Subject: [PATCH v2 3/3] ARM: dts: dra72-evm: drop NAND support
Date: Tue, 13 Dec 2016 16:59:47 +0530	[thread overview]
Message-ID: <a2d251a432c5c8519dd31441a6427a261b16ca79.1481628266.git.nsekhar@ti.com> (raw)
In-Reply-To: <cover.1481628266.git.nsekhar@ti.com>

For the existing IOdelay configuration via U-Boot, NAND is
not supported on dra72-evm (both Rev B and Rev C).

Disable it. Commit 46cfc8945887 ("ARM: dts: dra72-evm: Remove
pinmux configurations for erratum i869") has already removed
pinmuxing for NAND making it unusable.
