Subject: [PATCH v2 03/11] mtd: {nand,spi-nor}: assign MTD of_node
Date: Fri, 30 Oct 2015 20:33:22 -0700	[thread overview]
Message-ID: <1446262410-45754-4-git-send-email-computersforpeace@gmail.com> (raw)
In-Reply-To: <1446262410-45754-1-git-send-email-computersforpeace@gmail.com>

We should pass along our flash DT node to the MTD layer, so it can set
up ofpart for us.
