Subject: [PATCH 3/7] mtd: nand: davinci: check required ti,davinci-chipselect property
Date: Wed, 20 Nov 2013 17:22:21 +0200 [thread overview]
Message-ID: <1384960945-14528-4-git-send-email-ivan.khoronzhuk@ti.com> (raw)
In-Reply-To: <1384960945-14528-1-git-send-email-ivan.khoronzhuk@ti.com>
The property "ti,davinci-chipselect" is required. So we have to check
if it is set.
