Introduce ABI documentation for new modifiers used for reporting rotations
expressed as euler angles (i.e. yaw, pitch, roll).
It looks like we have some unit inconsistency along various IIO modifiers:
it seems that incli is in deg, angl is in radians and rot isn't documented,
but at least the adis16209 driver has rot in deg.
Here we use deg (so angl is the only one using radians).

In modern Chromebooks, the embedded controller has a mechanism where
it will watch a hardware-controlled line that toggles in suspend, and
wake the system up if an expected sleep transition didn't occur. This
can be very useful for detecting power management issues where the
system appears to suspend, but doesn't actually reach its lowest
expected power states.
Sometimes it's useful in debug and test scenarios to be able to control
the duration of that timeout, or even disable the EC timeout mechanism
altogether. Add a debugfs control to set the timeout to values other
than the EC-defined default, for more convenient debug and
development iteration.

There is the following quirk to bypass "WB Flush" in Write Booster.
- UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL
If this quirk is not set, there is no knob that can control "WB Flush".
There are three flags that control Write Booster Feature:
1. WB ON/OFF
2. WB Hibern Flush ON/OFF (implicitly)
3. WB Flush ON/OFF (explicit)
The sysfs attribute that controls the WB was implemented. (1)
In the case of "Hibern Flush", it is always good to turn on. Control may
not be required. (2)
Finally, "Flush" may be necessary because the Auto-Hibern8 is not supported
in a specific environment. So the sysfs attribute that controls this is
necessary. (3)

Address an ABI gap for device where the offset of both lines in a
differential pair may be controlled so as to allow a wider range of
inputs, but without having any direct effect of the differential
measurement.
_offset cannot be used as to remain in line with existing usage,
userspace would be expected to apply it as (_raw + _offset) * _scale
whereas _zeropoint is not. i.e. If we were computing the differential
in software it would be.
((postive_raw + _zeropoint) - (negative_raw + zeropoint) + _offset) * _scale
= ((postive_raw - negative_raw) + _offset) * _scale
= (differential_raw + _offset) * _scale
Similarly calibbias is expected to tweak the measurement seen, not
the adjust the two lines of the differential pair.

x86/xen: Add support for HVMOP_set_evtchn_upcall_vector
In some use cases[1], the backend is created while the frontend doesn't
support the persistent grants feature, but later the frontend can be
changed to support the feature and reconnect. In the past, 'blkback'
enabled the persistent grants feature since it unconditionally checked
if frontend supports the persistent grants feature for every connect
('connect_ring()') and decided whether it should use persistent grans or
not.
However, commit aac8a70db2 ("xen-blkback: add a parameter for
disabling of persistent grants") has mistakenly changed the behavior.
It made the frontend feature support check to not be repeated once it
shown the 'feature_persistent' as 'false', or the frontend doesn't
support persistent grants.
Similar behavioral change has made on 'blkfront' by commit 74a852479c
("xen-blkfront: add a parameter for disabling of persistent grants").
This commit changes the behavior of the parameter to make effect for
every connect, so that the previous behavior of 'blkfront' can be
restored.

In this cycle, we mainly fixed some corner cases that manipulate a per-file
compression flag inappropriately. And, we found f2fs counted valid blocks in a
section incorrectly when zone capacity is set, and thus, fixed it with
additional sysfs entry to check it easily. Lastly, this series includes
several patches with respect to the new atomic write support such as a
couple of bug fixes and re-adding atomic_write_abort support that we removed
by mistake in the previous release.
Enhancement:
- add sysfs entries to understand atomic write operations and zone
capacity
- introduce memory mode to get a hint for low-memory devices
- adjust the waiting time of foreground GC
- decompress clusters under softirq to avoid non-deterministic latency
- do not skip updating inode when retrying to flush node page
- enforce single zone capacity
Bug fix:
- set the compression/no-compression flags correctly
- revive F2FS_IOC_ABORT_VOLATILE_WRITE
- check inline_data during compressed inode conversion
- understand zone capacity when calculating valid block count
As usual, the series includes several minor clean-ups and sanity checks.

