Sorry, I just updated this patch description in v2 to indicate why they are not
hard-coded, but didn't answer explicitly. As the firmware changes, a different
revision of it can have a different time before it sleeps in its configuration,
or the time it takes it to startup may be different. Thus, there's a way to
set it here w/o changing the driver.

This sort of stuff should be read out of the firmware, not DT..

Why has Google created such a non-standard TPM firmware???
