Ultimately the GIC trigger type has to be
something. Is it fixed or passed thru? If the latter, just use 0
(IRQ_TYPE_NONE) if the GIC trigger mode is not fixed. Having some sort
of translation of the trigger is pretty common.
Yes, as explained above, the SIRQ controller performs indeed the
translation of the incoming signal. So if I understand correctly, your
suggestion would be to use the following inside the sirq node:
interrupts = <GIC_SPI 13 IRQ_TYPE_NONE>, /* SIRQ0 */

Please don't. If you are describing a GIC interrupt, use a
trigger that actually exists. Given that you have a 1:1
mapping between input and output, just encode the output
trigger that matches the input.
