title: ARMv8-M Memory Protection Unit
dts: bindings: Preserve newlines in descriptions With https://github.com/zephyrproject-rtos/zephyr/pull/20185, multi-line descriptions will be formatted nicely, but using '>' breaks it, because it removes internal newlines (including between paragraphs). See https://yaml-multiline.info/. Replace 'description: >' with 'description: |' to encourage '|'. That'll prevent '>' from getting copied around and messing up long descriptions. This will lead to some extra newlines in the output, but it's fine. Line-wrapping messes up any manual formatting. The replacement was done with $ git ls-files 'dts/bindings/*.yaml' | \ xargs sed -i 's/description:\s*>/description: |/' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

This binding describes the ARMv8-M Memory Protection Unit (MPU).
scripts: dts: Simplify and improve 'compatible' matching Instead of properties: compatible: constraint: "foo" , just have compatible: "foo" at the top level of the binding. For backwards compatibility, the old 'properties: compatible: ...' form is still accepted for now, and is treated the same as a single-element 'compatible:'. The old syntax was inspired by dt-schema (though it isn't dt-schema-compatible), which is in turn a thin wrapper around json-schema (the idea is to transform .dts files into YAML and then verify them). Maybe the idea was to gradually switch the syntax over to dt-schema and then be able to use unmodified dt-schema bindings, but dt-schema is really a different kind of tool (a completely standalone linter), and works very differently from our stuff (see schemas/dt-core.yaml in the dt-schema repo to get an idea of just how differently). Better to keep it simple. This commit also piggybacks some clarifications to the binding template re. '#cells:'. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

dts/bindings: Convert bindings to new include syntax Convert from: inherits: !include spi-device.yaml to: include: spi-device.yaml Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

include: base.yaml
dts/bindings: Move common properties into a base.yaml Move common properties like 'compatible', 'reg', 'reg-names', 'interrupts', 'interrupt-names', and 'label' into one common base.yaml that all the other yaml's can inherit from. This removes both duplication and inconsistent definition. The device specific yamls just need to say if a property is 'required' or not. NOTE: due to some generation conflicts we did not covert 'soc-nv-flash.yaml' to use base.yaml. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

Print a clear error when 'category:' is used: edtlib.EDTError: please put 'required: true' instead of 'category: required' in 'properties: foo: ...' in test-bindings/sub-node-parent.yaml - 'category' has been removed The old scripts in scripts/dts/ ignore this setting, and only print a warning if 'category: required' in an inherited binding is changed to 'category: optional'. Remove that code, since the new scripts already have the same check.
