When load this mode, we can see the following log:
"power_meter ACPI000D:00: hwmon_device_register() is deprecated. Please
convert the driver to use hwmon_device_register_with_info()."
So replace hwmon_device_register with hwmon_device_register_with_info.
These attributes, 'power_accuracy', 'power_cap_hyst', 'power_average_min'
and 'power_average_max', should have been placed in hwmon_chip_info as
power data type. But these attributes are displayed as string format on
the following case:
a) power1_accuracy --> display like '90.0%'
b) power1_cap_hyst --> display 'unknown' when its value is 0xFFFFFFFF
c) power1_average_min/max --> display 'unknown' when its value is
negative.
To avoid any changes in the display of these sysfs interfaces, we can't
modifiy the type of these attributes in hwmon core and have to put them
to extra_groups.
Please note that the path of these sysfs interfaces are modified
accordingly if use hwmon_device_register_with_info():
old: all sysfs interfaces are under acpi device, namely,
/sys/class/hwmon/hwmonX/device/
now: all sysfs interfaces are under hwmon device, namely,
/sys/class/hwmon/hwmonX/
The new ABI does not guarantee that the underlying path remains the same.
But we have to accept this change so as to replace the deprecated API.
Fortunately, some userspace application, like libsensors, would scan
the two path and handles this automatically. So we can accept this change
so as to drop the deprecated message.

Setting pci_msi_ignore_mask inhibits the toggling of the mask bit for both
MSI and MSI-X entries globally, regardless of the IRQ chip they are using.
Only Xen sets the pci_msi_ignore_mask when routing physical interrupts over
event channels, to prevent PCI code from attempting to toggle the maskbit,
as it's Xen that controls the bit.
However, the pci_msi_ignore_mask being global will affect devices that use
MSI interrupts but are not routing those interrupts over event channels
(not using the Xen pIRQ chip). One example is devices behind a VMD PCI
bridge. In that scenario the VMD bridge configures MSI(-X) using the
normal IRQ chip (the pIRQ one in the Xen case), and devices behind the
bridge configure the MSI entries using indexes into the VMD bridge MSI
table. The VMD bridge then demultiplexes such interrupts and delivers to
the destination device(s). Having pci_msi_ignore_mask set in that scenario
prevents (un)masking of MSI entries for devices behind the VMD bridge.
Move the signaling of no entry masking into the MSI domain flags, as that
allows setting it on a per-domain basis. Set it for the Xen MSI domain
that uses the pIRQ chip, while leaving it unset for the rest of the
cases.
Remove pci_msi_ignore_mask at once, since it was only used by Xen code, and
with Xen dropping usage the variable is unneeded.
This fixes using devices behind a VMD bridge on Xen PV hardware domains.
Albeit Devices behind a VMD bridge are not known to Xen, that doesn't mean
Linux cannot use them. By inhibiting the usage of
VMD_FEAT_CAN_BYPASS_MSI_REMAP and the removal of the pci_msi_ignore_mask
bodge devices behind a VMD bridge do work fine when use from a Linux Xen
hardware domain. That's the whole point of the series.

MSI remapping bypass (directly configuring MSI entries for devices on the
VMD bus) won't work under Xen, as Xen is not aware of devices in such bus,
and hence cannot configure the entries using the pIRQ interface in the PV
case, and in the PVH case traps won't be setup for MSI entries for such
devices.
Until Xen is aware of devices in the VMD bus prevent the
VMD_FEAT_CAN_BYPASS_MSI_REMAP capability from being used when running as
any kind of Xen guest.
The MSI remapping bypass is an optional feature of VMD bridges, and hence
when running under Xen it will be masked and devices will be forced to
redirect its interrupts from the VMD bridge. That mode of operation must
always be supported by VMD bridges and works when Xen is not aware of
devices behind the VMD bridge.

