All i.MX6 SoCs have an OCOTP Controller with 4kbit fuses. The i.MX6SL is
an exception and has only 2kbit fuses.
In the TRM for the i.MX6DQ (IMX6QDRM - Rev 2, 06/2014) the fuses size is
described in chapter 46.1.1 with:
"32-bit word restricted program and read to 4Kbits of eFuse OTP(512x8)."
In the TRM for the i.MX6SL (IMX6SLRM - Rev 2, 06/2015) the fuses size is
described in chapter 34.1.1 with:
"32-bit word restricted program and read to 2 kbit of eFuse OTP(128x8)."
Since the Freescale Linux kernel OCOTP driver works with a fuses size of
2 kbit for the i.MX6SL, it looks like the TRM is wrong and the formula
to calculate the correct fuses size has to be 256x8.

Bai Ping (Cc'ed here) from NXP is sending similar patches [1]. DTS
change looks good to me, but I will not apply it until the driver and
bindings get accepted.

As Shawn said, there is already a similar patch in the mailing list
http://www.spinics.net/lists/arm-kernel/msg543203.html
http://www.spinics.net/lists/arm-kernel/msg543204.html
I will pick that patch + I will queue up fix from you "[PATCH 3/3]

As Shawn said, there is already a similar patch in the mailing list
http://www.spinics.net/lists/arm-kernel/msg543203.html
http://www.spinics.net/lists/arm-kernel/msg543204.html
I will pick that patch + I will queue up fix from you "[PATCH 3/3]
nvmem: imx-ocotp: Fix wrong register size"
thanks,
