Here is how to find the answer. In the drivers "data" directory, there is a ".mdd" file which indicates for which core it is intended to be used: For the iic_v3_1 driver, the iic.mdd file indicates: OPTION supported_peripherals = (axi_iic); For the psiic_v3_0 driver, the psiic.mdd file indicates: OPTION supported_peripherals = (ps7_iic psu_i2c); In summary, the iic driver is intended to be used with the AXI_IIC core, the IIC controller implemented in the programmable logic. Whereas the psiic driver is intended to be used with the Zynq-7000 or Zynq-UltraScale's built-in IIC controller's. Hope this helps ! Mario.
