This is what most i2c master drivers would need to do anyhow. I have
never heard of hardware support for that. Do you know an IP core which
does that? And how are timeouts defined/handled?

Currently, this is not supported in Linux I2C. It probably could be
using another I2C_M_* flag, but a number of details need to be designed
and implemented first. Would you be interested?
