+Subject: [PATCH 06/11] mtd: nand: drop unnecessary partition parser data
+
+All of these drivers set up a parser data struct just to communicate DT
+partition data. This field has been deprecated and is instead supported
+by telling nand_scan_ident() about the 'flash_node'.
+
+This patch:
+ * sets chip->flash_node for those drivers that didn't already (but used
+   OF partitioning)
+ * drops the parser data
+ * switches to the simpler mtd_device_register() where possible, now
+   that we've eliminated one of the auxiliary parameters
+
+Now that we've assigned chip->flash_node for these drivers, we can
+probably rely on nand_dt_init() to do more of the DT parsing for us, but
+for now, I don't want to fiddle with each of these drivers. The parsing
+is done in duplicate for now on some drivers. I don't think this should
+break things. (Famous last words.)
+

 This field is no longer used anywhere, as it is superseded by
 mtd->dev.of_node.

+Subject: [PATCH 11/11] mtd: physmap_of: assign parent for the concatenated MTD
+
+If there is more than one map region for this device, then the
+concatenated MTD will not have a parent device assigned to it -- only
+the sub-devices (which are not actually registered with the framework)
+will have their parents assigned. Let's assign the concatenated device
+correctly.