The current hypercall interface for doing PCI device operations always uses
a segment field that has a 16 bit width. However on Linux there are buses
like VMD that hook up devices into the PCI hierarchy at segment >= 0x10000,
after the maximum possible segment enumerated in ACPI.
Attempting to register or manage those devices with Xen would result in
errors at best, or overlaps with existing devices living on the truncated
equivalent segment values. Note also that the VMD segment numbers are
arbitrarily assigned by the OS, and hence there would need to be some
negotiation between Xen and the OS to agree on how to enumerate VMD
segments and devices behind them.
Skip notifying Xen about those devices. Given how VMD bridges can
multiplex interrupts on behalf of devices behind them there's no need for
Xen to be aware of such devices for them to be usable by Linux.

Add mshv_handler() to process messages related to managing guest
partitions such as intercepts, doorbells, and scheduling messages.
In a (non-nested) root partition, the same interrupt vector is shared
between the vmbus and mshv_root drivers.
Introduce a stub for mshv_handler() and call it in
sysvec_hyperv_callback alongside vmbus_handler().
Even though both handlers will be called for every Hyper-V interrupt,
the messages for each driver are delivered to different offsets
within the SYNIC message page, so they won't step on each other.

CONFIG_MSHV_ROOT allows kernels built to run as a normal Hyper-V guest
to exclude the root partition code, which is expected to grow
significantly over time.
This option is a tristate so future driver code can be built as a
(m)odule, allowing faster development iteration cycles.
If CONFIG_MSHV_ROOT is disabled, don't compile hv_proc.c, and stub
hv_root_partition() to return false unconditionally. This allows the
compiler to optimize away root partition code blocks since they will
be disabled at compile time.
In the case of booting as root partition *without* CONFIG_MSHV_ROOT
enabled, print a critical error (the kernel will likely crash).

KVM/arm64 updates for 6.15
- Nested virtualization support for VGICv3, giving the nested
hypervisor control of the VGIC hardware when running an L2 VM
- Removal of 'late' nested virtualization feature register masking,
making the supported feature set directly visible to userspace
- Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
- Paravirtual interface for discovering the set of CPU implementations
where a VM may run, addressing a longstanding issue of guest CPU
errata awareness in big-little systems and cross-implementation VM
migration
- Userspace control of the registers responsible for identifying a
particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
allowing VMs to be migrated cross-implementation
- pKVM updates, including support for tracking stage-2 page table
allocations in the protected hypervisor in the 'SecPageTable' stat
- Fixes to vPMU, ensuring that userspace updates to the vPMU after
KVM_RUN are reflected into the backing perf events

Merge series from Francesco Dolcini <francesco@dolcini.it>:
This patch series adds DMIC and DRC support to the WM8904 driver, a new
of_ helper is added to simplify the driver code.
DRC functionality is added in the same patch series to provide the
necessary dynamic range control to make DMIC support useful.
The WM8904 supports digital microphones on two of its inputs:
IN1L/DMICDAT1 and IN1R/DMICDAT2. These two inputs can either be
connected to an ADC or to the DMIC system. There is an ADC for each
line, and only one DMIC block. This DMIC block is either connected to
DMICDAT1 or to DMICDAT2. One DMIC data line supports two digital
microphones via time multiplexing.
The pin's functionality is decided during hardware design (IN1L vs
DMICDAT1 and IN1R vs DMICDAT2). This is reflected in the Device Tree.
If one line is analog and one is DMIC, we need to be able to switch
between ADC and DMIC at runtime. The DMIC source is known from the
Device Tree. If both are DMIC inputs, we need to be able to switch the
DMIC source. There is no need to switch between ADC and DMIC at runtime.
Therefore, kcontrols are dynamically added by the driver depending on
its Device Tree configuration.
This is a heavy rework of a previous patch series provided by Alifer
Moraes and Pierluigi Passaro,
https://lore.kernel.org/lkml/20220307141041.27538-1-alifer.m@variscite.com.

