A root node is required to apply DT overlays. A root node is usually
present after commit 7b937cc243e5 ("of: Create of_root if no dtb
provided by firmware"), except for on arm64 systems booted with ACPI
tables. In that case, the root node is intentionally not populated
because it would "allow DT devices to be instantiated atop an ACPI base
system"[1].
Introduce an OF function that skips the kunit test if the root node
isn't populated. Limit the test to when both CONFIG_ARM64 and
CONFIG_ACPI are set, because otherwise the lack of a root node is a bug.
Make the function private and take a kunit test parameter so that it
can't be abused to test for the presence of the root node in non-test
code.
Use this function to skip tests that require the root node. Currently
that's the DT tests and any tests that apply overlays.

Got following report when doing overlay_test:
OF: ERROR: memory leak, expected refcount 1 instead of 2,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /kunit-test
OF: ERROR: memory leak before free overlay changeset, /kunit-test
In of_overlay_apply_kunit_cleanup(), the "np" should be associated with
fake instead of test to call of_node_put(), so the node is put before
the overlay is removed.
It also fix the following memory leaks:

scripts/Makefile.lib is included not only from scripts/Makefile.build
but also from scripts/Makefile.{modfinal,package,vmlinux,vmlinux_o},
where DT build rules are not required.
Split the DT build rules out to scripts/Makefile.dtbs, and include it
only when necessary.
While I was here, I added $(DT_TMP_SCHEMA) as a prerequisite of
$(multi-dtb-y).

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The core clk framework is left largely untouched this time around
except for support for the newly ratified DT property
'assigned-clock-rates-u64'.
I'm much more excited about the support for loading DT overlays from
KUnit tests so that we can test how the clk framework parses DT nodes
during clk registration. The clk framework has some places that are
highly DeviceTree dependent so this charts the path to extend the
KUnit tests to cover even more framework code in the future. I've got
some more tests on the list that use the DT overlay support, but they
uncovered issues with clk unregistration that I'm still working on
fixing.
Outside the core, the clk driver update pile is dominated by Qualcomm
and Renesas SoCs, making it fairly usual. Looking closer, there are
fixes for things all over the place, like adding missing clk
frequencies or moving defines for the number of clks out of DT binding
headers into the drivers. There are even conversions of DT bindings to
YAML and migration away from strings to describe clk topology. Overall
it doesn't look unusual so I expect the new drivers to be where we'll
have fixes in the coming weeks.
Core:
- KUnit tests for clk registration and fixed rate basic clk type
- A couple more devm helpers, one consumer and one provider
- Support for assigned-clock-rates-u64
New Drivers:
- Camera, display and GPU clocks on Qualcomm SM4450
- Camera clocks on Qualcomm SM8150
- Rockchip rk3576 clks
- Microchip SAM9X7 clks
- Renesas RZ/V2H(P) (R9A09G057) clks
Updates:
- Mark a bunch of struct freq_tbl const to reduce .data usage
- Add Qualcomm MSM8226 A7PLL and Regera PLL support
- Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
Trion, as they do differ
- A number of fixes to the Qualcomm SM8550 display clock driver
- Fold Qualcomm SM8650 display clock driver into SM8550 one
- Add missing clocks and GDSCs needed for audio on Qualcomm MSM8998
- Add missing USB MP resets, GPLL9, and QUPv3 DFS to Qualcomm SC8180X
- Fix sdcc clk frequency tables on Qualcomm SC8180X
- Drop the Qualcomm SM8150 gcc_cpuss_ahb_clk_src
- Mark Qualcomm PCIe GDSCs as RET_ON on sm8250 and sm8540 to avoid
them turning off during suspend
- Use the HW_CTRL mechanism on Qualcomm SM8550 video clock controller
GDSCs
- Get rid of CLK_NR_CLKS defines in Rockchip DT binding headers
- Some fixes for Rockchip rk3228 and rk3588

test managed APIs work correctly and can be relied upon to provide tests
with fake platform devices and device nodes via overlays compiled into
the kernel image.

