[PATCH v3 05/16] mtd: rawnand: qcom: remove dt property nand-ecc-step-size

From: Abhishek Sahu
Date: Fri May 25 2018 - 08:22:41 EST


QCOM NAND controller supports only one step size (512) so
nand-ecc-step-size DT property is redundant. This property
can be removed and ecc step size can be assigned with 512 value.
