[PATCH 1/2] dt-bindings: nvmem: imx-ocotp: update the binding to reflect data cells

From: Dong Aisheng
Date: Thu Jan 25 2018 - 04:25:34 EST


imx-ocotp is implemented based on nvmem which can have data cells
as child node. Update the binding doc to reflect it to be more easily
understood by users.
