4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Grygorii Strashko <grygorii.strashko@xxxxxx>
commit e269ec42328783e51be08c191aa935dba56141fc upstream.
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.
