Switch the DT validation to use DTB files directly instead of a DTS to YAML conversion. The original motivation for supporting validation on DTB files was to enable running validation on a running system (e.g. 'dt-validate /sys/firmware/fdt') or other cases where the original source DTS is not available. The YAML format was not without issues. Using DTBs with the schema type information solves some of those problems. The YAML format relies on the DTS source level information including bracketing of properties, size directives, and phandle tags all of which are lost in a DTB file. While standardizing the bracketing is a good thing, it does cause a lot of extra warnings and churn to fix them. Another issue has been signed types are not validated correctly as sign information is not propagated to YAML. Using the schema type information allows for proper handling of signed types. YAML also can't represent the full range of 64-bit integers as numbers are stored as floats by most/all parsers. The DTB validation works by decoding property values using the type information in the schemas themselves. The main corner case this does not work for is matrix types where neither dimension is fixed. For now, checking the dimensions in these cases are skipped. Signed-off-by:

In preparation for supporting validation of DTB files, the full processed schema will always be needed in order to extract type information from it. Therefore, the processed schema containing only what DT_SCHEMA_FILES specifies won't work. Instead, dt-validate has gained an option, -l or --limit, to specify which schema(s) to use for validation. As the command line option is new, we the minimum dtschema version must be updated. Cc: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by:

Loosen this requirement and let DT_SCHEMA_FILES be a partial match.

Another pass at removing unnecessary use of 'allOf' with a '$ref'. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords.

If unittest detects a problem it will print a warning or error message to the console. Unittest also triggers warning and error messages from other kernel code as a result of intentionally bad unittest data. This has led to confusion as to whether the triggered messages are an expected result of a test or whether there is a real problem that is independent of unittest. EXPECT messages were added to unittest to report each triggered message that is expected, resulting in verbose console output. scripts/dtc/of_unittest is a new program that processes the EXPECT messages to determine whether the triggered messages occurred and also removes the excess verbosity of the EXPECT messages. More information is available from 'scripts/dtc/of_unittest_expect --help'. Signed-off-by:
