 - nand-ecc-mode : String, operation mode of the NAND ecc mode.
   Supported values are: "none", "soft", "hw", "hw_syndrome", "hw_oob_first",
   "soft_bch".
+- nand-ecc-level : Two cells property defining the ECC level requirements.
+  The first cell represent the strength and the second cell the ECC block size.
+  E.g. : nand-ecc-level = <4 512>; /* 4 bits / 512 bytes */
 - nand-bus-width : 8 or 16 bus width if not present 8
 - nand-on-flash-bbt: boolean to enable on flash bbt option if not present false
