How come this driver isn't doing any manipulation with the VDDIO
voltage -- or did I miss that? I seem to remember that the VDDIO
had to be lowered to 2.8V before the fuses could be programmed
and restored to 3.3V afterward. See for example recent mainline
u-boot, drivers/misc/mxs_ocotp.c .
Best regards,
