Subject: [PATCH] drivers: irqchip: pdc: setup all edge interrupts as rising edge at GIC
Date: Thu, 27 Sep 2018 11:18:10 -0600 [thread overview]
Message-ID: <20180927171810.22968-1-ilina@codeaurora.org> (raw)
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.
