Subject: [PATCH v3 03/16] dt-bindings: qcom_nandc: make nand-ecc-strength optional
Date:   Fri, 25 May 2018 17:51:31 +0530
Message-Id: <1527250904-21988-4-git-send-email-absahu@codeaurora.org>
In-Reply-To: <1527250904-21988-1-git-send-email-absahu@codeaurora.org>
References: <1527250904-21988-1-git-send-email-absahu@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

If nand-ecc-strength specified in DT, then controller will use
this ECC strength otherwise ECC strength will be calculated
according to chip requirement and available OOB size.

 Each nandcs device node may optionally contain a 'partitions' sub-node, which
 further contains sub-nodes describing the flash partition mapping. See
