[PATCH v2 6/7] of: property: fw_devlink: Follow clock nexus maps

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke@xxxxxxxxxxx>

Clock consumers use of_parse_phandle_with_args_map() to resolve
specifiers through clock-map properties. fw_devlink instead parses the
clocks property as a direct phandle reference, so it records the nexus
node as the supplier rather than the mapped clock provider.

A nexus is a translation node, not the clock provider, and need not be
populated as a device. The resulting fwnode link can therefore remain
unresolved and indefinitely defer the consumer while
device_links_check_suppliers() waits for the nexus.

Use the map-aware parser for clocks so fw_devlink resolves the same
provider as the clock consumer API. Direct clock references continue to
work because the map-aware parser returns the original provider when no
clock-map property is present.

Fixes: aacc54c67869 ("clk: Add support for clock nexus dt bindings")
