-Subject: [PATCH] nvmem: sfp: Use regmap
-
-This converts the SFP driver to use regmap. This will allow easily
-supporting devices with different endians. We disallow byte-level
-access, as regmap_bulk_read doesn't support it (and it's unclear what
-the correct result would be when we have an endianness difference).