Here is the big set of Thunderbolt and USB changes for 6.0-rc1.
Lots of little things here, nothing major, just constant development on
some new hardware support and cleanups of older drivers. Highlights of
this pull request are:
- lots of typec changes and improvements for new hardware
- new gadget controller driver
- thunderbolt support for new hardware
- the normal set of new usb-serial device ids and cleanups
- loads of dwc3 controller fixes and improvements
- mtu3 driver updates
- testusb fixes for longtime issues (not many people use this
tool it seems.)
- minor driver fixes and improvements over the USB tree
- chromeos platform driver changes were added and then reverted
as they depened on some typec changes, but the cross-tree
merges caused problems so they will come back later through
the platform tree.
All of these have been in linux-next for a while now with no reported
issues.

Pull networking changes from Paolo Abeni:
"Core:
- Refactor the forward memory allocation to better cope with memory
pressure with many open sockets, moving from a per socket cache to
a per-CPU one
- Replace rwlocks with RCU for better fairness in ping, raw sockets
and IP multicast router.
- Network-side support for IO uring zero-copy send.
- A few skb drop reason improvements, including codegen the source
file with string mapping instead of using macro magic.
- Rename reference tracking helpers to a more consistent netdev_*
schema.

After all the soft validation of the region has completed, convey the
region configuration to hardware while being careful to commit decoders
in specification mandated order. In addition to programming the endpoint
decoder base-address, interleave ways and granularity, the switch
decoder target lists are also established.
While the kernel can enforce spec-mandated commit order, it can not
enforce spec-mandated reset order. For example, the kernel can't stop
someone from removing an endpoint device that is occupying decoderN in a
switch decoder where decoderN+1 is also committed. To reset decoderN,
decoderN+1 must be torn down first. That "tear down the world"
implementation is saved for a follow-on patch.
Callback operations are provided for the 'commit' and 'reset'
operations. While those callbacks may prove useful for CXL accelerators
(Type-2 devices with memory) the primary motivation is to enable a
simple way for cxl_test to intercept those operations.

The region provisioning process involves allocating DPA to a set of
endpoint decoders, and HPA plus the region geometry to a region device.
Then the decoder is assigned to the region. At this point several
validation steps can be performed to validate that the decoder is
suitable to participate in the region.

After a region's interleave parameters (ways and granularity) are set,
add a way for regions to allocate HPA (host physical address space) from
the free capacity in their parent root-decoder. The allocator for this
capacity reuses the 'struct resource' based allocator used for
CONFIG_DEVICE_PRIVATE.
Once the tuple of "ways, granularity, [uuid], and size" is set the
region configuration transitions to the CXL_CONFIG_INTERLEAVE_ACTIVE
state which is a precursor to allowing endpoint decoders to be added to
a region.

CXL 2.0 allows for dynamic provisioning of new memory regions (system
physical address resources like "System RAM" and "Persistent Memory").
Whereas DDR and PMEM resources are conveyed statically at boot, CXL
allows for assembling and instantiating new regions from the available
capacity of CXL memory expanders in the system.
Sysfs with an "echo $region_name > $create_region_attribute" interface
is chosen as the mechanism to initiate the provisioning process. This
was chosen over ioctl() and netlink() to keep the configuration
interface entirely in a pseudo-fs interface, and it was chosen over
configfs since, aside from this one creation event, the interface is
read-mostly. I.e. configfs supports cases where an object is designed to
be provisioned each boot, like an iSCSI storage target, and CXL region
creation is mostly for PMEM regions which are created usually once
per-lifetime of a server instance. This is an improvement over nvdimm
that pre-created "seed" devices that tended to confuse users looking to
determine which devices are active and which are idle.
Recall that the major change that CXL brings over previous persistent
memory architectures is the ability to dynamically define new regions.
Compare that to drivers like 'nfit' where the region configuration is
statically defined by platform firmware.
Regions are created as a child of a root decoder that encompasses an
address space with constraints. When created through sysfs, the root
decoder is explicit. When created from an LSA's region structure a root
decoder will possibly need to be inferred by the driver.
Upon region creation through sysfs, a vacant region is created with a
unique name. Regions have a number of attributes that must be configured
before the region can be bound to the driver where HDM decoder program
is completed.
An example of creating a new region:
- Allocate a new region name:
region=$(cat /sys/bus/cxl/devices/decoder0.0/create_pmem_region)
- Create a new region by name:
while
region=$(cat /sys/bus/cxl/devices/decoder0.0/create_pmem_region)
! echo $region > /sys/bus/cxl/devices/decoder0.0/create_pmem_region
do true; done
- Region now exists in sysfs:
stat -t /sys/bus/cxl/devices/decoder0.0/$region
- Delete the region, and name:
echo $region > /sys/bus/cxl/devices/decoder0.0/delete_region

The region provisioning flow involves selecting interleave ways +
granularity settings for a region, and then programming the decoder
topology to meet those constraints, if possible. For example, root
decoders set the minimum interleave ways + granularity for any hosted
regions.
Given decoder programming is not atomic and collisions can occur between
multiple requesting regions userspace will be responsible for conflict
resolution and it needs these attributes to make those decisions.

