As I understand it, I2C can be used for high-speed communication, so as fast as you can realistically pull that clock line is how fast you can go. Hense the clock line. I would look at it holistically. The BBB can probably really reef on that clock line (1 Ghz processor...kernel aside) so I'd look at the peripheral's core clock speed and figure how fast you can realistically do it. Just an opinion.
