pcim_enable_device() is not related anymore to switching the mode of
operation of any functions. It merely sets up a devres callback for
automatically disabling the PCI device on driver detach.
Adjust the function's documentation.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
callers can't stop a device multiple times, even as we migrate from
the global pci_rescan_remove_lock to finer-grained locking (Keith
Busch)
- Improve pci_walk_bus() implementation by making it recursive and
moving locking up to avoid need for a 'locked' parameter (Keith
Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by
the PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence
'trustworthy' by a heuristic since the 'ExternalFacingPort' and
'usb4-host-interface' ACPI properties are not quite enough (Esther
Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties
when building dynamic DT nodes so systems where PCI and CPU
addresses differ work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce
redundancy (Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish
the conversion from returning 'int' to being 'void' (Sergio
Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request
all BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and
release a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when
there was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay
Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
as required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate()
to create pwrctl platform devices so we can control it based on the
child nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power
supply property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a
race where pwrctl could change device power state while the PCI
driver was active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node()
instead of searching all children of the parent (Manivannan
Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into
pcie_lbms_seen(), where it can be shared between the bandwidth
controller and quirks that use it to help retrain failed links
(Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address
the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers
can manage PCIe Link speed based on thermal or other constraints
(Ilpo Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the
existing thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function
device where function 0 has a management console interface to
enable/disable and provision various personalities for the other
functions (Shijith Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and
doesn't handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and
PCI_ACS_CR were set, so the functions can be in independent IOMMU
groups (Mengyuan Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a
request to the mailbox to avoid failures if the mailbox is still
busy from a previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if
the requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
handle controller-specific size and alignment constraints, and add
test cases to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
observe DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks
'mmio' DT property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when
removing the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware
erratum that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of
clocks for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire
Root Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a
previous commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP
v5.80a and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the
qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
can be used by other Qcom platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the
link comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
to support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation
(Qiang Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
.align value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead
of searching for it, and verify that the address was mapped (Damien
Le Moal)
- When mapping an endpoint window, verify that the address hasn't
been mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to
rockchip_pcie_ep_get_resources() for consistency with similar DT
interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
it only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it
(Damien Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated
resets and start link training after PERST# is deasserted (Damien
Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match
an ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
us), before deasserting PERST# to ensure power and refclk are
stable (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
Complex mode (Kishon Vijay Abraham I)
- Try to avoid unrecoverable SError for attempts to issue config
transactions when the link is down; this is racy but the best we
can do (Kishon Vijay Abraham I)
Miscellaneous:
- Reorganize kerneldoc parameter names to match order in function
signature (Julia Lawall)
- Fix sysfs reset_method_store() memory leak (Todd Kjos)
- Simplify pci_create_slot() (Ilpo Järvinen)

The documentation states that pcim_enable_device() will make "all PCI
ops" managed. This is totally false, only a small subset of PCI
functions become managed that way. Implicating otherwise has caused at
least one bug so far, namely in commit 8558de401b5f ("drm/vboxvideo: use
managed pci functions").
Change the function summary so the functions dangerous behavior becomes
obvious.

Pull spi updates from Mark Brown:
"This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used
in future to allow controllers to directly trigger SPI operations (eg,
from interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages
- A big set of updates from Uwe Kleine-König moving drivers to use
APIs with more modern terminology for controllers
- Major overhaul of the s3c64xx driver

This function allocates a struct pwm_chip and driver data. Compared to
the status quo the split into pwm_chip and driver data is new, otherwise
it doesn't change anything relevant (yet).
The intention is that after all drivers are switched to use this
allocation function, its possible to add a struct device to struct
pwm_chip to properly track the latter's lifetime without touching all
drivers again. Proper lifetime tracking is a necessary precondition to
introduce character device support for PWMs (that implements atomic
setting and doesn't suffer from the sysfs overhead of the /sys/class/pwm
userspace support).
The new function pwmchip_priv() (obviously?) only works for chips
allocated with pwmchip_alloc().

never used in a sysfs callback, so mark it as constant to allow struct
bus_type to be moved to read-only memory.

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"

Pull regulator updates from Mark Brown:
"Quite a quiet release for regulator, the diffstat is dominated by the
I2C migration to probe_new() and the newly added MT6357 driver. We've
just one framework addition and the rest is all new device support,
fixes and cleanups.
The framework addition is an API for requesting all regulators defined
in DT, this isn't great practice but has reasonable applications when
there is generic code handling devices on buses where the bus
specification doesn't include power. The immediate application is MDIO
but I believe there's others, it's another API that'll need an eye
keeping on it for undesirable usage.
Summary:
- An API for requesting all regulators defined in DT
- Conversion of lots of drivers to the I2C probe_new() API
- Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and Richtek

The devm_of_pwm_get() has recently lost its single user, drop
the dead API as well.
Note, the new code should use either plain pwm_get() or managed
devm_pwm_get() or devm_fwnode_pwm_get() APIs.

The last user, which in fact was a dead code, has gone a year ago,
previous one 3 years ago. On top of that we want to drop away the
legacy GPIO APIs in the kernel, so take a chance to get rid of
unused devm_gpio_free() and accompanying stuff.

In some cases, we might need to provide the state of the mux to be set for
the operation of a given peripheral. Therefore, pass this information using
mux-states property.
