A typical power down sequence is to have the Power-on-Reset asserted, clock shut down, and ramp down all the power supplies sequentially in the exact reverse order of the power-up sequencing. In other words, the power supply that has been ramped up first should be the last one that is ramped down.
For AM654x/AM652x, there are no specific power-down sequencing requirements, except for asserting Power-on-Reset before ramping down the rails while bypassing internal POR.