Add test managed wrappers for of_overlay_apply() that automatically
removes the overlay when the test is finished. This API is intended for
use by KUnit tests that test code which relies on 'struct device_node's
and of_*() APIs.
KUnit tests will call of_overlay_apply_kunit() to load an overlay that's
been built into the kernel image. When the test is complete, the overlay
will be removed.
This has a few benefits:
1) It keeps the tests hermetic because the overlay is removed when the
test is complete. Tests won't even be aware that an overlay was
loaded in another test.
2) The overlay code can live right next to the unit test that loads it.
The overlay and the unit test can be compiled into one kernel module
if desired.
3) We can test different device tree configurations by loading
different overlays. The overlays can be written for a specific test,
and there can be many of them loaded per-test without needing to jam
all possible combinations into one DTB.
4) It also allows KUnit to test device tree dependent code on any
architecture, not just UML. This allows KUnit tests to test
architecture specific device tree code.
There are some potential pitfalls though. Test authors need to be
careful to not overwrite properties in the live tree. The easiest way to
do this is to add and remove nodes with a 'kunit-' prefix, almost
guaranteeing that the same node won't be present in the tree loaded at
boot.

We'd like to apply overlays to the root node in KUnit so we can test
platform devices created as children of the root node.
On some architectures (powerpc), the root node isn't marked with
OF_POPULATED_BUS. If an overlay tries to modify the root node on these
platforms it will fail, while on other platforms, such as ARM, it will
succeed. This is because the root node is marked with OF_POPULATED_BUS
by of_platform_default_populate_init() calling
of_platform_default_populate() with NULL as the first argument.
Loosen the requirement here so that platform devices can be created for
nodes created as children of the root node via DT overlays even if the
platform bus wasn't populated for the root node.

Currently of_numa_parse_memory_nodes() returns 0 if no "memory" node in
device tree contains "numa-node-id" property. This makes of_numa_init()
to return "success" despite no NUMA nodes were actually parsed and set up.
arch_numa workarounds this by returning an error if numa_nodes_parsed is
empty.
numa_memblks however would WARN() in such case and since it will be used
by arch_numa shortly, such warning is not desirable.
Make sure of_numa_init() returns -EINVAL when no NUMA node information was
found in the device tree.

The description of the function now explicitly states that it's
an *exact* match for the given string (i.e. not a submatch). It also
better states all the possible return values.

__free() provides a scoped of_node_put() functionality to put the
device_node automatically, and we don't need to call of_node_put()
directly. Let's simplify the code a bit with the use of __free().

The members "start" and "end" of struct resource are of type
"resource_size_t" which can be 32bit wide.
Values read from OF however are always 64bit wide.
Avoid silently truncating the value and instead return an error value.
This can happen on real systems when the DT was created for a
PAE-enabled kernel and a non-PAE kernel is actually running.
For example with an arm defconfig and "qemu-system-arm -M virt".

An 'msi-parent' property with a single entry and no accompanying
'#msi-cells' property is considered the legacy definition as opposed
to its definition after being expanded with commit 126b16e2ad98
("Docs: dt: add generic MSI bindings"). However, the legacy
definition is completely compatible with the current definition and,
since of_phandle_iterator_next() tolerates missing and present-but-
zero *cells properties since commit e42ee61017f5 ("of: Let
of_for_each_phandle fallback to non-negative cell_count"), there's no
need anymore to special case the legacy definition in
of_msi_get_domain().
Indeed, special casing has turned out to be harmful, because, as of
commit 7c025238b47a ("dt-bindings: irqchip: Describe the IMX MU block
as a MSI controller"), MSI controller DT bindings have started
specifying '#msi-cells' as a required property (even when the value
must be zero) as an effort to make the bindings more explicit. But,
since the special casing of 'msi-parent' only uses the existence of
'#msi-cells' for its heuristic, and not whether or not it's also
nonzero, the legacy path is not taken. Furthermore, the path to
support the new, broader definition isn't taken either since that
path has been restricted to the platform-msi bus.
But, neither the definition of 'msi-parent' nor the definition of
'#msi-cells' is platform-msi-specific (the platform-msi bus was just
the first bus that needed '#msi-cells'), so remove both the special
casing and the restriction. The code removal also requires changing
to of_parse_phandle_with_optional_args() in order to ensure the
legacy (but compatible) use of 'msi-parent' remains supported. This
not only simplifies the code but also resolves an issue with PCI
devices finding their MSI controllers on riscv, as the riscv,imsics
binding requires '#msi-cells=<0>'.

