+
+We are going to begin using the mtd->dev.of_node field for MTD device
+nodes, so let's add helpers for it. Also, we'll be making some
+conversions on spi_nor (and nand_chip eventually) too, so get that ready
+with their own helpers.

+Subject: [PATCH] mtd: ofpart: grab device tree node directly from master
+ device node
+
+It seems more logical to use a device node directly associated with the
+MTD master device (i.e., mtd->dev.of_node field) rather than requiring
+auxiliary partition parser information to be passed in by the driver in
+a separate struct.
+
+This patch supports the mtd->dev.of_node field and deprecates the parser
+data 'of_node' field
+
+Driver conversions may now follow.
+
+Additional side benefit to assigning mtd->dev.of_node rather than using
+parser data: the driver core will automatically create a device -> node
+symlink for us.
