  header files), i915 initial support for RocketLake and some work on

Just use nomap instead of the second call to of_get_flat_dt_prop(). And
change nomap as a bool type due to != NULL operator. Also, correct comment
about node of 'align' -> 'alignment'.

Nicolas Saenz Julienne bda2127827 of: unittest: Use bigger address cells to catch parser regressions
Getting address and size cells for dma-ranges/ranges parsing is tricky
and shouldn't rely on the node's count_cells() method. The function
starts looking for cells on the parent node, as its supposed to work
with device nodes, which doesn't work when input with bus nodes, as
generally done when parsing ranges.

Add test to catch regressions on that specific quirk as developers will
be tempted to edit it out in favor of the default method.

Jiaxun Yang 2f96593ecc of_address: Add bus type match for pci ranges parser
So the parser can be used to parse range property of ISA bus.

As they're all using PCI-like method of range property, there is no need
start a new parser.

Lorenzo Pieralisi 2bcdd8f2c0 of/irq: Make of_msi_map_rid() PCI bus agnostic
There is nothing PCI bus specific in the of_msi_map_rid()
implementation other than the requester ID tag for the input
ID space. Rename requester ID to a more generic ID so that
the translation code can be used by all busses that require
input/output ID translations.

No functional change intended.

Lorenzo Pieralisi a081bd4af4 of/device: Add input id to of_dma_configure()
Devices sitting on proprietary busses have a device ID space that
is owned by the respective bus and related firmware bindings. In order
to let the generic OF layer handle the input translations to
an IOMMU id, for such busses the current of_dma_configure() interface
should be extended in order to allow the bus layer to provide the
device input id parameter - that is retrieved/assigned in bus
specific code and firmware.

Augment of_dma_configure() to add an optional input_id parameter,
leaving current functionality unchanged.

Saravana Kannan fb820b494a of: property: Add device link support for pinctrl-0 through pinctrl-8
Add support for pinctrl-0 through pinctrl-8 explicitly instead of trying
to add support for pinctrl-%d properties.

Of all the pinctrl-* properties in dts files (20322), only 47% (9531)
are pinctrl-%d properties. Of all the pinctrl-%d properties, 99.5%
(9486) are made up of pinctrl-[0-2]. 'pinctrl-8' is the current maximum
found in dts files.

Trying to parse all pinctrl-* properties and checking for pinctrl-%d is
unnecessarily complicated. So, just add support for pinctrl-[0-8] for
now. In the unlikely event we ever exceed pinctrl-8, we can come back
and improve this.

In some cases it's very useful to silently check whether port node exists
at all in a device-tree before proceeding with parsing the graph. The DRM
bridges code is one example of such case where absence of a graph in a
device-tree is a legit condition.

This patch adds of_graph_is_present() which returns true if given
device-tree node contains OF graph port.

Commit 209c65b61d ("drivers/of/of_mdio.c:fix of_mdiobus_register()")
introduced a break of the loop on the premise that a successful
registration should exit the loop. The premise is correct but not to
code, because rc && rc != -ENODEV is just a special error condition,
that means we would exit the loop even with rc == -ENODEV which is
absolutely not correct since this is the error code to indicate to the
MDIO bus layer that scanning should continue.

Fix this by explicitly checking for rc = 0 as the only valid condition
to break out of the loop.

Saravana Kannan bb278b149d of: property: Improve cycle detection when one of the devices is never added
Consider this example where -> means LHS device is a consumer of RHS
device and indentation represents "child of" of the previous device.

Device A -> Device C

Device B -> Device A
	Device C

Without this commit:
1. Device A is added.
2. Device A is added to waiting for supplier list (Device C)
3. Device B is added
4. Device B is linked as a consumer to Device A
5. Device A doesn't probe because it's waiting for Device C to be added.
6. Device B doesn't probe because Device A hasn't probed.
7. Device C will never be added because it's parent hasn't probed.

So, Device A, B and C will be in a probe/add deadlock.

