Subject: [PATCH v3 4/5] mtd: mchp23k256: add partitioning support
Date: Tue, 23 May 2017 12:43:16 +1200 [thread overview]
Message-ID: <20170523004317.16908-5-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20170523004317.16908-1-chris.packham@alliedtelesis.co.nz>
Setting the of_node for the mtd device allows the generic mtd code to
setup the partitions. Additionally we must specify a non-zero erasesize
for the partitions to be writeable.
