    irqchip/crossbar: Restore the irq_set_type() mechanism · e269ec42
    Grygorii Strashko authored
    The conversion of the crossbar irqchip to hierarchical irq domains
    failed to provide a mechanism to properly set the trigger type of an
    interrupt.
    
    The crossbar irq chip itself has no mechanism and therefor no
    irq_set_type() callback. The code before the conversion relayed the
    trigger configuration directly to the underlying GIC.
    
    Restore the correct behaviour by setting the crossbar irq_set_type
    callback to irq_chip_set_type_parent(). This propagates the
    set_trigger() call to the underlying GIC irqchip.
