a5dd239140 footprints: led: replace silk pad with circle
Replace the previous silk "pad" with an actual circle.  Many tools don't
cope well with pads on the silk layer.

7ced97dab4 sch: update part number for VBUS TVS
It was listed as a part number from Diodes, Inc.  The MPN and
Manufacturer were correct, but the schematic part number was wrong.

1fc4fb09eb pcb: increase pad size for TVS diodes
The pad size was sized exactly, which would result in assembly
errors for the TVS diodes.  Add some margin to the pad size.

e9067ac372 footprints: increase copper area for TVS diodes
We only had the bare minimum of copper, which didn't leave a lot of room
for the pick-and-place machine to err.  Increase the footprint size for
the TVS diodes.

They say that pads must be 0.23mm to ensure the laser doesn't escape the

0a7b84d1c3 hardware: replace VCCPLL regulator with RC network
Having a full regulator on VCCPLL causes the ESD network in the ICE40 to
freak out, dumping VCCPLL into GND and trying very hard to burn out the
regulator.

Replace it with a simple RC filter network, which is less clean but
results in a happier ESD network.
