As the at25 uses the NVMEM subsystem, and the property is now being
handled, adding reference for it in the device tree binding document,
which allows to specify the GPIO line to which the write-protect pin
is connected.

Hi Greg,
AT25 patches usually go through the char-misc tree. In this case
however, the change depends on the other patches in this series. Can
you ack this and I'll take it through the AT24 tree exceptionally?
Best regards,
Bartosz Golaszewski
