/*
 * XCPM power management compatibility table with Darwin method.
 *
 * Please note that this table is only a sample and may need to be
 * adapted to fit your board's ACPI stack. For instance, both scope
 * and device name may vary (e.g. _SB_.PR00 instead of _PR_.CPU0).
 *
 * While the table contains several examples of CPU paths, you should
 * remove all the ones irrelevant for your board.
