AWR1843BOOST: LP87524JRNFRQ1 in AWR1843BOOST based custom Board

Tool/software:

Hi...,

We are developing a custom board based on AWR1843BOOST. The IC is AWR1843QAGABL, and the power IC we are going to keep is the PMIC(LP87524JRNFRQ1). 

We are not using any XDS microcontroller but we are keeping 60pin connector for DCA1000EVM, So LP87524JRNFRQ1's SDA and SCL pins should go to 60pin connector only right......sholud we connect it to AWR IC also.....

and also can we keep LP87524JRNFRQ1's CLKIN pin floating since we are not using any external clock to the PMIC.

Thanks