Use of_property_present() to test for property presence rather than
of_find_property(). This is part of a larger effort to remove callers
of of_find_property() and similar functions. of_find_property() leaks
the DT struct property and data pointers which is a problem for
dynamically allocated nodes which may be freed.

In aperture_remove_conflicting_pci_devices(), we currently only
call sysfb_disable() on vga class devices. This leads to the
following problem when the pimary device is not VGA compatible:
1. A PCI device with a non-VGA class is the boot display
2. That device is probed first and it is not a VGA device so
sysfb_disable() is not called, but the device resources
are freed by aperture_detach_platform_device()
3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable()
4. NULL pointer dereference via sysfb_disable() since the resources
have already been freed by aperture_detach_platform_device() when
it was called by the other device.
Fix this by passing a device pointer to sysfb_disable() and checking
the device to determine if we should execute it or not.
v2: Fix build when CONFIG_SCREEN_INFO is not set
v3: Move device check into the mutex
Drop primary variable in aperture_remove_conflicting_pci_devices()
Drop __init on pci sysfb_pci_dev_is_enabled()

We no longer have a notion of partially-initialised fwspecs existing,
and we also no longer need to use an iommu_ops pointer to return status
to of_dma_configure(). Clean up the remains of those, which lends itself
to clarifying the logic around the dma_range_map allocation as well.

The str_array parameter has no reason to be an un-const array.
Indeed, elements of the 'str_array' array are not changed by the code.
Constify the 'str_array' array parameter.
With this const qualifier added, the following construction is allowed:
static const char * const tab_str[] = { "string1", "string2" };
of_changeset_add_prop_string_array(..., tab_str, ARRAY_SIZE(tab_str));

Once again, we've broken PASEMI Nemo boards with its incomplete
"interrupt-map" translations. Commit 935df1bd40d4 ("of/irq: Factor out
parsing of interrupt-map parent phandle+args from of_irq_parse_raw()")
changed the behavior resulting in the existing work-around not taking
effect. Rework the work-around to just skip parsing "interrupt-map" up
front by using the of_irq_imap_abusers list.

Commit d976c6f4b32c ("of: property: Add fw_devlink support for
interrupt-map property") tried to do what it says on the tin,
but failed on a couple of points:
- it confuses bytes and cells. Not a huge deal, except when it
comes to pointer arithmetic
- it doesn't really handle anything but interrupt-maps that have
their parent #address-cells set to 0
The combinations of the two leads to some serious fun on my M1
box, with plenty of WARN-ON() firing all over the shop, and
amusing values being generated for interrupt specifiers.
Having 2 versions of parsing code for "interrupt-map" was a bad
idea. Now that the common parsing parts have been refactored
into of_irq_parse_imap_parent(), rework the code here to use it
instead and fix the pointer arithmetic.
Note that the dependency will be a bit different than the original code
when the interrupt-map points to another interrupt-map. In this case,
the original code would resolve to the final interrupt controller. Now
the dependency is the parent interrupt-map (which itself should have a
dependency to the parent). It is possible that a node with an
interrupt-map has no driver.

of_irq_parse_raw()
Factor out the parsing of interrupt-map interrupt parent phandle and its
arg cells to a separate function, of_irq_parse_imap_parent(), so that it
can be used in other parsing scenarios (e.g. fw_devlink).
There was a refcount leak on non-matching entries when iterating thru
"interrupt-map" which is fixed.

99a741aa7a2d ("i2c: mux: gpio: remove support for class-based device
instantiation") removed the last call to i2c_mux_add_adapter() with a
non-null class argument. Therefore the class argument can be removed.
Note: Class-based device instantiation is a legacy mechanism which
shouldn't be used in new code, so we can rule out that this argument
may be needed again in the future.

Juggling start, end, and size values for a range is somewhat redundant
and a little hard to follow. Consolidate down to just using inclusive
start and end, which saves us worrying about size overflows for full
64-bit ranges (note that passing a potentially-overflowed value through
to arch_setup_dma_ops() is benign for all current implementations, and
this is working towards removing that anyway).

The fixup adding 1 to the dma-ranges size may have been for the benefit
of some early AMD Seattle DTs, or may have merely been a just-in-case,
but either way anyone who might have deserved to get the message has
hopefully seen the warning in the 9 years we've had it there. The modern
dma_range_map mechanism should happily handle odd-sized ranges with no
ill effect, so there's little need to care anyway now. Clean it up.

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
