could be:
https://github.com/torvalds/linux/blob/master/drivers/irqchip/irq-gic-v3.c#L1145

		struct irq_fwspec ppi_fwspec = {
			.fwnode		= gic_data.fwnode,
			.param_count	= 3,
			.param		= {
				[0]	= 1,
				[1]	= i,
				[2]	= IRQ_TYPE_NONE, <--
			},
		};

		irq = irq_create_fwspec_mapping(&ppi_fwspec);
