As a consequence, define the requisite node and the compatible string, which in-turn tidies up the dtb check results. Signed-off-by: Andrew Jeffery Reviewed-by: Rob Herring (Arm) --- Hello, This change was original part of an RFC series tidying up the AST2600 EVB devicetree at [1]. Many of those ended up being merged directly, so I'm splitting out what remains into separate, smaller series. Please review. Changes since RFC: - Address the warning from Rob's bot - Tidy a description line that was dropped unnecessarily - Remove RFC label Link: https://lore.kernel.org/all/20251211-dev-dt-warnings-all-v1-16-21b18b= 9ada77@codeconstruct.com.au/ [1] --- .../devicetree/bindings/mfd/aspeed,ast2x00-scu.yaml | 17 +++++++++++++= ++++ 1 file changed, 17 insertions(+) diff --git a/Documentation/devicetree/bindings/mfd/aspeed,ast2x00-scu.yaml = b/Documentation/devicetree/bindings/mfd/aspeed,ast2x00-scu.yaml index da1887d7a8fe..a87f31fce019 100644 --- a/Documentation/devicetree/bindings/mfd/aspeed,ast2x00-scu.yaml +++ b/Documentation/devicetree/bindings/mfd/aspeed,ast2x00-scu.yaml @@ -130,6 +130,23 @@ patternProperties: - description: silicon id information registers - description: unique chip id registers =20 + '^smp-memram@[0-9a-f]+$': + description: Memory region used for the AST2600's custom SMP bringup p= rotocol + type: object + additionalProperties: false + + properties: + compatible: + const: aspeed,ast2600-smpmem + + reg: + description: The SMP memory region + maxItems: 1 + + required: + - compatible + - reg + required: - compatible - reg --- base-commit: 8f0b4cce4481fb22653697cced8d0d04027cb1e8 change-id: 20260109-dev-dt-warnings-mfd-b57e0e9fdcf8 Best regards, --=20 Andrew Jeffery
