Given that ERROR_RECOVERY calls into PORT_RESET for Hi-Zing the CC pins, setting CC pins to default state during PORT_RESET breaks error recovery.
Between -rc2 and -rc3 I started seeing boot issues in mainline on rk3399-roc-pc running arm64 defconfig, a bisection identified this patch as having broken things. The issues manifest as a hang while loading modules from the initd, you can see a full boot log at:
https://lava.sirena.org.uk/scheduler/job/558789
which shows a bunch of video drivers loading at the end of the log but I suspect that's not related the actual failure. A successful boot can be seen here:
https://lava.sirena.org.uk/scheduler/job/559222
I do note that the board is powered by USB PD, I've got it connected to a PD power supply which seems potentially relevant to the commit. The board had been working for a long time, at least as far as boot to initrd goes.