The region provisioning flow will roughly follow a sequence of:
1/ Allocate DPA to a set of decoders
2/ Allocate HPA to a region
3/ Associate decoders with a region and validate that the DPA allocations
and topologies match the parameters of the region.
For now, this change (step 1) arranges for DPA capacity to be allocated
and deleted from non-committed decoders based on the decoder's mode /
partition selection. Capacity is allocated from the lowest DPA in the
partition and any 'pmem' allocation blocks out all remaining ram
capacity in its 'skip' setting. DPA allocations are enforced in decoder
instance order. I.e. decoder N + 1 always starts at a higher DPA than
instance N, and deleting allocations must proceed from the
highest-instance allocated decoder to the lowest.

Recall that the Device Physical Address (DPA) space of a CXL Memory
Expander is potentially partitioned into a volatile and persistent
portion. A decoder maps a Host Physical Address (HPA) range to a DPA
range and that translation depends on the value of all previous (lower
instance number) decoders before the current one.
In preparation for allowing dynamic provisioning of regions, decoders
need an ABI to indicate which DPA partition a decoder targets. This ABI
needs to be prepared for the possibility that some other agent committed
and locked a decoder that spans the partition boundary.
Add 'decoderX.Y/mode' to endpoint decoders that indicates which
partition 'ram' / 'pmem' the decoder targets, or 'mixed' if the decoder
currently spans the partition boundary.

The per-device CDAT data provides performance data that is relevant for
mapping which CXL devices can participate in which CXL ranges by QTG
(QoS Throttling Group) (per ECN: CXL 2.0 CEDT CFMWS & QTG_DSM) [1]. The
QTG association specified in the ECN is advisory. Until the
cxl_acpi driver grows support for invoking the QTG _DSM method the CDAT
data is only of interest to userspace that may need it for debug
purposes.
Search the DOE mailboxes available, query CDAT data, cache the data and
make it available via a sysfs binary attribute per endpoint at:
/sys/bus/cxl/devices/endpointX/CDAT
...similar to other ACPI-structured table data in
/sys/firmware/ACPI/tables. The CDAT is relative to 'struct cxl_port'
objects since switches in addition to endpoints can host a CDAT
instance. Switch CDAT support is not implemented.
This does not support table updates at runtime. It will always provide
whatever was there when first cached. It is also the case that table
updates are not expected outside of explicit DPA address map affecting
commands like Set Partition with the immediate flag set. Given that the
driver does not support Set Partition with the immediate flag set there
is no current need for update support.

