My understanding from the datasheet is that anything except the default no-PLL config needs an external circuit to config the PLL through housekeeping SPI interface

did you find out about the clocking stuff?

I'm thinking of providing a separate clock on one of the gpio pins for the designs inside the user area

no, might be worth asking again. I only saw `user_clock2` on a "separate divider" as an alternate, but did not spot anything about driving clocks from the GPIO

the only thing I'm reasonably sure of is `wb_clk_i` = core clock = drivable directly from the dedicated clock input by default

I also have a video project, so I'm thinking the safest option is have another clock pin
