Subject: [PATCH][v2] dt-bindings: ifc: Update endianness usage
Date: Thu, 30 Nov 2017 09:12:22 +0530 [thread overview]
Message-ID: <1512013344-4042-1-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.
