Subject: [PATCH v7 04/15] dt-bindings: nvmem: Add fsl,scu-ocotp yaml file
From: Abel Vesa <abel.vesa@....com>
In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'ocotp' child node of the SCU main node.
