of: Fix of_find_node_opts_by_path() handling of alias+path+options

commit b9e58c934c56aa35b0fb436d9afd86ef326bae0e upstream.

of_find_node_opts_by_path() fails to find OF device node when its
@path parameter have pattern below:

"alias-name/node-name-1/.../node-name-N:options".

The reason is that alias name length calculated by the API is wrong, as
explained by example below:

"testcase-alias/phandle-tests/consumer-a:testaliasoption".
^ ^ ^
0 14 39

The right length of alias 'testcase-alias' is 14, but the result worked
out by the API is 39 which is obvious wrong.

Fix by using index of either '/' or ':' as the length who comes earlier.

of: Correct child specifier used as input of the 2nd nexus node

commit e4c00c9b1f70cd11792ff5b825899a6ee0234a62 upstream.

API of_parse_phandle_with_args_map() will use wrong input for nexus node
Nexus_2 as shown below:

Node_1 Nexus_1 Nexus_2
&Nexus_1,arg_1 -> arg_1,&Nexus_2,arg_2' -> &Nexus_2,arg_2 -> arg_2,...
map-pass-thru=<...>

Nexus_1's output arg_2 should be used as input of Nexus_2, but the API
wrongly uses arg_2' instead which != arg_2 due to Nexus_1's map-pass-thru.

Fix by always making @match_array point to @initial_match_array into
which to store nexus output.

of: Fix error path in of_parse_phandle_with_args_map()

commit d7dfa7fde63dde4d2ec0083133efe2c6686c03ff upstream.

The current code uses some 'goto put;' to cancel the parsing operation
and can lead to a return code value of 0 even on error cases.

Indeed, some goto calls are done from a loop without setting the ret
value explicitly before the goto call and so the ret value can be set to
0 due to operation done in previous loop iteration. For instance match
can be set to 0 in the previous loop iteration (leading to a new
iteration) but ret can also be set to 0 it the of_property_read_u32()
call succeed. In that case if no match are found or if an error is
detected the new iteration, the return value can be wrongly 0.

Avoid those cases setting the ret value explicitly before the goto
calls.

of: Fix double free in of_parse_phandle_with_args_map

[ Upstream commit 4dde83569832f9377362e50f7748463340c5db6b ]

In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.

Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".

Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

Pull devicetree updates from Rob Herring:
"DT core:

- Add support for generating DT nodes for PCI devices. This is the
groundwork for applying overlays to PCI devices containing
non-discoverable downstream devices.

- DT unittest additions to check reverted changesets, to test for
refcount issues, and to test unresolved symbols. Also, various
clean-ups of the unittest along the way.

- Refactor node and property manipulation functions to better share
code with old API and changeset API

- Refactor changeset print functions to a common implementation

- Move some platform_device specific functions into of_platform.c

Bindings:

- Treewide fixing of typos

- Treewide clean-up of SPDX tags to use 'OR' consistently

- Last chunk of dropping unnecessary quotes. With that, the check for
unnecessary quotes is enabled in yamllint.

- Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
bindings to DT schema format

- Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450
Inline Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt
controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings

- Fixes for Rockchip DWC PCI binding

- Ensure all properties are evaluated on USB connector schema

- Fix dt-check-compatible script to find of_device_id instances with
compiler annotations"

The changeset code checks for a property in the deadprops list when
adding/updating a property, but of_add_property() and
of_update_property() do not. As the users of these functions are pretty
simple, they have not hit this scenario or else the property lists
would get corrupted.

With this there are 3 cases of removing a property from either deadprops
or properties lists, so add a helper to find and remove a matching
property.

Merge tag 'devicetree-for-6.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull more devicetree updates from Rob Herring:

- First part of DT header detangling dropping cpu.h from of_device.h
and replacing some includes with forward declarations. A handful of
drivers needed some adjustment to their includes as a result.

- Refactor of_device.h to be used by bus drivers rather than various
device drivers. This moves non-bus related functions out of
of_device.h. The end goal is for of_platform.h and of_device.h to
stop including each other.

- Refactor open coded parsing of "ranges" in some bus drivers to use DT
address parsing functions

- Add some new address parsing functions of_property_read_reg(),
of_range_count(), and of_range_to_resource() in preparation to
convert more open coded parsing of DT addresses to use them.

- Treewide clean-ups to use of_property_read_bool() and
of_property_present() as appropriate. The ones here are the ones that
didn't get picked up elsewhere.
