sys/dev/acpi : amdpmc.c
Log message:
Add SMU support to amdpmc(4). The SMU is a microcontroller buried deep
in the bowels of AMD SoCs and needs to be tickled in order to reach the
lowest power states in suspend. It also provides some information on
whether we actually reached those lower states.
On most machines we will need to tell the USB4 controllers to go to sleep
to reach these states. So it is likely that we won't reach S0i3 yet on
those machines.
