Make sure the reader of the document is aware that some active
installation of the libyaml development package is required and
provide two examples.

Rob Herring 93512dad33 dt-bindings: Improve validation build error handling
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.

Rob Herring 7054c207b0 dt: writing-schema: Add a note about tools PATH setup
Users without an existing python install may not have their PATH setup
for pip installed python programs already. Add a note about having the
DT validation programs in the PATH.

Stephen Boyd 7aa8dd91da devicetree: Expose dtbs_check and dt_binding_check some more
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.
