Subject: [PATCH v2 03/14] dt-bindings: qcom_nandc: make nand-ecc-strength optional

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.

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