Subject: [PATCH v2 12/22] mtd: nand: omap: Update DT binding documentation
Date: Fri, 7 Aug 2015 12:12:22 +0300 [thread overview]
Message-ID: <1438938752-31010-13-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1438938752-31010-1-git-send-email-rogerq@ti.com>
Add compatible id and interrupts. The NAND interrupts are
provided by the GPMC controller node.
