Some of the PCI host controllers (such as generic PCI host controller)
use "interrupt-map" DT property to describe the mapping between PCI
endpoints and PCI interrupt pins. This is the only case where the
interrupts are not described in DT.
Currently, there is no fw_devlink created based on "interrupt-map"
DT property so interrupt controller is not guaranteed to be probed
before the PCI host controller. This affects every platform where
both PCI host controller and interrupt controllers are probed as
regular platform devices.
This creates fw_devlink between consumers (PCI host controller) and
supplier (interrupt controller) based on "interrupt-map" DT property.

Use __free cleanup handler which ensures that the resource is freed when
it goes out of scope, thus removing the need to manually clean it up
using of_node_put.

Use the relatively new scope based of_node_put() cleanup to simplify
function exit handling. Doing so reduces the chances of forgetting an
of_node_put() and simplifies error paths by avoiding the need for goto
statements.

Here is the "big" set of driver core and kernfs changes for 6.9-rc1.
Nothing all that crazy here, just some good updates that include:
- automatic attribute group hiding from Dan Williams (he fixed up my
horrible attempt at doing this.)
- kobject lock contention fixes from Eric Dumazet
- driver core cleanups from Andy
- kernfs rcu work from Tejun
- fw_devlink changes to resolve some reported issues
- other minor changes, all details in the shortlog
All of these have been in linux-next for a long time with no reported
issues.

IIO Backend support
===================
New approach from Nuno Sa to the problem of reuse of drivers with
IIO devices that are actually the combination of a highspeed chip
and an FPGA core handling the data capture and flows. It will hopefully
also apply to some other split designs. The ad9467 and axi-adi drivers
are converted over to this framework.
New device support
==================
adi,admfm2000
- New driver for this dual microwave down converter.
ams,as73211
- Add support for as7331 UV sensor.
richtek,rtq6056
- Add support for related parts RTQ6053 and RTQ6059
st,lsm6dsx
- Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs)
ti,ads1298
- New driver for this medical ADC.
Features
========
tests
- Unit tests for the gain-time-scale helper library.
bosch,bmi088
- I2C support.
bosh,bmi160
- Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed.
The ID is actually a PCI ID belonging to realtech. No response was received
to earlier attempts to notify them of this.
The manufacturers of some devices have replied to say they will not fix
this incorrect ID. Add the ID and hope it isn't a problem.
bosch,bmi323
- Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150
driver (it appears these parts share a windows driver).
Both drivers perform an ID check that is safe on the other part before
successfully probing.
hid-sensors-als
- Add color temperature and chromaticity support. Note this is a replacement
for the series reverted in 6.8 that correctly handles all the potential
channel combinations.
honeywell,hsc030pa
- Triggered buffer support (after driver cleanup).
honeywell,mprls00025pa
- Improved error handling.
- New DT binding to allow use of part number triplet as provided in data sheet
to specify equivalent of most of the binding more efficiently.
- SPI support.
memsic,mxc4005
- ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023
ti,hdc3020
- Add threshold event support (after some driver cleanup)
veml,vcnl4000
- Switch to high resolution proximity measurement.
Cleanup
=======
Various minor typo fixes and better use of defines etc.
Treewide
- Stop using ACPI_PTR(). The savings in space are small and not worth
the complexity of __maybe_unused of ifdef guards. To avoid use in
new IIO drivers based on copy and paste, clean it out.
- cleanup.h based handling of iio_device_claim_direct_mode()/
iio_device_release_direct_mode() using scope_cond_guard().
In many drivers this is combined with other automated cleanup
to give maximum simplifications.
An initial set of drivers are converted over to this infrastructure.
Tools
- Use rewinddir() instead of seekdir() to return to start of file.
core
- Make iio_bus_type constant.
adi,ad16475
- Use irq_get_trigger_type() instead of opencoding.
adi,ad16480
- Use irq_get_trigger_type() instead of opencoding.
adi,ad-sigma-delta
- Avoid overwriting IRQ flags if provided by firmware.
ams,as73211
- Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially
improve accuracy.
gts-library
- Use a div64_u64() instead of a loop to do a division.
honeywell,mprls00025pa
- Clean up dt-binding doc.
- Drop defaults when DT binding not providing values. Very unlikely
these were useful given they were wrong for vast majority of supported
devices.
- Whitespace cleanup
miramems,da280
- Use i2c_get_match_data() to replace hand rolled ACPI matching code.
semtech,sx9324
- Avoid unnecessary copying of property strings.
st,lsm6dsx
- Improve docs, particularly wrt to making addition of new device
support less noisy.
st,lsm9ds0
- Use dev_err_probe() in all probe() error handling.
- Improved header includes.
- Tidy up termination of ID tables.
ti,ads1014
- Correct upper bound on PGA (wrong value had no actual impact)
ti,afe4403/4404
- devm_ useage to simplify error handling in probe() and allow() remove to
be dropped.
voltage-divider
- Add dt-binding for io-channel-cells to allow such a device to be both
an IIO consumer and IIO producer at the same time.

