The i.MX SoCs have various power domain configurations routed into
the PCIe IP. MX6SX is the only one which contains 2 domains and also
uses power-domain-names. MX6QDL do not use any domains. All the rest
uses one domain and does not use power-domain-names anymore.
Document all those configurations in the DT binding document.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the set of driver core and kernfs changes for 6.2-rc1.
The "big" change in here is the addition of a new macro,
container_of_const() that will preserve the "const-ness" of a pointer
passed into it.
The "problem" of the current container_of() macro is that if you pass
in a "const *", out of it can comes a non-const pointer unless you
specifically ask for it. For many usages, we want to preserve the
"const" attribute by using the same call. For a specific example, this
series changes the kobj_to_dev() macro to use it, allowing it to be
used no matter what the const value is. This prevents every subsystem
from having to declare 2 different individual macros (i.e.
kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce
the const value at build time, which having 2 macros would not do
either.
The driver for all of this have been discussions with the Rust kernel
developers as to how to properly mark driver core, and kobject,
objects as being "non-mutable". The changes to the kobject and driver
core in this pull request are the result of that, as there are lots of
paths where kobjects and device pointers are not modified at all, so
marking them as "const" allows the compiler to enforce this.
So, a nice side affect of the Rust development effort has been already
to clean up the driver core code to be more obvious about object
rules.
All of this has been bike-shedded in quite a lot of detail on lkml
with different names and implementations resulting in the tiny version
we have in here, much better than my original proposal. Lots of
subsystem maintainers have acked the changes as well.
Other than this change, included in here are smaller stuff like:
- kernfs fixes and updates to handle lock contention better
- vmlinux.lds.h fixes and updates
- sysfs and debugfs documentation updates
- device property updates
All of these have been in the linux-next tree for quite a while with
no problems"

races on the tags being initialised vs the PG_mte_tagged flag as
well as the lack of support for VM_SHARED when KVM is involved.
Patches from Catalin Marinas and Peter Collingbourne").
- Merge the pKVM shadow vcpu state tracking that allows the
hypervisor to have its own view of a vcpu, keeping that state
private.
- Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.
- Fix a handful of minor issues around 52bit VA/PA support (64kB
pages only) as a prefix of the oncoming support for 4kB and 16kB
pages.
- Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.
s390:
- Second batch of the lazy destroy patches
- First batch of KVM changes for kernel virtual != physical address
support
- Removal of a unused function
x86:
- Allow compiling out SMM support
- Cleanup and documentation of SMM state save area format
- Preserve interrupt shadow in SMM state save area
- Respond to generic signals during slow page faults
- Fixes and optimizations for the non-executable huge page errata
fix.
- Reprogram all performance counters on PMU filter change
- Cleanups to Hyper-V emulation and tests
- Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
guest running on top of a L1 Hyper-V hypervisor)
- Advertise several new Intel features
- x86 Xen-for-KVM:
- Allow the Xen runstate information to cross a page boundary
- Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured
- Add support for 32-bit guests in SCHEDOP_poll
- Notable x86 fixes and cleanups:
- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).
- Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
a few years back when eliminating unnecessary barriers when
switching between vmcs01 and vmcs02.
- Clean up vmread_error_trampoline() to make it more obvious that
params must be passed on the stack, even for x86-64.
- Let userspace set all supported bits in MSR_IA32_FEAT_CTL
irrespective of the current guest CPUID.
- Fudge around a race with TSC refinement that results in KVM
incorrectly thinking a guest needs TSC scaling when running on a
CPU with a constant TSC, but no hardware-enumerated TSC
frequency.
- Advertise (on AMD) that the SMM_CTL MSR is not supported
- Remove unnecessary exports
Generic:
- Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks
Selftests:
- Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.
- Fix build errors that occur in certain setups (unsure exactly what
is unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.
- Introduce actual atomics for clear/set_bit() in selftests
- Add support for pinning vCPUs in dirty_log_perf_test.
- Rename the so called "perf_util" framework to "memstress".
- Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress
tests.
- Add a common ucall implementation; code dedup and pre-work for
running SEV (and beyond) guests in selftests.
- Provide a common constructor and arch hook, which will eventually
be used by x86 to automatically select the right hypercall (AMD vs.
Intel).
- A bunch of added/enabled/fixed selftests for ARM64, covering
memslots, breakpoints, stage-2 faults and access tracking.
- x86-specific selftest changes:
- Clean up x86's page table management.
- Clean up and enhance the "smaller maxphyaddr" test, and add a
related test to cover generic emulation failure.
- Clean up the nEPT support checks.
- Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
- Fix an ordering issue in the AMX test introduced by recent
conversions to use kvm_cpu_has(), and harden the code to guard
against similar bugs in the future. Anything that tiggers
caching of KVM's supported CPUID, kvm_cpu_has() in this case,
effectively hides opt-in XSAVE features if the caching occurs
before the test opts in via prctl().
Documentation:
- Remove deleted ioctls from documentation
- Clean up the docs for the x86 MSR filter.
- Various fixes"

