+Subject: dt-bindings: mtd: brcm,trx: Add brcm,trx-magic
+
+This adds the description of an additional property which allows to
+specify a custom partition parser magic to detect a trx partition.
+Buffalo has multiple device which are using the trx format, but with
+different magic values.

-
-Buffalo uses a different TRX magic for every device, to be able to use
-this trx parser, make it possible to specify the TRX magic in device
-tree. If no TRX magic is specified in device tree, the standard value
-will be used. This value should only be specified if a vendor chooses to
-use a non standard TRX magic.

TRX is a firmware format used by Broadcom on their devices. It
may contain up to 3/4 partitions (depending on the version).
