-From: Hauke Mehrtens <hauke@hauke-m.de>
-Subject: mtd: part: add generic parsing of linux,part-probe
-
-This moves the linux,part-probe device tree parsing code from
-physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
-providing a reference to their device tree node in struct
-mtd_part_parser_data.
-
-THIS METHOD HAS BEEN DEPRECATED
-
-Linux supports "compatible" property in the "partitions" subnode now. It
-should be used to specify partitions format (and trigger proper parser
-usage) if needed.
-