Several on-running cleanup efforts dominate this time, plus the DMA
safety alignment issue identified due to improved understanding of
the restrictions as a result of Catalin Marinas' efforts in that area.
One immutable branch in here due to MFD and SPMI elements needed for
the qcom-rradc driver.
Device support
* bmi088
- Add support for bmi085 (accelerometer part of IMU)
- Add support for bmi090l (accelerometer part of IMU)
* mcp4922
- Add support for single channel device MCP4921
* rzg2l-adc
- Add compatible and minor tweaks to support RZ/G2UL ADC
* sca3300
- Add support for scl3300 including refactoring driver to support
multiple device types and cleanup noticed whilst working on driver.
* spmi-rradc
- New driver for Qualcomm SPMI Round Robin ADC including necessary
additional utility functions in SPMI core and related MFD driver.
* ti-dac55781
- Add compatible for DAC121C081 which is very similar to existing parts.
Features
* core
- Warn on iio_trigger_get() on an unregistered IIO trigger.
* bma400
- Triggered buffer support
- Activity and step counting
- Misc driver improvements such as devm and header ordering
* cm32181
- Add PM support.
* cros_ec
- Sensor location support
* sx9324
- Add precharge resistor setting
- Add internal compensation resistor setting
- Add CS idle/sleep mode.
* sx9360
- Add precharge resistor setting
* vl53l0x
- Handle reset GPIO, regulator and relax handling of irq type.
Cleanup and minor fixes:
Treewide changes
- Cleanup of error handling in remove functions in many drivers.
- Update dt-binding maintainers for a number of ADI bindings.
- Several sets of conversion of drivers from device tree specific to
generic device properties. Includes fixing up various related
header and Kconfig issues.
- Drop include of of.h from iio.h and fix up drivers that need to include
it directly.
- More moves of clusters of drivers into appropriate IIO_XXX namespaces.
- Tree wide fix of a long running bug around DMA safety requirements.
IIO was using __cacheline_aligned to pad iio_priv() structures. This
worked for a long time by coincidence, but correct alignment is
ARCH_KMALLOC_MINALIGN. As there is activity around this area, introduce
an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather
than every driver in future. Note, there have been no reports of this
bug in the wild, and it may not happen on any platforms supported by
upstream, so no rush to backport these fixes.
Other cleanup
* core
- Switch to ida_alloc()/free()
- Drop unused iio_get_time_res()
- Octal permissions and DEVICE_ATTR_* macros.
- Cleanup bared unsigned usage.
* MAINTAINERS
- Add include/dt-bindings/iio/ to the main IIO entry.
* ad5380
- Comment syntax fix.
* ad74413r
- Call to for_each_set_bit_from(), with from value as 0 replaced.
* ad7768-1
- Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core.
* adxl345
- Fix wrong address in dt-binding example.
* adxl367
- Drop extra update of FIFO watermark.
* at91-sama5d2
- Limit requested watermark to the hwfifo size.
* bmg160, bme680
- Typos
* cio-dac
- Switch to iomap rather than direct use of ioports
* kxsd9
- Replace CONFIG_PM guards with new PM macros that let the compiler
cleanly remove the unused code and structures when !CONFIG_PM
* lsm6dsx
- Use new pm_sleep_ptr() and EXPORT_SIMPLE_DEV_PM_OPS(). Then move
to Namespace.
* meson_saradc - general cleanup.
- Avoid attaching resources to iio_dev->dev
- Use same struct device for all error messages
- Convert to dev_err_probe() and use local struct device *dev to
reduce code complexity.
- Use devm_clk_get_optional() instead of hand rolling.
- Use regmap_read_poll_timeout() instead of hand rolling.

IIO new device support, features and minor fixes for 5.20
Several on-running cleanup efforts dominate this time, plus the DMA
safety alignment issue identified due to improved understanding of
the restrictions as a result of Catalin Marinas' efforts in that area.
One immutable branch in here due to MFD and SPMI elements needed for
the qcom-rradc driver.
Device support
* bmi088
- Add support for bmi085 (accelerometer part of IMU)
- Add support for bmi090l (accelerometer part of IMU)
* mcp4922
- Add support for single channel device MCP4921
* rzg2l-adc
- Add compatible and minor tweaks to support RZ/G2UL ADC
* sca3300
- Add support for scl3300 including refactoring driver to support
multiple device types and cleanup noticed whilst working on driver.
* spmi-rradc
- New driver for Qualcomm SPMI Round Robin ADC including necessary
additional utility functions in SPMI core and related MFD driver.
* ti-dac55781
- Add compatible for DAC121C081 which is very similar to existing parts.
Features
* core
- Warn on iio_trigger_get() on an unregistered IIO trigger.
* bma400
- Triggered buffer support
- Activity and step counting
- Misc driver improvements such as devm and header ordering
* cm32181
- Add PM support.
* cros_ec
- Sensor location support
* sx9324
- Add precharge resistor setting
- Add internal compensation resistor setting
- Add CS idle/sleep mode.
* sx9360
- Add precharge resistor setting
* vl53l0x
- Handle reset GPIO, regulator and relax handling of irq type.
Cleanup and minor fixes:
Treewide changes
- Cleanup of error handling in remove functions in many drivers.
- Update dt-binding maintainers for a number of ADI bindings.
- Several sets of conversion of drivers from device tree specific to
generic device properties. Includes fixing up various related
header and Kconfig issues.
- Drop include of of.h from iio.h and fix up drivers that need to include
it directly.
- More moves of clusters of drivers into appropriate IIO_XXX namespaces.
- Tree wide fix of a long running bug around DMA safety requirements.
IIO was using __cacheline_aligned to pad iio_priv() structures. This
worked for a long time by coincidence, but correct alignment is
ARCH_KMALLOC_MINALIGN. As there is activity around this area, introduce
an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather
than every driver in future. Note, there have been no reports of this
bug in the wild, and it may not happen on any platforms supported by
upstream, so no rush to backport these fixes.
Other cleanup
* core
- Switch to ida_alloc()/free()
- Drop unused iio_get_time_res()
- Octal permissions and DEVICE_ATTR_* macros.