This reverts commit 44ecda71fd8a70185c270f5914ac563827fe1d4c.
All versions of this patch on the mailing list, including the version
that ended up getting merged, have portions of code guarded by the
non-existent CONFIG_ARM64_WORKAROUND_2645198 option. Although Anshuman
says he tested the code with some additional debug changes [1], I'm
hesitant to fix the CONFIG option and light up a bunch of code right
before I (and others) disappear for the end of year holidays, during
which time we won't be around to deal with any fallout.
So revert the change for now. We can bring back a fixed, tested version
for a later -rc when folks are thinking about things other than trees
and turkeys.

to other GPIOs
Driver updates:
- convert i2c GPIO expanders to using .probe_new()

Add 'symstr' type for storing the kernel symbol as a string data
instead of the symbol address. This allows us to filter the
events by wildcard symbol name.
e.g.
# echo 'e:wqfunc workqueue.workqueue_execute_start symname=$function:symstr' >> dynamic_events
# cat events/eprobes/wqfunc/format
name: wqfunc
ID: 2110
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1; signed:0;
field:int common_pid; offset:4; size:4; signed:1;
field:__data_loc char[] symname; offset:8; size:4; signed:1;
print fmt: " symname=\"%s\"", __get_str(symname)
Note that there is already 'symbol' type which just change the
print format (so it still stores the symbol address in the tracing
ring buffer.) On the other hand, 'symstr' type stores the actual
"symbol+offset/size" data as a string.

Default value of maxactive is set as num_possible_cpus() for nonpreemptable
systems. For a 2-core system, only 2 kretprobe instances would be allocated
in default, then these 2 instances for execve kretprobe are very likely to
be used up with a pipelined command.
Here's the testcase: a shell script was added to crontab, and the content
of the script is:
#!/bin/sh
do_something_magic `tr -dc a-z < /dev/urandom | head -c 10`
cron will trigger a series of program executions (4 times every hour). Then
events loss would be noticed normally after 3-4 hours of testings.
The issue is caused by a burst of series of execve requests. The best number
of kretprobe instances could be different case by case, and should be user's
duty to determine, but num_possible_cpus() as the default value is inadequate
especially for systems with small number of cpus.
This patch enables the logic for preemption as default, thus increases the
minimum of maxactive to 10 for nonpreemptable systems.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE
and a per-block age-based extent cache.
F2FS_IOC_START_ATOMIC_REPLACE is a variant of the previous atomic
write feature which guarantees a per-file atomicity. It would be more
efficient than AtomicFile implementation in Android framework.
The per-block age-based extent cache implements another type of extent
cache in memory which keeps the per-block age in a file, so that block
allocator could split the hot and cold data blocks more accurately.
Enhancements:
- introduce F2FS_IOC_START_ATOMIC_REPLACE
- refactor extent_cache to add a new per-block-age-based extent cache support
- introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
- add proc entry to show discard_plist info
- optimize iteration over sparse directories
- add barrier mount option
Bug fixes:
- avoid victim selection from previous victim section
- fix to enable compress for newly created file if extension matches
- set zstd compress level correctly
- initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
- correct i_size change for atomic writes
- allow to read node block after shutdown
- allow to set compression for inlined file
- fix gc mode when gc_urgent_high_remaining is 1
- should put a page when checking the summary info
Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and
doc"

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Squash portdrv_{core,pci}.c into portdrv.c to ease maintenance and
make more things static.
- Make portdrv bind to Switch Ports that have AER. Previously, if
these Ports lacked MSI/MSI-X, portdrv failed to bind, which meant
the Ports couldn't be suspended to low-power states. AER on these
Ports doesn't use interrupts, and the AER driver doesn't need to
claim them.
- Assign PCI domain IDs using ida_alloc(), which makes host bridge
add/remove work better.

