   4 Subject: [PATCH] nvmem: core: move struct nvmem_cell_info to nvmem-provider.h
   5
   6 struct nvmem_cell_info is used to describe a cell. Thus this should
   7 really be in the nvmem-provider's header. There are two (unused) nvmem
   8 access methods which use the nvmem_cell_info to describe the cell to be
   9 accesses. One can argue, that they will create a cell before accessing,
  10 thus they are both a provider and a consumer.
  11
  12 struct nvmem_cell_info will get used more and more by nvmem-providers,
  13 don't force them to also include the consumer header, although they are
  14 not.
