The power and force recovery buttons found on Jetson Xavier are hooked
up to two Tegra GPIOs. The power button can also function as a wake-up
source.

The AON GPIO controller is in an always-on power partition and typically
provides pins for functions that need to always work, such as the power
key for example.

The on-die RTC isn't hooked up to a backup battery, so it isn't useful
to track time across reboots, but as long as power remains enabled, it
keeps track of time accurately and can be used to wake the system from
sleep, for example.

The RTC on Tegra194 is very similar to the RTC on earlier generations.
One notable exception is that the source clock is now the 32 kHz clock
instead of a dedicated RTC clock and the RTC alarm is a wake event and
can be used to wake the system from sleep.

Wake events are a feature that allows the interrupt and GPIO controllers
to be powered off as part of system sleep. The PMC which is always on is
monitoring these wake events and can power up subsequent controllers as
necessary to process them.

Tegra194 contains a display architecture very similar to that found on
