|     nvmem: Create a header for internal sharing
|
|     Before adding all the NVMEM layout bus infrastructure to the core, let's
|     move the main nvmem_device structure in an internal header, only
|     available to the core. This way all the additional code can be added in
|     a dedicated file in order to keep the current core file tidy.

which is required for the upcoming nvmem-layout support.
