Linux uses it. libeopencm uses it. spidev uses it. But hardware doesn't. The API is fine when you bitbang everything, but not when there's a controller that takes over some of the work, like programming the address.
On such a controller, you have to pick apart struct i2c_seg* to figure out which elements are addresses and which are data, and split things into different registers. I really don't see how it's useful to keep the data structures as low level as possible and then require drivers for more capable devices to uplift them to a higher abstraction level. Patrick
