From 4a43d686fe336cc0e955c4400ba4d3fcff788786 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Sat, 28 Sep 2013 19:52:51 +0200 Subject: of/irq: Pass trigger type in IRQ resource flags Some drivers might rely on availability of trigger flags in IRQ resource, for example to configure the hardware for particular interrupt type. However current code creating IRQ resources from data in device tree does not configure trigger flags in resulting resources. This patch tries to solve the problem, based on the fact that irq_of_parse_and_map() configures the trigger based on DT interrupt specifier and IRQD_TRIGGER_* flags are consistent with IORESOURCE_IRQ_*, and we can get correct trigger flags by calling irqd_get_trigger_type() after mapping the interrupt.
