From 470d96c850b56cd7d1cbc3e219150a92c20d310c Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Thu, 7 Jul 2022 15:50:11 +0300 Subject: [PATCH] dt-bindings: nvmem: Add fsl,scu-ocotp yaml file 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.
