From a850717dc7e3aaacbf3f85247d868ab198ad0a14 Mon Sep 17 00:00:00 2001 From: Harsha Priya Date: Wed, 25 Apr 2018 13:57:55 -0700 Subject: arch/x86/acpi_device: Add macros to define gpio with wake flag This patch adds new macros to define gpio with an option to either enable irq wake (mark it as ExclusiveAndWake flag in SSDT) or disable it (mark it as just Exclusive flag in SSDT).
