So, all the level shifting IO lines and clocking and such? Handy. I'll have to take a closer look at a Prisma board to see exactly what the FET would be doing (I have ideas). I am looking forward to the release of documentation.
Yes. The LDO output for IO and PLL are included as well.
The FETs help balance the voltage. For BE300 we may not include them, but we need experiment to see if it's true.
