NDAs vary quite considerably; the last NDA I was under for a chip was simply because the "documentation" consisted of the VHDL source for the various bits of chip, an e-mail address for the hardware team responsible, and a phone number to get hold of the team leader.

I was permitted to use this information to document the chip on a "pins" basis; basically, I couldn't say how the chip did something, but I could say things like "the value in the register at offset 0x2c controls the width of the output pulse on pin 23. It's a count of the number of pulses of XTAL1 (wired between pins 5 and 6) for which pin 23 stays high". An NDA of this form would let Greg release both a driver and register-level documentation for the chip he's working on.