Similar to the existing "ports" node name, coresight device tree bindings
have added "in-ports" and "out-ports" as standard node names for a
collection of ports.
Add support for these name to of_graph_get_port_parent() so that
remote-endpoint parsing can find the correct parent node for these
coresight ports too.

After commit 4a032827da ("of: property: Simplify of_link_to_phandle()"),
remote-endpoint properties created a fwnode link from the consumer device
to the supplier endpoint. This is a tiny bit inefficient (not buggy) when
trying to create device links or detecting cycles. So, improve this the
same way we improved finding the consumer of a remote-endpoint property.

We have a more accurate function to find the right consumer of a
remote-endpoint property instead of searching for a parent with
compatible string property. So, use that instead. While at it, make the
code to find the consumer a bit more flexible and based on the property
being parsed.

There are cases where an unavailable port is not an error, making this
error message a false-positive. Since commit d56de8c9a1 ("usb: typec:
tcpm: try to get role switch from tcpc fwnode") the role switch is tried
on the port dev first and tcpc fwnode afterwards. If using the latter
bindings getting from port dev fails every time. The kernel log is flooded
with the messages like:
OF: graph: no port node found in /soc@0/bus@42000000/i2c@42530000/usb-typec@50

Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

The driver core now:
- Has the parent device of a supplier pick up the consumers if the
supplier never has a device created for it.
- Ignores a supplier if the supplier has no parent device and will never
be probed by a driver
And already prevents creating a device link with the consumer as a
supplier of a parent.
So, we no longer need to find the "compatible" node of the supplier or
do any other checks in of_link_to_phandle(). We simply need to make sure
that the supplier is available in DT.

When the length of the string is zero of_property_read_string should
return -ENODATA according to the description of the function.
However, of_property_read_string doesn't check prop->length. If
prop->length is zero, return -ENODATA.
Without this patch the following command in u-boot:
fdt set /chosen/node property-name
results in of_property_read_string returning -EILSEQ when attempting to
read property-name. With this patch, it returns -ENODATA as expected.

In the struct supplier_bindings the member 'node_not_dev' is described as
"The consumer node containing the property is never a device.", but that is
inconsistent with the behaviour of the code in of_link_property(), as it
calls of_get_compat_node() that starts parsing for a compatible property
from the node it gets passed to it. The proper behaviour is to start at the
node's parent, so let's do that.
While at it, let's take the opportunity to update the description of the
'node_not_dev' flag, as to clarify its purpose.

This reverts commit cf4b94c853.
Some PHYs pointed to by "phy-handle" will never bind to a driver until a
consumer attaches to it. And when the consumer attaches to it, they get
forcefully bound to a generic PHY driver. In such cases, parsing the
phy-handle property and creating a device link will prevent the consumer
from ever probing. We don't want that. So revert support for
"phy-handle" property until we come up with a better mechanism for
binding PHYs to generic drivers before a consumer tries to attach to it.

Andre reported fw_devlink=on breaking OLPC XO-1.5 [1].
OLPC XO-1.5 is an X86 system that uses a mix of ACPI and OF to populate
devices. The root cause seems to be ISA devices not setting their fwnode
field. But trying to figure out how to fix that doesn't seem worth the
trouble because the OLPC devicetree is very sparse/limited and fw_devlink
only adds the links causing this issue. Considering that there aren't many
users of OF in an X86 system, simply fw_devlink DT support for X86.

remote-endpoint property seems to always come in pairs where two devices
point to each other. So, we can't really tell from DT if there is a
functional probe order dependency between these two devices.
However, there can be other dependencies between two devices that point
to each other with remote-endpoint. This non-remote-endpoint dependency
combined with one of the remote-endpoint dependency can lead to a cyclic
dependency[1].
To avoid this cyclic dependency from incorrectly blocking probes,
fw_devlink needs to be made aware of remote-endpoint dependencies even
though remote-endpoint dependencies by themselves won't affect probe
ordering (because fw_devlink will see the cyclic dependency between
remote-endpoint devices and ignore the dependencies that cause the
cycle).
Also, if a device ever needs to know if a non-probe-blocking
remote-endpoint has finished probing, it can now use the sync_state() to
figure it out.

When CONFIG_OF_IRQ is not defined, it doesn't make sense to parse
interrupts property.
Also, parsing and tracking interrupts property breaks some PPC
devices[1]. But none of the IRQ drivers in PPC seem ready to be
converted to a proper platform (or any bus) driver. So, there's not much
of a point in tracking the interrupts property for CONFIG_PPC. So, let's
stop parsing interrupts for CONFIG_PPC.
