From c1aaaa1cb7c82fe53463fba4928405fddcc4ea27 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Wed, 5 Sep 2018 16:36:06 +0200 Subject: [PATCH] mfd: max8997: Disable interrupt handling for suspend/resume cycle Disable IRQs during suspend/resume cycle to ensure handling of wakeup interrupts (i.e. RTC wake alarm) after max8997_resume(). This way it can be properly handled when I2C bus is finally available. This pattern is also used in other MAX PMIC MFD drivers.
