-Subject: [PATCH] nvmem: core: add per-cell post processing
-
-Instead of relying on the name the consumer is using for the cell, like
-it is done for the nvmem .cell_post_process configuration parameter,
-provide a per-cell post processing hook. This can then be populated by
-the NVMEM provider (or the NVMEM layout) when adding the cell.
