2021-03-27docs: dt: Group DT docs into relevant sub-sectionsRob Herring
The DT docs are currently all just lumped together in the doc build. Let's organize the documents by kernel specifics, overlays and bindings. As writing-schema.rst is about bindings, let's move it to the bindings directory.

2021-03-27docs: dt: Make 'Devicetree' wording more consistentRob Herring
There's a variety of ways 'Devicetree' has been written. This is most evident in the documentation build contents where we have 'Device Tree', 'DeviceTree', etc. The DT spec has somewhat standardized on 'Devicetree', so let's use that.

2021-03-27docs: dt: writing-schema: Remove spurious indentationRob Herring
'allOf' and 'properties' have a leading space which causes them to be indented in the doc output.

2020-03-13kbuild: allow to run dt_binding_check and dtbs_check in a single commandMasahiro Yamada
Since commit 93512dad334d ("dt-bindings: Improve validation build error handling"), 'make dtbs_check' does not validate the schema fully. If you want to check everything, you need to run two commands separately. $ make ARCH=arm dt_binding_check $ make ARCH=arm dtbs_check They are exclusive each other, so you cannot do like this: $ make ARCH=arm dt_binding_check dtbs_check In this case, dt-doc-validate and dt-extract-example are skipped because CHECK_DTBS is set. Let's make it possible to run these two targets in a single command. It will be useful for schema writers.

2019-11-14dt-bindings: Improve validation build error handlingRob Herring
Schema errors can cause make to exit before useful information is printed. This leaves developers wondering what's wrong. It can be overcome passing '-k' to make, but that's not an obvious solution. There's 2 scenarios where this happens. When using DT_SCHEMA_FILES to validate with a single schema, any error in the schema results in processed-schema.yaml being empty causing a make error. The result is the specific errors in the schema are never shown because processed-schema.yaml is the first target built. Simply making processed-schema.yaml last in extra-y ensures the full schema validation with detailed error messages happen first. The 2nd problem is while schema errors are ignored for processed-schema.yaml, full validation of the schema still runs in parallel and any schema validation errors will still stop the build when running validation of dts files. The fix is to not add the schema examples to extra-y in this case. This means 'dtbs_check' is no longer a superset of 'dt_binding_check'. Update the documentation to make this clear.

2019-08-13devicetree: Expose dtbs_check and dt_binding_check some moreStephen Boyd
It wasn't obvious that this was a command to run based on 'make help', so add it to the top-level help for devicetree builds. Also, add an example to the documentation to show that db_binding_check can be run with DT_SCHEMA_FILES= to only check one schema file instead of all of them.
