of: Add of_machine_get_match() helper

2026-03-13T22:00:04+00:00

Currently, there are two helpers to match the root compatible value
against an of_device_id array:
  - of_machine_device_match() returns true if a match is found,
  - of_machine_get_match_data() returns the match data if a match is
    found.
However, there is no helper that returns the actual of_device_id
structure corresponding to the match, leading to code duplication in
various drivers.

Fix this by reworking of_machine_device_match() to return the actual
match structure, and renaming it to of_machine_get_match().
Retain the old of_machine_device_match() functionality using a cheap
static inline wrapper around the new of_machine_get_match() helper.

Just like looping through children and available children, add a scoped
helper for for_each_compatible_node() so error paths can drop
of_node_put() leading to simpler code.

of: Add wrappers to match root node with OF device ID tables

2025-11-27T01:38:24+00:00

Several drivers duplicate same code for getting reference to the root
node, matching it against 'struct of_device_id' table and getting out
the match data from the table entry.

There is a of_machine_compatible_match() wrapper but it takes array of
strings, which is not suitable for many drivers since they want the
driver data associated with each compatible.

Add two wrappers, similar to existing of_device_get_match_data():
1. of_machine_device_match() doing only matching against 'struct
   of_device_id' and returning bool.
2. of_machine_get_match_data() doing the matching and returning
   associated driver data for found compatible.
