It seems that irq_chip_set_type_parent is not failing. By adding some
debug messages to kernel/irq/manage.c I found that irqd_get_trigger_type
returns IRQF_TRIGGER_RISING even though it should return
IRQF_TRIGGER_HIGH according to the device tree. Maybe this was fixed
between 6.10 and 6.12 but I need to analyze that again in more detail.

The trigger type is fixed up in mvebu_icu_irq_domain_translate(), but
that should be the same with the new code in mvebu_icu_translate().

Can you instrument mvebu_icu_translate() and validate that it is

    1) Invoked at all

    2) The type fixup is done:

       if (msi_data->subset_data->icu_group == ICU_GRP_SEI)
              *type = IRQ_TYPE_EDGE_RISING;

Thanks,