- Use new pm_sleep_ptr() and EXPORT_SIMPLE_DEV_PM_OPS(). Then move
to Namespace.
* meson_saradc - general cleanup.
- Avoid attaching resources to iio_dev->dev
- Use same struct device for all error messages
- Convert to dev_err_probe() and use local struct device *dev to
reduce code complexity.

Enabling and disabling PEC for PMBus devices is currently only supported
with a debugfs attribute, which requires debugfs to be enabled and is
thus less than perfect. Take the lm90 driver as example and add a 'pec'
attribute to the I2C device if both the I2C adapter and the PMBus device
support it. Remove the now obsolete 'pec' attribute from debugfs.

The main issue this driver addresses is that a USB hub needs to be
powered before it can be discovered. For discrete onboard hubs (an
example for such a hub is the Realtek RTS5411) this is often solved
by supplying the hub with an 'always-on' regulator, which is kind
of a hack. Some onboard hubs may require further initialization
steps, like changing the state of a GPIO or enabling a clock, which
requires even more hacks. This driver creates a platform device
representing the hub which performs the necessary initialization.
Currently it only supports switching on a single regulator, support
for multiple regulators or other actions can be added as needed.
Different initialization sequences can be supported based on the
compatible string.
Besides performing the initialization the driver can be configured
to power the hub off during system suspend. This can help to extend
battery life on battery powered devices which have no requirements
to keep the hub powered during suspend. The driver can also be
configured to leave the hub powered when a wakeup capable USB device
is connected when suspending, and power it off otherwise.
Technically the driver consists of two drivers, the platform driver
described above and a very thin USB driver that subclasses the
generic driver. The purpose of this driver is to provide the platform
driver with the USB devices corresponding to the hub(s) (a hub
controller may provide multiple 'logical' hubs, e.g. one to support
USB 2.0 and another for USB 3.x).

Expose the device state through an attribute in sysfs and allow to
change it. This is to stop and shutdown a QAT device in order to change
its configuration.
The state attribute has been added to a newly created `qat` attribute
group which will contain all _QAT specific_ attributes.
The logic that implements the sysfs entries is part of a new file,
adf_sysfs.c. This exposes an entry point to allow the driver to create
attributes.
The function that creates the sysfs attributes is called from the probe
function of the driver and not in the state machine init function to
allow the change of states even if the device is in the down state.
In order to restore the device configuration between a transition from
down to up, the function that configures the devices has been abstracted
into the HW data structure.
The `state` attribute is only exposed for qat_4xxx devices.

Pss is the sum of the sizes of clean and dirty private pages, and the
proportional sizes of clean and dirty shared pages:
Private = Private_Dirty + Private_Clean
Shared_Proportional = Shared_Dirty_Proportional + Shared_Clean_Proportional
Pss = Private + Shared_Proportional
The Shared*Proportional fields are not present in smaps, so it is not
always possible to determine how much of the Pss is from dirty pages and
how much is from clean pages. This information can be useful for
measuring memory usage for the purpose of optimisation, since clean pages
can usually be discarded by the kernel immediately while dirty pages
cannot.
The smaps routines in the kernel already have access to this data, so add
a Pss_Dirty to show it to userspace. Pss_Clean is not added since it can
be calculated from Pss and Pss_Dirty.

Add a driver providing a tablet-mode switch input device for Microsoft
Surface devices using the Surface Aggregator KIP subsystem (to manage
detachable peripherals) or POS subsystem (to obtain device posture
information).
The KIP (full name unknown, abbreviation found through reverse
engineering) subsystem is used on the Surface Pro 8 and Surface Pro X to
manage the keyboard cover. Among other things, it provides information
on the positioning (posture) of the cover (closed, laptop-style,
detached, folded-back, ...), which can be used to implement an input
device providing the SW_TABLET_MODE event. Similarly, the POS (posture
information) subsystem provides such information on the Surface Laptop
Studio, with the difference being that the keyboard is not detachable.
As implementing the tablet-mode switch for both subsystems is largely
similar, the driver proposed in this commit, in large, acts as a generic
tablet mode switch driver framework for the Surface Aggregator Module.
Specific implementations using this framework are provided for the KIP
and POS subsystems, adding tablet-mode switch support to the
aforementioned devices.
A few more notes on the Surface Laptop Studio:
A peculiarity of the Surface Laptop Studio is its "slate/tent" mode
(symbolized: user> _/\). In this mode, the screen covers the keyboard
but leaves the touchpad exposed. This is essentially a mode in-between
tablet and laptop, and it is debatable whether tablet-mode should be
enabled in this mode. We therefore let the user decide this via a module
parameter.
In particular, tablet-mode may bring up the on-screen touch keyboard
more easily, which would be desirable in this mode. However, some
user-space software currently also decides to disable keyboard and, more
importantly, touchpad input, while the touchpad is still accessible in
the "slate/tent" mode. Furthermore, this mode shares its identifier with
"slate/flipped" mode where the screen is flipped 180° and the keyboard
points away from the user (symbolized: user> /_). In this mode we would
like to enable auto-rotation, something that user-space software may
only do when tablet-mode is enabled. We therefore default to the
slate-mode enabling the tablet-mode switch.

