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

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,
