Yep, good data (especially on the function of the PMIC) would be pretty nice, at least to get a rough idea of feasibility.
The PMS01 IC provides all the functionalities needed except the mosfet for chaining the chip into a string.
For the one-chip board, we still choose to use it instead of a bunch of buffers and LDOs for board simplicity.
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.
Adding the core voltages to the GH/W table would still be quite nice. That would help people get a jump on figuring out designs for these chips.
