I came up with MTD just because a grep for OTP showed most hits in there.
I have to admit that I didn't check whether those are actually for
the same kind of device or for something else that goes by the same
name. Having it in MTD doesn't sound too obscure though.

There are a few other references to efuse or otp in the kernel, which means
that at some point we probably want to have a common subsystem and user
interface for this, either in MTD or standalone.

Between drivers/misc/fsl_ocotp.c, drivers/soc/tegra/fuse and
drivers/mfd/ab3100-otp.c, is there any commonality that we could
base an abstract API on?

i don't have a answer to this question, but how about changing fsl_ocotp driver
to driver/soc/mxs/fuse with a similiar binary interface like the tegra ones.

Does it make sense to you?

While you are here, maybe you can check if your API and driver will also
be useful to support i.MX6 OCOTP?

I understand that I might be asking too much, and that perhaps i.MX23/28
eFuses are completely different from other another i.MX.
