I believe the nfc (also, nc) abbreviation pre-dates the NFC spec. But I
agree, it may be misleading. Even though I don't foresee any NAND
controller with NFC coming, it's probably bad for newcomers/people who
are not already deeply into the mtd details to use these confusing
letters, especially in a binding.

So, Ack.

Yeah, why would it be too long? Let's call a cat a cat. This is a
compatible for a NAND controller. So I expect the string to mention
it's a NAND controller because it's clearer. For quite some time there
has been a confusion between the NAND controller and the NAND
flash/chip, but these are two different hardware components.

For the above reason, no :)

Thanks,
