src/sys/dev/acpi: acpi_power.c
Log Message:
Error out if we try to set power to a higher-power state than the parent's
state. This follows the "bus power state" -logic noted in the spec:
bus: D1
device A : D1 -> D0 -> error
device B : D1 -> D2 -> success
-> bus must remain in D1 due device A
Following this scheme, it is easy to derive the "bus power state" now that
we have the device nodes in a tree-like structure. If required, separate
acpi_power_get_bus() and acpi_power_set_bus() can be added in the future.