- To work better with recent BIOSes that use EfiMemoryMappedIO for
PCI host bridge apertures, remove those regions from the E820 map
(E820 entries normally prevent us from allocating BARs). In v5.19,
we added some quirks to disable E820 checking, but that's not very
maintainable. EfiMemoryMappedIO means the OS needs to map the
region for use by EFI runtime services; it shouldn't prevent OS
from using it.
PCIe native device hotplug:
- Build pciehp by default if USB4 is enabled, since Thunderbolt/USB4
PCIe tunneling depends on native PCIe hotplug.
- Enable Command Completed Interrupt only if supported to avoid user
confusion from lspci output that says this is enabled but not
supported.
- Prevent pciehp from binding to Switch Upstream Ports; this happened
because of interaction with acpiphp and caused devices below the
Upstream Port to disappear.
Power management:
- Convert AGP drivers to generic power management. We hope to remove
legacy power management from the PCI core eventually.
Virtualization:
- Fix pci_device_is_present(), which previously always returned
"false" for VFs, causing virtio hangs when unbinding the driver.
Miscellaneous:
- Convert drivers to gpiod API to prepare for dropping some legacy
code.
- Fix DOE fencepost error for the maximum data object length.
Baikal-T1 PCIe controller driver:
- Add driver and DT bindings.
Broadcom STB PCIe controller driver:
- Enable Multi-MSI.
- Delay 100ms after PERST# deassert to allow power and clocks to
stabilize.
- Configure Read Completion Boundary to 64 bytes.
Freescale i.MX6 PCIe controller driver:
- Initialize PHY before deasserting core reset to fix a regression in
v6.0 on boards where the PHY provides the reference.
- Fix imx6sx and imx8mq clock names in DT schema.
Intel VMD host bridge driver:
- Fix Secondary Bus Reset on VMD bridges, which allows reset of NVMe
SSDs in VT-d pass-through scenarios.
- Disable MSI remapping, which gets re-enabled by firmware during
suspend/resume.
MediaTek PCIe Gen3 controller driver:
- Add MT7986 and MT8195 support.
Qualcomm PCIe controller driver:
- Add SC8280XP/SA8540P basic interconnect support.
Rockchip DesignWare PCIe controller driver:
- Base DT schema on common Synopsys schema.
Synopsys DesignWare PCIe core:
- Collect DT items shared between Root Port and Endpoint (PERST GPIO,
PHY info, clocks, resets, link speed, number of lanes, number of
iATU windows, interrupt info, etc) to snps,dw-pcie-common.yaml.
- Add dma-ranges support for Root Ports and Endpoints.
- Consolidate DT resource retrieval for "dbi", "dbi2", "atu", etc. to
reduce code duplication.
- Add generic names for clocks and resets to encourage more
consistent naming across drivers using DesignWare IP.
- Stop advertising PTM Responder role for Endpoints, which aren't
allowed to be responders.
TI J721E PCIe driver:
- Add j721s2 host mode ID to DT schema.
- Add interrupt properties to DT schema.

git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd implementation from Jason Gunthorpe:
"iommufd is the user API to control the IOMMU subsystem as it relates
to managing IO page tables that point at user space memory.
It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO
container) which is the VFIO specific interface for a similar idea.
We see a broad need for extended features, some being highly IOMMU
device specific:
- Binding iommu_domain's to PASID/SSID
- Userspace IO page tables, for ARM, x86 and S390
- Kernel bypassed invalidation of user page tables
- Re-use of the KVM page table in the IOMMU
- Dirty page tracking in the IOMMU
- Runtime Increase/Decrease of IOPTE size
- PRI support with faults resolved in userspace
Many of these HW features exist to support VM use cases - for instance
the combination of PASID, PRI and Userspace IO Page Tables allows an
implementation of DMA Shared Virtual Addressing (vSVA) within a guest.
Dirty tracking enables VM live migration with SRIOV devices and PASID
support allow creating "scalable IOV" devices, among other things.
As these features are fundamental to a VM platform they need to be
uniformly exposed to all the driver families that do DMA into VMs,
which is currently VFIO and VDPA"