Stale Data.
They are a class of MMIO-related weaknesses which can expose stale data
by propagating it into core fill buffers. Data which can then be leaked
using the usual speculative execution methods.
Mitigations include this set along with microcode updates and are
similar to MDS and TAA vulnerabilities: VERW now clears those buffers

All the USB Type-C Connector Class devices are protected, so
the drivers can not directly access them. This will adds a
few helpers that can be used to link the ports and partners
to the correct USB Power Delivery objects.
For ports a new optional sysfs attribute file is also added
that can be used to select the USB Power Delivery
capabilities that the port will advertise to the partner.

Introducing a small device class for USB Power Delivery.
The idea with it is that we do not mix any more USB Power
Delivery information into the USB Type-C connectors only.
This separation will make it possible to register USB Power
Delivery devices also from other places, for example from
USB Type-C Bridges (see USB Type-C Bridge Specification).
The device class will not always deal with only the messages
and objects that were negotiated with the partner, but
instead messages and objects that can be used in the
negotiation. That allows the USB PD devices to be shared and
reconfigured. The ports can decide which objects are to be
advertised to the partner before the contract is negotiated.
It is also possible to allow the user space to make that
decision if needed.

In some cases the port of an hub needs to be disabled or switched off
and on again. E.g. when the connected device needs to be re-enumerated.
Or it needs to be explicitly disabled while the rest of the usb tree
stays working.
For this purpose this patch adds an sysfs switch to enable/disable the
port on any hub. In the case the hub is supporting power switching, the
power line will be disabled to the connected device.
When the port gets disabled, the associated device gets disconnected and
removed from the logical usb tree. No further device will be enumerated
on that port until the port gets enabled again.

The {dma|pio}_mode sysfs files are incorrectly documented as having a
list of the supported DMA/PIO transfer modes, while the corresponding
fields of the *struct* ata_device hold the transfer mode IDs, not masks.
To match these docs, the {dma|pio}_mode (and even xfer_mode!) sysfs
files are handled by the ata_bitfield_name_match() macro which leads to
reading such kind of nonsense from them:
$ cat /sys/class/ata_device/dev3.0/pio_mode
XFER_UDMA_7, XFER_UDMA_6, XFER_UDMA_5, XFER_UDMA_4, XFER_MW_DMA_4,
XFER_PIO_6, XFER_PIO_5, XFER_PIO_4, XFER_PIO_3, XFER_PIO_2, XFER_PIO_1,
XFER_PIO_0
Using the correct ata_bitfield_name_search() macro fixes that:
$ cat /sys/class/ata_device/dev3.0/pio_mode
XFER_PIO_4
While fixing the file documentation, somewhat reword the {dma|pio}_mode
file doc and add a note about being mostly useful for PATA devices to
the xfer_mode file doc...

Extend the MAX10 BMC Secure Update driver to provide sysfs files to
expose the 128 bit code signing key (CSK) cancellation vectors. These use
the standard bitmap list format (e.g. 1,2-6,9).
Each CSK is assigned an ID, a number between 0-127, during the signing
process. CSK ID cancellation information is stored in 128-bit fields in
write-once locations in flash. The cancellation of a CSK can be used
to prevent the card from being rolled back to older images that were
signed with a CSK that is now cancelled.

