Subject: [PATCH 1/4][v4][RESEND] dt-bindings: mtd-physmap: Add endianness supports
Date: Thu, 22 Feb 2018 15:45:06 +0530 [thread overview]
Message-ID: <20180222101511.29631-2-prabhakar.kushwaha@nxp.com> (raw)
In-Reply-To: <20180222101511.29631-1-prabhakar.kushwaha@nxp.com>
Connection between flash and controller is not necessary to be always
of same type. It may varies from platform to platform.
Adding endianness (optional) property to provide connection type
information.
Signed-off-by: Prabhakar Kushwaha <prabhakar.kushwaha@nxp.com>

Changes for v2: updated subject
Changes for v3: fixed typo for "big-endian"
Changes for v4: Moved binding definition in mtd-physmap.txt
as discussed at https://patchwork.ozlabs.org/patch/842543/
Resending as all patches of patchset never reaches to patchwork.
