[v3] of/treewide: Simplify with for_each_compatible_node_scoped()

[PATCH v3 00/12] of/treewide: Simplify with for_each_compatible_node_scoped()

Posted by Krzysztof Kozlowski 1 month ago

Dependencies/merging
====================
1. First patch is a prerequisite for entire set, so either everything
   goes via same tree, the further patches wait a cycle or stable tag is
   shared from DT tree.

2. The last media patch depends on my earlier cleanup.

Changes in v3:
- New patch: cdx: Use mutex guard to simplify error handling
- Collect tags
- Link to v2: https://patch.msgid.link/20260106-of-for-each-compatible-scoped-v2-0-05eb948d91f2@oss.qualcomm.com

Changes in v2:
- Update also scripts/dtc/dt-extract-compatibles (Rob)
- Collect tags
- Link to v1: https://patch.msgid.link/20260105-of-for-each-compatible-scoped-v1-0-24e99c177164@oss.qualcomm.com

Description
===========
Simplify for_each_compatible_node() users with a new helper -
for_each_compatible_node_scoped().

Best regards,
Krzysztof

I applied all but the last patch which did not apply for me. Send it 
next cycle.
