Now that ARM64 uses phys_initrd_start/phys_initrd_size, we can get rid
of its custom __early_init_dt_declare_initrd() which causes a fair
amount of objects rebuild when changing CONFIG_BLK_DEV_INITRD. In order
to make sure ARM64 does not produce a BUG() when VM debugging is turned
on though, we must avoid early calls to __va() which is what
__early_init_dt_declare_initrd() does and wrap this around to avoid

Add DT binding documentation for Sierra PHY. The PHY supports
a number of different protocols, including PCIe and USB.
The PHY lanes may be configured as single or multi-lane links.
Each link is treated as a separate sub-node. For example, if
there are 4 lanes in total the first 2 might be configured as
a multi-lane PCIe link while the other two are single lane
USB links, and in this case there would be 3 sub-nodes.
There are two resets for the PHY block (one for APB register
access, one for the PHY link) and separate resets for each
link. For multi-lane links, the reset corresponds to the
reset line on the master lane, the resets on other lanes
have no effect.

Callers of of_irq_parse_one() blindly use the pointer args.np
without checking whether of_irq_parse_one() had an error and
thus did not set the value of args.np. Initialize args to
zero so that using the format "%pOF" to show the value of
args.np will show "(null)" when of_irq_parse_one() has an
error. This prevents the dereference of a random value.
Make the same fix for callers of of_parse_phandle_with_args()
and of_parse_phandle_with_args_map().

Add test case of two fragments updating the same property. After
adding the test case, the system hangs at end of boot, after
after slub stack dumps from kfree() in crypto modprobe code.
Multiple overlay fragments adding, modifying, or deleting the same
property is not supported. Add check to detect the attempt and fail
the overlay apply.
Before this patch, the first fragment error would terminate
processing. Allow fragment checking to proceed and report all
of the fragment errors before terminating the overlay apply. This
is not a hot path, thus not a performance issue (the error is not
transient and requires fixing the overlay before attempting to
apply it again).
After applying this patch, the devicetree unittest messages will

If overlay properties #address-cells or #size-cells are already in

overlay must match the values in the live tree.
If the properties are already in the live tree then there is no
need to create a changeset entry to add them since they must

changeset and eliminates a possible memory leak.

The changeset entry 'update property' was used for new properties in
an overlay instead of 'add property'.
The decision of whether to use 'update property' was based on whether
the property already exists in the subtree where the node is being
spliced into. At the top level of creating a changeset describing the
overlay, the target node is in the live devicetree, so checking whether
the property exists in the target node returns the correct result.
As soon as the changeset creation algorithm recurses into a new node,
the target is no longer in the live devicetree, but is instead in the
detached overlay tree, thus all properties are incorrectly found to
already exist in the target.
This fix will expose another devicetree bug that will be fixed
in the following patch in the series.

unittest will change, and the unittest results will change from:
