ALTVOLTAGE
- Add some channel modifiers related to energy and power, such as
reactive.
adi,ad7124
- Support external clocks sources and output of the internal clocks.
- Filter control.
adi,ad7173
- Add filter support. Some fiddly interactions with other parameters on this
device.
adi,ad7779
- Add backend support which required control of the number of lanes used.
liteon,ltr390
- Add runtime PM support.
microchip,mcp9600
- Add support for different thermocouple types.
Cleanup and minor fixes
=======================
core
- Switch info_mask fields to be unsigned. Not clear why they were ever
signed.
- Fix handling of negative channel scale in iio_convert_raw_to_processed()
- Fix offset handling for channels without a scale attribute.
- Improve the precision of scaling slightly.
- Drop apparent handling of IIO_CHAN_INFO_PROCESSED for devices that don't
have any such channels.
various
- Drop many pm_runtime_mark_last_busy() calls now
pm_runtime_put_autosuspend() calls it internally.
- Drop dev_err_probe() calls where the error code is hard coded as -ENOMEM
as they don't do anything.
- Drop dev_err() calls where the error code is -ENOMEM. This will reduce
error prints, but memory failures generate a lot of messages anyway
so unlikely we need these prints.
current-sense-amplifier
- Add #io-channels property this channel to be used by a consumer driver.
adi,ad7124
- Fix incorrect clocks dt-binding property.
- Make the mclk clock optional in DT - this is internal to the ADC so should
never have been in he binding.
- Fix up sample rate to comply with ABI.
- Use read_avail() callback rather than opencoding similar.
- Deploy guard() to clean up some lock handling.
adi,ad7768
- Use devm_regulator_get_enable_read_voltage() to replace similar code.
adi,ad7816
- Drop an unnecessary dev_set_drvdata() call as nothing uses the data.
ad,adxl345
- Fix missing blank line before bullet list in documentation.
arm,scmi
- Use devm_kcalloc() for an array allocation rather than devm_kzalloc().
bosch,bmi270
- Match an ACPI ID seen in the wild. It is not spec compliant but we can't
do much about that.
bosch,bmp280
- Drop overly noisy dev_info()
- Allow for sleeping gpio controllers.
gogle,cros-ec
- Drop unused location attribute that has been replaced by label.
invense,icm42600
- Simplify the power management.
- Use guard() to simplify some locking.
maxim,max1238
- Add io-channel-cells property to dt-binding as there is an in tree
consumer.
microchip,mcp9600
- Specify a default value in dt-binding for the thermocouple type
- General whitespace cleanup.
samsung,exynos
- Drop support for the S3C2410 including bindings, and touchscreen support
as nothing else uses that.
- Drop platform ID based binding as not used.
st,vl53l0x
- Fix returning the wrong variable in an error path.
ti,pac1934
- Replace open coded devm_mutex_init().
xilinx,ams
- Update maintainers entry.

kern_path_locked() is now only used to prepare for removing an object
from the filesystem (and that is the only credible reason for wanting a
positive locked dentry). Thus it corresponds to kern_path_create() and
so should have a corresponding name.
Unfortunately the name "kern_path_create" is somewhat misleading as it
doesn't actually create anything. The recently added
simple_start_creating() provides a better pattern I believe. The
"start" can be matched with "end" to bracket the creating or removing.
So this patch changes names:
kern_path_locked -> start_removing_path
kern_path_create -> start_creating_path
user_path_create -> start_creating_user_path
user_path_locked_at -> start_removing_user_path_at
done_path_create -> end_creating_path
and also introduces end_removing_path() which is identical to
end_creating_path().
__start_removing_path (which was __kern_path_locked) is enhanced to
call mnt_want_write() for consistency with the start_creating_path().

Merge series from Biju Das <biju.das.jz@bp.renesas.com>:
On RZ/G3E using PSCI, s2ram powers down the SoC. After resume,
reinitialize the hardware for SPI operations.
Also Replace the macro SIMPLE_DEV_PM_OPS->DEFINE_SIMPLE_DEV_PM_OPS macro
and use pm_sleep_ptr(). This lets us drop the check for CONFIG_PM_SLEEP
and __maybe_unused attribute from PM functions.
