This chip is present on at least these Apple T2 Macs:
* hawaii: MacBook Air 13" (Late 2018)
* hawaii: MacBook Air 13" (True Tone, 2019)
Users report seeing PCI revision ID 12 for this chip, which Arend
reports should be revision C2, but Apple has the firmware tagged as
revision C1. Assume the right cutoff point for firmware versions is
revision ID 11 then, and leave older revisions using the non-versioned
firmware filename (Apple only uses C1 firmware builds).
