# This package is for canarying new Parade PS8751 TCPC firmware versions
# on a subset of USB ports on a device, ahead of updating the revision of
# the main parade-ps8751a3-firmware package on the device.
#
# This uses the same set of firmware binary blob tarballs as the main
# package.  This exists separately so that two revisions can be installed
# concurrently.
