The iic(4) manual page lists quite a few devices, although it is not
entirely comprehensive.[*]

But if you mean whether it is possible to scan the I2C devices possibly
available on the machine, I believe no such functionality exists, at least
by default. However, if you take a peek at iic(9) and 'src/sys/dev/i2c/i2c.c',
there is a #ifdef I2C_SCAN. I haven't tried it, so I do not know how well it
works.
