PSTATE_DT_DEFINE

#define PSTATE_DT_DEFINE	(		_node,
			_config
	)

#include <include/zephyr/cpu_freq/pstate.h>

Value:

        const struct pstate PSTATE_DT_SYM(_node) = {                                               \
                .load_threshold = DT_PROP(_node, load_threshold),                                  \
                .config = _config,                                                                 \
