From b744cc33d5038753dfcb43e6cd186208d0197a62 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Fri, 12 Jun 2015 08:49:01 +0200 Subject: [PATCH] ARM: MXS: ocotp: Register a separate device With device tree the device name starts with a number, so the device parameters are not accessible on the shell. Register a separate device for the ocotp to make the permanent_write_enable variable accessible again.
