[PATCH 0/2] dt-bindings: DTB based validation

[Rob Herring <robh@kernel.org>]

This series switches the kernel's DT schema validation from YAML encoded
DT files to using DTB files directly. See patch 2 for the full reasoning
of why. The diffstat also shows this is a nice simplification (at least 
from the kernel side). Patch 1 is further reworking of how 
DT_SCHEMA_FILES works and builds on [1].

Overall, the build time is about the same (still slow) though we do save 
a dtc call for dtbs_check. Extracting the type information is not cached 
in any way, so there's some opportunity for a slight optimization there. 

Switching to DTB validation found various issues in the bindings and 
examples. Patches for those issues have already been posted and applied 
over the last month or so.
