soc: driver updates for 6.19
This is the first half of the driver changes:
- A treewide interface change to the "syscore" operations for
power management, as a preparation for future Tegra specific
changes.
- Reset controller updates with added drivers for LAN969x, eic770
and RZ/G3S SoCs.
- Protection of system controller registers on Renesas and Google SoCs,
to prevent trivially triggering a system crash from e.g. debugfs
access.
- soc_device identification updates on Nvidia, Exynos and Mediatek
- debugfs support in the ST STM32 firewall driver
- Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI
- Cleanups for memory controller support on Nvidia and Renesas

Some filesystems use a kinda-sorta controlled dentry refcount leak to pin
dentries of created objects in dcache (and undo it when removing those).
Reference is grabbed and not released, but it's not actually _stored_
anywhere. That works, but it's hard to follow and verify; among other
things, we have no way to tell _which_ of the increments is intended
to be an unpaired one. Worse, on removal we need to decide whether
the reference had already been dropped, which can be non-trivial if
that removal is on umount and we need to figure out if this dentry is
pinned due to e.g. unlink() not done. Usually that is handled by using
kill_litter_super() as ->kill_sb(), but there are open-coded special
cases of the same (consider e.g. /proc/self).
Things get simpler if we introduce a new dentry flag (DCACHE_PERSISTENT)
marking those "leaked" dentries. Having it set claims responsibility
for +1 in refcount.
The end result this series is aiming for:
* get these unbalanced dget() and dput() replaced with new primitives that
would, in addition to adjusting refcount, set and clear persistency flag.
* instead of having kill_litter_super() mess with removing the remaining
"leaked" references (e.g. for all tmpfs files that hadn't been removed
prior to umount), have the regular shrink_dcache_for_umount() strip
DCACHE_PERSISTENT of all dentries, dropping the corresponding
reference if it had been set. After that kill_litter_super() becomes
an equivalent of kill_anon_super().
Doing that in a single step is not feasible - it would affect too many places
in too many filesystems. It has to be split into a series.
This work has really started early in 2024; quite a few preliminary pieces
have already gone into mainline. This chunk is finally getting to the
meat of that stuff - infrastructure and most of the conversions to it.
Some pieces are still sitting in the local branches, but the bulk of
that stuff is here.

gpio updates for v6.19-rc1
GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot enable
counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone to
bugs (GPIO controllers don't have to use the software node's name as
their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device code
New drivers:
- add a driver for the QIXIS FPGA GPIO controller
Driver improvements:
- use modernized variants of power management macros across a wide array
of drivers in order to avoid having to use the __maybe_unused attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to user-space
in gpio-virtuser (this was previously not possible as this function
returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary calls
to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio
Device-tree bindings:
- document new NXP and Microchip models
Documentation:
- add a comprehensive compatibility and feature list for gpio-pca953x,
which is a great addition as it's probably the most commonly used GPIO
expander driver
- kernel-doc tweaks
Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, lots of various updates to existing ones, some
refactoring support for new models and misc tweaks and fixes.
The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.

- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot
enable counting) and enable it for Qualcomm platforms

regmap: Updates for v6.19
Another small update for regmap, we have one new feature plus a little
bit of cleanup:
- Support for sparseness information in the flat cache, allowing users
that really need the performance properties it provides to benefit
from the interface and startup time improvements that sparsness provides
without needing to go all the way to a more fancy data structure.
- Cleanup work from Andy Shevchenko, refactoring the cache interface
in preparation for some future stuff he's working on.

Wildcat Lake, Noval Lake, and Diamond Rapids in the OOB mode, OPP and
bandwidth allocation support in the tegra186 cpufreq driver, and
JH7110S SOC support in dt-platdev cpufreq.
The new features are the PM QoS CPU latency limit for suspend-to-idle,
the netlink support for the energy model management, support for
terminating system suspend via a wakeup event during the sync of file
systems, configurable number of hibernation compression threads, the
runtime PM auto-cleanup macros, and the "poweroff" PM event that is
expected to be used during system shutdown.
Bugs are mostly fixed in cpuidle governors, but there are also fixes
elsewhere, like in the amd-pstate cpufreq driver.
Documentation updates include, but are not limited to, a new doc on
debugging shutdown hangs, cross-referencing fixes and cleanups in the
intel_pstate documentation, and updates of comments in the core
hibernation code.

