4.19-stable review patch. If anyone has any objections, please let me know.

From: Lina Iyer <ilina@xxxxxxxxxxxxxx>
[ Upstream commit 7bae48b22c8d38c5cd50f52b6e15d134e2bb3935 ]
The PDC irqchp can convert a falling edge or level low interrupt to a
rising edge or level high interrupt at the GIC. We just need to setup
the GIC correctly. Set up the interrupt type for the IRQ_TYPE_EDGE_BOTH
as IRQ_TYPE_EDGE_RISING at the GIC.
