Other Parts Discussed in Thread: TPS65910, AM3359

I am planning on using the AM3359 with the TPS65910 PMU, what is the proper sequence from initial startup of the processor at 600MHz  and the default voltage to boost into turbo mode.  Please advise if there is document or app note that explains the steps and the sequence they must be in.  Thank you.

    Am335x based Beaglebone uses TPD65217 as PMIC. It is configured to run at 720MHZ.

    For reference, you can look at how this is done in u-boot at below link. check for the function spl_board_init()