Updates for the interrupt core and treewide cleanups:
- Rework of the Per Processor Interrupt (PPI) management on ARM[64].
PPI support was built under the assumption that the systems are
homogenous so that the same CPU local device types are connected to
them. That's unfortunately wishful thinking and created horrible
workarounds.
This rework provides affinity management for PPIs so that they can be
individually configured in the firmware tables and mops up the related
drivers all over the place.
- Prevent CPUSET/isolation changes to arbitrarily affine interrupt
threads to random CPUs, which ignores user or driver settings.
- Plug a harmless race in the interrupt affinity proc interface, which
allows to see a half updated mask
- Adjust the priority of secondary interrupt threads on RT, so that the
combination of primary and secondary thread emulates the hardware
interrupt plus thread scenario. Having them at the same priority can
cause starvation issues in some drivers.

Pull directory delegations update from Christian Brauner:
"This contains the work for recall-only directory delegations for
knfsd.
Add support for simple, recallable-only directory delegations. This
was decided at the fall NFS Bakeathon where the NFS client and server
maintainers discussed how to merge directory delegation support.
The approach starts with recallable-only delegations for several reasons:
1. RFC8881 has gaps that are being addressed in RFC8881bis. In
particular, it requires directory position information for
CB_NOTIFY callbacks, which is difficult to implement properly
under Linux. The spec is being extended to allow that information
to be omitted.
2. Client-side support for CB_NOTIFY still lags. The client side
involves heuristics about when to request a delegation.
3. Early indication shows simple, recallable-only delegations can
help performance. Anna Schumaker mentioned seeing a multi-minute
speedup in xfstests runs with them enabled.
With these changes, userspace can also request a read lease on a
directory that will be recalled on conflicting accesses. This may be
useful for applications like Samba. Users can disable leases
altogether via the fs.leases-enable sysctl if needed.
VFS changes:
- Dedicated Type for Delegations
Introduce struct delegated_inode to track inodes that may have
delegations that need to be broken. This replaces the previous
approach of passing raw inode pointers through the delegation
breaking code paths, providing better type safety and clearer
semantics for the delegation machinery.
- Break parent directory delegations in open(..., O_CREAT) codepath
- Allow mkdir to wait for delegation break on parent
- Allow rmdir to wait for delegation break on parent
- Add try_break_deleg calls for parents to vfs_link(), vfs_rename(),
and vfs_unlink()
- Make vfs_create(), vfs_mknod(), and vfs_symlink() break delegations
on parent directory
- Clean up argument list for vfs_create()
- Expose delegation support to userland
Filelock changes:
- Make lease_alloc() take a flags argument
- Rework the __break_lease API to use flags
- Add struct delegated_inode
- Push the S_ISREG check down to ->setlease handlers
- Lift the ban on directory leases in generic_setlease

- Allow filecache to hold S_IFDIR files

- Fix kernel-doc warnings in __fcntl_getlease

Merge tag 'kernel-6.19-rc1.cred' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull cred guard updates from Christian Brauner:
"This contains substantial credential infrastructure improvements
adding guard-based credential management that simplifies code and
eliminates manual reference counting in many subsystems.
Features:
- Kernel Credential Guards
Add with_kernel_creds() and scoped_with_kernel_creds() guards that
allow using the kernel credentials without allocating and copying
them. This was requested by Linus after seeing repeated
prepare_kernel_creds() calls that duplicate the kernel credentials
only to drop them again later.
The new guards completely avoid the allocation and never expose the
temporary variable to hold the kernel credentials anywhere in
callers.
- Generic Credential Guards
Add scoped_with_creds() guards for the common override_creds() and
revert_creds() pattern. This builds on earlier work that made
override_creds()/revert_creds() completely reference count free.
- Prepare Credential Guards
Add prepare credential guards for the more complex pattern of
preparing a new set of credentials and overriding the current
credentials with them:
- prepare_creds()
- modify new creds
- override_creds()
- revert_creds()
- put_cred()
Cleanups:
- Make init_cred static since it should not be directly accessed
- Add kernel_cred() helper to properly access the kernel credentials
- Fix scoped_class() macro that was introduced two cycles ago
- coredump: split out do_coredump() from vfs_coredump() for cleaner
credential handling

software node: allow referencing firmware nodes
At the moment software nodes can only reference other software nodes. This is a limitation for devices created, for instance, on the auxiliary bus with a dynamic software node attached which cannot reference devices the firmware node of which is "real" (as an OF node or otherwise). Make it possible for a software node to reference all firmware nodes in addition to static software nodes. To that end: add a second pointer to struct software_node_ref_args of type struct fwnode_handle. The core swnode code will first check the swnode pointer and if it's NULL, it will assume the fwnode pointer should be set. Software node graphs remain the same, as in: the remote endpoints still have to be software nodes.

