From 5ff811604f93bdd2650beed80b48c2ca16c6fba6 Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Thu, 29 Sep 2022 10:19:10 -0600 Subject: ACPI: resources: Add wake_capable parameter to acpi_dev_irq_flags ACPI IRQ/Interrupt resources contain a bit that describes if the interrupt should wake the system. This change exposes that bit via a new IORESOURCE_IRQ_WAKECAPABLE flag. Drivers should check this flag before arming an IRQ to wake the system.
