From ec9c08a1cb8dc5e8e003f95f5f62de41dde235bb Mon Sep 17 00:00:00 2001

Subject: [PATCH] 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.
