If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Anson Huang commit 4699ccbf8cf2f962031b88de7851f610030e5c17 upstream. GPC irq domain is a child domain of GIC, now all of platform irqs are inside GPC domain, during the module populate, all devices irq should have correct type setting in GIC, however, there is no .irq_set_type callback setting in GPC, so the irq_set_type will be skipped and cause all irqs' type in /proc/interrupt are "edge" which mismatch with irq type setting in dtb file. Since GPC has no irq type setting, so just tell kernel to use irq_chip_set_type_parent.
