Subject: [PATCH] Documentation: binding: Update endianness usage
Date: Wed, 29 Nov 2017 16:57:35 +0530 [thread overview]
Message-ID: <1511954855-8593-1-git-send-email-prabhakar.kushwaha@nxp.com> (raw)
IFC controller version < 2.0 support IFC register access as
big endian. These controller version also require IFC NOR signals to
be connected in reverse order with NOR flash.
IFC >= 2.0 is other way around.
So updating IFC binding to take care of both using endianness field.
