| Subject: ARM: dts: Fix duovero smsc interrupt for suspend |
| |
| From: Tony Lindgren <tony@atomide.com> |
| |
| [ 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. |
| |
