TPS65916: TPS65916 and the Sitara AM5716AABCD: any U-boot requirement or Does the PMIC can be standalone during the boot sequence?

Part Number:TPS65916

During the boot-up of the AM5716, does it require any special interraction with the TPS65916? Any I2C communication to adjust voltage rail or any others features (any specific code for the boot-loader)?

We find some code which write in some register, but doesn't make sense, since it's a different PMIC or eval board.

Thanks
