cks. The root-node schema requires a 'model' string; without it, `dtbs_check` warns: "'model' is a required property". Adding the property resolves this concrete warning. - Minimal, contained change: One line added to a single board DTS. See arch/mips/boot/dts/lantiq/danube_easy50712.dts:7 where `model = "Intel EASY50712";` is introduced immediately under the root node. - No functional or binding changes: The property is descriptive and does not alter any hardware description, node layout, or compatible strings. Drivers do not consume 'model' for behavior, so risk of regression is negligible. - Improves user visibility without side effects: Kernel code and userspace commonly read the model string for identification (e.g., “Machine model” logs and sysfs/proc exposure). While many subsystems read ‘model’, the Lantiq MIPS platform’s `get_system_type()` does not depend on DT ‘model’ (arch/mips/lantiq/prom.c: get_system_type()), further reducing any risk of changing existing behavior. Other generic paths that read ‘model’ benefit from correctness (examples of readers found via semantic search include drivers/soc/* and others). - Stable-friendly profile: - Bugfix: resolves a schema compliance warning and ensures a complete, standards-conformant DT. - Trivial and localized: a single-line addition in one DTS file. - No architectural changes or critical subsystem churn. - Very low regression risk; likely improves diagnostics and tooling. Given it corrects a required DT property with a minimal, safe change confined to one board DTS, this is a good candidate for stable backport. arch/mips/boot/dts/lantiq/danube_easy50712.dts | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/mips/boot/dts/lantiq/danube_easy50712.dts b/arch/mips/boot/dts/lantiq/danube_easy50712.dts index c4d7aa5753b04..ab70028dbefcf 100644 --- a/arch/mips/boot/dts/lantiq/danube_easy50712.dts +++ b/arch/mips/boot/dts/lantiq/danube_easy50712.dts @@ -4,6 +4,8 @@ /include/ "danube.dtsi" / { + model = "Intel EASY50712"; + chosen { bootargs = "console=ttyLTQ0,115200 init=/etc/preinit"; }; -- 2.51.0[PATCH AUTOSEL 6.17-6.1] mips: lantiq: danube: add model to EASY50712 dtsSasha Levin undefinedpatches@lists.linux.dev, stable@vger.kernel.org undefined undefined undefined undefined undefined undefined undefined|
