In reply to: Boris Brezillon: "[PATCH v3 3/7] mtd: nand: add a nand.h file to expose basic NAND stuff"
Next in thread: Boris Brezillon: "[PATCH v3 5/7] mtd: nand: raw: create struct rawnand_device"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Some raw NAND function names conflict with names defined in nand.h.
Prefix all those functions with nandc (for nand chip) instead of nand so
we can include nand.h from rawnand.h
