Subject: [PATCH] ARM: MXS: ocotp: Register a separate device
Date: Fri, 12 Jun 2015 11:55:11 +0200	[thread overview]
Message-ID: <1434102911-1063-1-git-send-email-s.hauer@pengutronix.de> (raw)

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.
