Macros
#define	IRQ_CONNECT(irq_p, priority_p, isr_p, isr_param_p, flags_p)
	Initialize an interrupt handler.
#define	IRQ_DIRECT_CONNECT(irq_p, priority_p, isr_p, flags_p)
	Initialize a 'direct' interrupt handler.
#define	ISR_DIRECT_HEADER()
	Common tasks before executing the body of an ISR.
#define	ISR_DIRECT_FOOTER(check_reschedule)
	Common tasks before exiting the body of an ISR.
#define	ISR_DIRECT_PM()
	Perform power management idle exit logic.
#define	ISR_DIRECT_DECLARE(name)
	Helper macro to declare a direct interrupt service routine.
#define	irq_lock()
	Lock interrupts.
#define	irq_unlock(key)
	Unlock interrupts.
#define	irq_enable(irq)
	Enable an IRQ.
#define	irq_disable(irq)
	Disable an IRQ.
#define	irq_is_enabled(irq)
	Get IRQ enable state.
#define	K_IRQ_ACTIVE_NONE   UINT_MAX
	Value returned by k_irq_get_active() outside interrupt context.
