In order to notify the system about the status this feature, a GPIO is
typically used.
The map between a GPIO and the feature is done via ACPI, the same way as
the reset_gpio works.
Would you mind pointing me to the patches that implement this on the kernel side?
For the privacy_pin, this is the series:

for the reset_gpio
