Subject: [PATCH v2 1/6] arm: dts: omap3-igep: Update OneNAND node
Date: Wed, 8 Nov 2017 08:42:49 +0100	[thread overview]
Message-ID: <20171108074249.og32u5axaeuqojku@lenoch> (raw)
In-Reply-To: <20171108074024.vwcfnqizvd7jajnh@lenoch>

Update node timings to be compatible with actual chip used
(gpmc_cs_show_timings utilized to dump values)
Also specify correct compatible property for upcoming MTD driver
DTfication.