Create a sub-driver for the FPGA Card BMC in order to support secure
updates. This patch creates the Max10 BMC Secure Update driver and
provides sysfs files for displaying the root entry hashes (REH) for the
FPGA static region (SR), the FPGA Partial Reconfiguration (PR) region,
and the card BMC.
The Intel MAX10 BMC Root of Trust (RoT) requires that all BMC Nios firmware
and FPGA images are authenticated using ECDSA before loading and executing
on the card. Code Signing Keys (CSK) are used to sign images. CSKs are
signed by a root key. The root entry hash is created from the root public
key.
The RoT provides authentication by storing an REH bitstream to a write-once
location. Image signatures are verified against the hash.

Here is the set of driver core changes for 5.19-rc1.
Note, I'm not really happy with this pull request as-is, see below for
details, but overall this is all good for everything but a small set of
systems, which we have a fix for already.
Lots of tiny driver core changes and cleanups happened this cycle,
but the two major things were:
- firmware_loader reorganization and additions including the
ability to have XZ compressed firmware images and the ability
for userspace to initiate the firmware load when it needs to,
instead of being always initiated by the kernel. FPGA devices
specifically want this ability to have their firmware changed
over the lifetime of the system boot, and this allows them to
work without having to come up with yet-another-custom-uapi
interface for loading firmware for them.
- physical location support added to sysfs so that devices that
know this information, can tell userspace where they are
located in a common way. Some ACPI devices already support
this today, and more bus types should support this in the
future.
Smaller changes included:
- driver_override api cleanups and fixes
- error path cleanups and fixes
- get_abi script fixes
- deferred probe timeout changes.
It's that last change that I'm the most worried about. It has been
reported to cause boot problems for a number of systems, and I have a
tested patch series that resolves this issue. But I didn't get it
merged into my tree before 5.18-final came out, so it has not gotten any
linux-next testing.
I'll send the fixup patches (there are 2) as a follow-on series to this
pull request if you want to take them directly, _OR_ I can just revert
the probe timeout changes and they can wait for the next -rc1 merge
cycle. Given that the fixes are tested, and pretty simple, I'm leaning
toward that choice. Sorry this all came at the end of the merge window,
I should have resolved this all 2 weeks ago, that's my fault as it was
in the middle of some travel for me.
All have been tested in linux-next for weeks, with no reported issues
other than the above-mentioned boot time outs.

- PHY driver tree merge with new drivers and small updates to

Here is the "big" set of USB and Thunderbolt driver changes for
5.18-rc1. For the most part it's been a quiet development cycle for the
USB core, but there are the usual "hot spots" of development activity.
Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused

Pull USB / Thunderbolt updates from Greg KH:
"Here is the "big" set of USB and Thunderbolt driver changes for
5.18-rc1. For the most part it's been a quiet development cycle for
the USB core, but there are the usual "hot spots" of development
activity.
Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes.
It seems this driver will never be finished given that the IP core
is showing up in zillions of new devices and each implementation
decides to do something different with it...
- uvc gadget driver updates as more devices start to use and rely on
this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.
All of these have been in linux-next for weeks with no reported
problems"

When Gaudi device is secured the monitors data in the configuration
space is blocked from PCI access.
As we need to enable user to get sync-manager monitors registers when
debugging, this patch adds a debugfs that dumps the information to a
binary file (blob).
When a root user will trigger the dump, the driver will send request to
the f/w to fill a data structure containing dump of all monitors
registers.

MHI Host
--------
Support for new modems:
- Foxconn Cinterion MV32-WA/MV32-WB based on SDX62/SDX65
- Telit FN980 v1 based on SDX55
- Telit FN990 based on SDX65
- Foxconn T99W373/T99W368 based on SDX62/SDX65
Core changes:
- During the recycle of event ring elements, compute the ctxt_wp based on the
local cached value instead of reading from shared memory. This is to prevent
the possible corruption of the ctxt_wp as some of the endpoint devices could
modify the value in shared memory.
- Add sysfs support for resetting the endpoint based on the MHI spec. The MHI
spec allows the host to hard reset the device in the case of an unrecoverable
error and all other reset mechanisms have failed.
- During MHI shutdown, wait for the endpoint device to enter the ready state
post reset before proceeding. This is to avoid a possible race where host
would remove the interrupt handler and device will send ready state
interrupt, resulting in IOMMU fault.
- Bail out updating the MHI register if the read has failed during
read/modify/write.
- Use mhi_write_reg() instead of mhi_write_reg_field() for writing the whole
register fields in mhi_init_mmio().
MAINTAINERS change:
- Since Qualcomm has moved the email domain for its employess from codeaurora
domain to quicinc, update the same for Hemant.