The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be
lowered to less than 0.5V for a minimum of 1 ms when powering off a
card. Increase wait to 15 ms so that voltage has time to drain down

time were only observed on Apollo Lake and Bay Trail host controllers
so this fix is limited to those devices.

irq allocated with devm_request_irq() will be freed in devm_irq_release(),
using free_irq() in ->remove() will causes a dangling pointer, and a
subsequent double free. So remove the free_irq() in the error path and

Many spi-mem controller drivers have a very similar debug log at the
beginning of their ->exec_op() callback implementation. This debug log is
effectively useful, so let's create one that is complete and concise
enough, so developers no longer need to write their own. The verbosity
being high, VERBOSE_DEBUG will be required in this case.
Remove the debug log from individual drivers and propose a common one.

* kvm-arm64/pv-cpuid:
: Paravirtualized implementation ID, courtesy of Shameer Kolothum
:
: Big-little has historically been a pain in the ass to virtualize. The
: implementation ID (MIDR, REVIDR, AIDR) of a vCPU can change at the whim
: of vCPU scheduling. This can be particularly annoying when the guest
: needs to know the underlying implementation to mitigate errata.
:
: "Hyperscalers" face a similar scheduling problem, where VMs may freely
: migrate between hosts in a pool of heterogenous hardware. And yes, our
: server-class friends are equally riddled with errata too.
:
: In absence of an architected solution to this wart on the ecosystem,
: introduce support for paravirtualizing the implementation exposed
: to a VM, allowing the VMM to describe the pool of implementations that a
: VM may be exposed to due to scheduling/migration.
:
: Userspace is expected to intercept and handle these hypercalls using the
: SMCCC filter UAPI, should it choose to do so.

Previously with tegra-smmu, even with CONFIG_IOMMU_DMA, the default domain
could have been left as NULL. The NULL domain is specially recognized by
host1x_iommu_attach() as meaning it is not the DMA domain and
should be replaced with the special shared domain.
This happened prior to the below commit because tegra-smmu was using the
NULL domain to mean IDENTITY.
Now that the domain is properly labled the test in DRM doesn't see NULL.
Check for IDENTITY as well to enable the special domains.
This is the same issue and basic fix as seen in
commit fae6e669cdc5 ("drm/tegra: Do not assume that a NULL domain means no
DMA IOMMU").

Define an HSMP wrapper in the SMN code and have the HSMP platform driver
use that rather than a local solution.
Also, remove the "root" member from AMD_NB, since there are no more
users of it.

xa_alloc_cyclic() can return 1, which isn't an error. To prevent
situation when the caller of this function will treat it as no error do
a check only for negative here.

In case of returning 1 from xa_alloc_cyclic() (wrapping) ERR_PTR(1) will
be returned, which will cause IS_ERR() to be false. Which can lead to
dereference not allocated pointer (pin).
Fix it by checking if err is lower than zero.
This wasn't found in real usecase, only noticed. Credit to Pierre.

Currently, it seems like the code was carried over from RDNA3 because
it assumes two possible values to set. RDNA4, instead of having:
0: min SCLK
1: max SCLK
only has
0: SCLK offset
This change makes it so it only reports current offset value instead of
showing possible min/max values and their indices. Moreover, it now only
accepts the offset as a value, without the indice index.
Additionally, the lower bound was printed as %u by mistake.

[WHY]
The fw_state in dmub_srv was assigned with wrong address.
The address was pointed to the firmware region.
[HOW]
Fix the firmware state by using DMUB_DEBUG_FW_STATE_OFFSET
in dmub_cmd.h.

[WHY]
DMUB locking is important to make sure that registers aren't accessed
while in PSR. Previously it was enabled but caused a deadlock in
situations with multiple eDP panels.
[HOW]
Detect if multiple eDP panels are in use to decide whether to use
lock. Refactor the function so that the first check is for PSR-SU
and then replay is in use to prevent having to look up number
of eDP panels for those configurations.
