From 6d04828b45202312c93892b4be834809c795d4d2 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sun, 2 Nov 2025 14:08:12 -0600 Subject: [PATCH] dm: Remove pre-schema tag support Support for using "u-boot,dm-..." rather than "bootph-..." has been deprecated since February 2023. Any platforms using this have had a console message saying to migrate by 2023.07. Go and remove all support here now, for the v2026.01 release. The results of this change that aren't clear from the above are that we still have a checkpatch.pl error message, and document in doc/develop/spl.rst that they have been migrated since 2023. We also change the key2dtsi.py tool to use the correct bootph phase rather than the legacy phase.
