Analyze and fix the following issue in the Linux kernel code: dt-bindings: vendor-prefixes: Add "test" vendor for KUnit and friends
Problem Details: Add the vendor prefix "test" to reserve a vendor prefix for bindings that are purely for testing device tree code. This allows test code to write bindings that can be checked by the schema validator. Reviewed-by: Rob Herring <robh@kernel.org> Reviewed-by: David Gow <davidgow@google.com> Cc: Krzysztof ...
