Subject: [PATCH 2/2][RESEND] arm64: dts: Add big-endian in nor node for ls104xa
Date: Tue, 28 Aug 2018 12:29:36 +0530	[thread overview]
Message-ID: <20180828065936.8040-3-prabhakar.kushwaha@nxp.com> (raw)
In-Reply-To: <20180828065936.8040-1-prabhakar.kushwaha@nxp.com>

NOR and IFC controller connectivity is big-endian.
So add big-endian field in nor device tree node allowing
IFC controller to read/write data from/to the flash correctly.