The x86 Chromebooks have the ChromeOS ACPI device. This driver attaches
to the ChromeOS ACPI device and exports the values reported by ACPI in a
sysfs directory. This data isn't present in ACPI tables when read
through ACPI tools, hence a driver is needed to do it. The driver gets
data from firmware using the ACPI component of the kernel. The ACPI values
are presented in string form (numbers as decimal values) or binary
blobs, and can be accessed as the contents of the appropriate read only
files in the standard ACPI device's sysfs directory tree. This data is
consumed by the ChromeOS user space.

IMA may verify a file's integrity against a "good" value stored in the
'security.ima' xattr or as an appended signature, based on policy. When
the "good value" is stored in the xattr, the xattr may contain a file
hash or signature. In either case, the "good" value is preceded by a
header. The first byte of the xattr header indicates the type of data
- hash, signature - stored in the xattr. To support storing fs-verity
signatures in the 'security.ima' xattr requires further differentiating
the fs-verity signature from the existing IMA signature.
In addition the signatures stored in 'security.ima' xattr, need to be
disambiguated. Instead of directly signing the fs-verity digest, a new
signature format version 3 is defined as the hash of the ima_file_id
structure, which identifies the type of signature and the digest.
The IMA policy defines "which" files are to be measured, verified, and/or
audited. For those files being verified, the policy rules indicate "how"
the file should be verified. For example to require a file be signed,
the appraise policy rule must include the 'appraise_type' option.
appraise_type:= [imasig] | [imasig|modsig] | [sigv3]
where 'imasig' is the original or signature format v2 (default),
where 'modsig' is an appended signature,
where 'sigv3' is the signature format v3.
The policy rule must also indicate the type of digest, if not the IMA
default, by first specifying the digest type:
digest_type:= [verity]
The following policy rule requires fsverity signatures. The rule may be
constrained, for example based on a fsuuid or LSM label.
appraise func=BPRM_CHECK digest_type=verity appraise_type=sigv3

Permit fsverity's file digest (a hash of struct fsverity_descriptor) to
be included in the IMA measurement list, based on the new measurement
policy rule 'digest_type=verity' option.
To differentiate between a regular IMA file hash from an fsverity's
file digest, use the new d-ngv2 format field included in the ima-ngv2
template.
The following policy rule requires fsverity file digests and specifies
the new 'ima-ngv2' template, which contains the new 'd-ngv2' field. The
policy rule may be constrained, for example based on a fsuuid or LSM
label.

When ACPI table includes _PLD fields for a device, create a new
directory (physical_location) in sysfs to share _PLD fields.
Currently without PLD information, when there are multiple of same
devices, it is hard to distinguish which device corresponds to which
physical device at which location. For example, when there are two Type
C connectors, it is hard to find out which connector corresponds to the
Type C port on the left panel versus the Type C port on the right panel.
With PLD information provided, we can determine which specific device at
which location is doing what.
_PLD output includes much more fields, but only generic fields are added
and exposed to sysfs, so that non-ACPI devices can also support it in
the future. The minimal generic fields needed for locating a device are
the following.
- panel
- vertical_position
- horizontal_position
- dock
- lid

The main issue this driver addresses is that a USB hub needs to be
powered before it can be discovered. For discrete onboard hubs (an
example for such a hub is the Realtek RTS5411) this is often solved
by supplying the hub with an 'always-on' regulator, which is kind
of a hack. Some onboard hubs may require further initialization
steps, like changing the state of a GPIO or enabling a clock, which
requires even more hacks. This driver creates a platform device
representing the hub which performs the necessary initialization.
Currently it only supports switching on a single regulator, support
for multiple regulators or other actions can be added as needed.
Different initialization sequences can be supported based on the
compatible string.
Besides performing the initialization the driver can be configured
to power the hub off during system suspend. This can help to extend
battery life on battery powered devices which have no requirements
to keep the hub powered during suspend. The driver can also be
configured to leave the hub powered when a wakeup capable USB device
is connected when suspending, and power it off otherwise.
Technically the driver consists of two drivers, the platform driver
described above and a very thin USB driver that subclasses the
generic driver. The purpose of this driver is to provide the platform
driver with the USB devices corresponding to the hub(s) (a hub
controller may provide multiple 'logical' hubs, e.g. one to support
USB 2.0 and another for USB 3.x).
Note: the current series only supports hubs connected directly to
a root hub, support for other configurations could be added if
needed.
