From 99ab61cc8b75566899bd61864f0ff9b7f6eef41e Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 12 Jun 2020 10:19:50 -0700 Subject: [PATCH] ARM: dts: Fix duovero smsc interrupt for suspend [ Upstream commit 9cf28e41f9f768791f54ee18333239fda6927ed8 ] While testing the recent suspend and resume regressions I noticed that duovero can still end up losing edge gpio interrupts on runtime suspend. This causes NFSroot easily stopping working after resume on duovero. Let's fix the issue by using gpio level interrupts for smsc as then the gpio interrupt state is seen by the gpio controller on resume.