This commit detects this scenario and stops trying to create a device
link between Device A and Device C since doing so would create the
following cycle:
Device A -> Devic C -(parent)-> Device B -> Device A.

With this commit:
1. Device A is added.
3. Device B is added
4. Device B is linked as a consumer to Device A
5. Device A probes.
6. Device B probes because Device A has probed.
7. Device C is added and probed.

Qi Zheng 7536c7e03e of/fdt: Remove redundant kbasename function call
For version 1 to 3 of the device tree, this is the node full
path as a zero terminated string, starting with "/". The
following equation will not hold, since the node name has
been processed in the fdt_get_name().

	*pathp == '/'

For version 16 and later, this is the node unit name only
(or an empty string for the root node). So the above
equation will still not hold.

So the kbasename() is redundant, just remove it.

Saravana Kannan 93d2e4322a of: platform: Batch fwnode parsing when adding all top level devices
The fw_devlink_pause() and fw_devlink_resume() APIs allow batching the
parsing of the device tree nodes when a lot of devices are added. This
will significantly cut down parsing time (as much a 1 second on some
systems). So, use them when adding devices for all the top level device
tree nodes in a system.

While the lookup/initialization code already supports multiple memory
regions per device, the release code will only ever release the first
matching memory region.

Enhance the code to release all matching regions. Each attachment of
a region to a device is uniquely identifiable using a struct device
pointer and a pointer to the memory region's struct reserved_mem.

Nicolas Saenz Julienne 7456427af9 of: property: Do not link to disabled devices
When creating a consumer/supplier relationship between two devices,
make sure the supplier node is actually active. Otherwise this will
create a link relationship that will never be fulfilled. This, in the
worst case scenario, will hang the system during boot.

Note that, in practice, the fact that a device-tree represented
consumer/supplier relationship isn't fulfilled will not prevent devices
from successfully probing.

Nicolas Saenz Julienne ed36557291 of: property: Fix create device links for all child-supplier dependencies
Upon adding a new device from a DT node, we scan its properties and its
children's properties in order to create a consumer/supplier
relationship between the device and the property provider.

That said, it's possible for some of the node's children to be disabled,
which will create links that'll never be fulfilled.

To get around this, use the for_each_available_child_of_node() function
instead of for_each_available_node() when iterating over the node's
children.

Saravana Kannan 8f88fad370 of: property: Don't retry device_link_add() upon failure
When of_link_to_phandle() was implemented initially, there was no way to
tell if device_link_add() was failing because the supplier device hasn't
been parsed yet, hasn't been added yet, the links were creating a cycle,
etc. Some of these were transient errors that'd go away at a later
point.

However, with the current set of improved checks, if device_link_add()
fails, it'll only be for permanent errors like cycles or out-of-memory
errors.

Also, with the addition of DL_FLAG_SYNC_STATE_ONLY flag [1] to device
links, all the valid dependency cycles due to "proxy" device links
(needed for correctness of sync_state() device callback) will never fail
device_link_add() due to cycles.

So, continuing to retry failing device links (by returning -EAGAIN) is
no longer useful. At worst, it prevents platforms from setting
fw_devlink=on (or better) because it prevents proper boot up. So, let's
not do that anymore.

Frank Rowand 29acfb6559 of: unittest: kmemleak in duplicate property update
kmemleak reports several memory leaks from devicetree unittest.
This is the fix for problem 5 of 5.

When overlay 'overlay_bad_add_dup_prop' is applied, the apply code
properly detects that a memory leak will occur if the overlay is removed
since the duplicate property is located in a base devicetree node and
reports via printk():

  OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail
  OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail

The overlay is removed when the apply code detects multiple changesets
modifying the same property.  This is reported via printk():

  OF: overlay: ERROR: multiple fragments add, update, and/or delete property /testcase-data-2/substation@100/motor-1/rpm_avail

As a result of this error, the overlay is removed resulting in the
expected memory leak.

Add another device node level to the overlay so that the duplicate
property is located in a node added by the overlay, thus no memory
leak will occur when the overlay is removed.

Thus users of kmemleak will not have to debug this leak in the future.
