The diff D43811 has been split into two parts. This part consists in the splitting of the original vf_i2c driver between the FDT-specific code and the I2C controller code, as well as the introduction of ACPI-specific code. The original I2C controller logic has been kept. The FDT driver from this code should work whenever the original FDT driver worked. The second part is D44021 and it changes the I2C controller logic so it is more consistent with the reference manual for the controller.
