Add support for YAML encoded output YAML encoded DT is useful for validation of DTs using binding schemas. The YAML encoding is an intermediate format used for validation and is therefore subject to change as needed. The YAML output is dependent on DTS input with type information preserved. Signed-off-by: Grant Likely <grant.likely@arm.com> [robh: make YAML support optional, build fixes, Travis CI test, preserve type information in paths and phandles] Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

treesource: Maintain phandle label/path on output The dts output will just output phandle integer values, but often the necessary markers are present with path or label references. Improve the output and maintain phandle label or path references when present in dts output.

dtc: Correct invalid dts output with mixed phandles and integers The handling of "type preservation" dts output is based on the idea of "phandles with arguments" in properties, which isn't really a thing, other than a fairly common convention about how bindings are written. There's nothing preventing a binding which freely mixes phandles and other integers in an array of cells. Currently write_propval() handles this incorrectly: specifically the case of a phandle which follows a regular integer in a 32-bit cell array, but without a new '< >' delimited causing an extra TYPE_UINT32 marker to be inserted. In this case it omits the necessary space between the integer and the phandle reference, leading to output which can't be sent back into dtc and parsed. Correct this, and update tests to match. I think this is more or less correct for now, but really write_propval() is a big mess :(. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
