IT61620 is a variant of IT6162. The main differences are listed below - IT61620 supports only a single MIPI DSI input port, while IT6162 supports dual MIPI DSI ports. - IT61620 does not include the internal MCU present in IT6162. Because of these architectural differences, IT61620 uses a separate compatible string even though the external interfaces and bindings are largely similar.
