Subject: [PATCH v2 03/14] dt-bindings: qcom_nandc: make nand-ecc-strength optional
Date: Thu,  3 May 2018 17:50:30 +0530	[thread overview]
Message-ID: <1525350041-22995-4-git-send-email-absahu@codeaurora.org> (raw)
In-Reply-To: <1525350041-22995-1-git-send-email-absahu@codeaurora.org>

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