PM: wakeup: Add out-of-band system wakeup support for devices
Some devices can wake up the system from suspend even when their power domains are turned off. This is possible because their system-wakeup logic resides in an always-on power domain - indicating that they support out-of-band system wakeup. Currently, PM domain core doesn't power off such devices if they are marked as system wakeup sources. To better represent devices with out-of-band wakeup capability, this patch introduces a new flag out_band_wakeup in 'struct dev_pm_info'. Two helper APIs are added: - device_set_out_band_wakeup() - to mark a device as having out-of-band wakeup capability. - device_out_band_wakeup() - to query the flag. Allow the PM core and drivers to distinguish between regular and out-of-band wakeup sources, enable more accurate power management decision.

PM: sleep: core: Fix runtime PM enabling in device_resume_early()
Runtime PM should only be enabled in device_resume_early() if it has
been disabled for the given device by device_suspend_late(). Otherwise,
it may cause runtime PM callbacks to run prematurely in some cases
which leads to further functional issues.
Make two changes to address this problem.
First, reorder device_suspend_late() to only disable runtime PM for a
device when it is going to look for the device's callback or if the
device is a "syscore" one. In all of the other cases, disabling runtime
PM for the device is not in fact necessary. However, if the device's
callback returns an error and the power.is_late_suspended flag is not
going to be set, enable runtime PM so it only remains disabled when
power.is_late_suspended is set.
Second, make device_resume_early() only enable runtime PM for the
devices with the power.is_late_suspended flag set.

convert ramfs and tmpfs
Quite a bit is already done by infrastructure changes (simple_link(),
simple_unlink()) - all that is left is replacing d_instantiate() +
pinning dget() (in ->symlink() and ->mknod()) with d_make_persistent(),
and, in case of shmem, using simple_unlink() and simple_link() in
->unlink() and ->link() resp., instead of open-coding those there.
Since d_make_persistent() accepts (and hashes) unhashed ones, shmem
situation gets simpler - we no longer care whether ->lookup() has hashed
the sucker.
With that done, we don't need kill_litter_super() for these filesystems
anymore - by the umount time all remaining dentries will be marked
persistent and kill_litter_super() will boil down to call of
kill_anon_super().
The same goes for devtmpfs and rootfs - they are handled by
ramfs or by shmem, depending upon config.
NB: strictly speaking, both devtmpfs and rootfs ought to use
ramfs_kill_sb() if they end up using ramfs; that's a separate
story and the only impact of "just use kill_{litter,anon}_super()"
is that we fail to free their sb->s_fs_info... on reboot.
That's orthogonal to the changes in this series - kill_litter_super()
is identical to kill_anon_super() for those at this point.

Hibernation is started by writing a hibernation method (such as 'platform' 'shutdown', or 'reboot') to use into /sys/power/disk and writing 'disk' to /sys/power/state. Shutdown is initiated with the reboot() syscall with arguments on whether to halt the system or power it off.

PM: wakeup: Delete timer before removing wakeup source from list
Replace timer_delete_sync() with timer_shutdown_sync() and move it before list_del_rcu() in wakeup_source_remove() to improve the cleanup ordering and code clarity. This ensures that the timer is stopped before removing the wakeup source from the events list, providing a more logical cleanup sequence. While the current ordering is functionally correct, stopping the timer first makes the cleanup flow more intuitive and follows the general pattern of disabling active components before removing data structures.

regmap: warn users about uninitialized flat cache
The standard flat cache did not contain any validity info, so the cache was always considered to be entirely valid. Multiple mechanisms exist to initialize the cache on regmap init (defaults, raw defaults, HW init), but not all drivers are using one of these. As a result, their implementation might currently depend on the zero-initialized cache or contain other workarounds. When reading an uninitialized value from the flat cache, warn the user, but maintain the current behavior. This will allow developers to switch to a sparse (flat) cache independently.

The flat regcache will always assume the data in the cache is valid. Since the cache is preferred over hardware access, this may shadow the actual state of the device. Add a new containing cache structure with the flat data table and a bitmap indicating cache validity. REGCACHE_FLAT will still behave as before, as the validity is ignored. Define new cache type REGCACHE_FLAT_S: a flat cache with sparse validity. The sparse validity is used to determine if a hardware access should occur to initialize the cache on the fly, vs. at regmap init for REGCACHE_FLAT. Contrary to REGCACHE_FLAT, this allows us to implement regcache_ops.drop.

Add SDCA UMP/FDL support
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
Next installment of the SDCA changes, hopefully the next series after
this should be the full class driver. It is worth noting this series has
a build dependency on a patch working its way through the PM/ACPI tree:

platform: Add firmware-agnostic irq and affinity retrieval interface
Expand platform_get_irq_optional() to also return an affinity if available, renaming it to platform_get_irq_affinity() in the process. platform_get_irq_optional() is preserved with its current semantics by calling into the new helper with a NULL affinity pointer.
