I am trying to interface pcf8574(i2c-gpio expander) with rk3399 and AIO 3399J using the i2c4 port.I have also added basic details of pcf8574 in the 'rk3399-firefly-port.dtsi' file.But I do not know how to define and register the i2c device/driver in dts file.They have mentioned the steps for device/driver registration but I could not understand it.
