Hi Prathosh

Your email quoting is very odd, i nearly missed this reply.

Does the device itself have an ID register? If you know you have
something in the range ZL30731 to ZL30735, you can ask the hardware
what it is, and the driver then does not need any additional
information from DT, it can hard code it all based on the ID in the
register?
