TQ-Systems incorporates an ocores I2C bus master into there IO controller for x86 systems. The registers are Intel IO mapped, and the interrupt line is not tied to the CPU, so needs to be polled. The bus can also be clocked at higher speed than the i2c default, so the requested speed needs to be passed in the platform data. There is an MFD driver which will be submitted separately, and it has a build dependency on the platform_data change. So it would be good if this could be placed into a stable branch which can be merged into the MFD tree. Or some alternative solution proposed.
