Subject[PATCH 2/8] dt-bindings: nvmem: add transformation bindings
Date
Just add a simple list of the supported devices which need a nvmem
transformations.

Also, since the compatible string is prepended to the actual nvmem
compatible string, we need to match using "contains" instead of an exact
match.
