-Subject: [PATCH] mtd: nand: Add DT NAND partition parser
-
-Add a of_nandpart_parse function to help parsing NAND partitions from DT.
-This function should be called from NAND controller drivers just after the
-nand_scan_tail in place of mtd_device_parse_register.
-The caller can specify a parser function to retrieve HW specific
-informations from the DT.
