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

[Abhishek Sahu]

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.

As mentioned in my other review, no need to specify nand-ecc-step-size
if you don't have a choice. You can remove the property and say that
nand-ecc-strength encodes the ECC strength for 512 bytes chunks.

Same comment as before: don't start the commit log with "now,".

  Thanks Miquel.
  I will change the commit message.
