u-boot 2017.03 PMIC read error

Hello all,

 

As seen in below logs, I am not able to boot u-boot 2017,  but the PMIC with same ID and configuration works in u-boot 2016.

 

Is there any difference in the way we port for u-boot 2017.08. Did anyone try this newer version of u-boot. It looks completely new since it has dts like kernel has.
