From 454ba154a62c8806e82a3581c5233a5176cd7dd7 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Thu, 21 Jan 2021 00:16:02 +0300 Subject: rtc: tps65910: Support wakeup-source property TPS65910 is a PMIC MFD device and RTC is one of its functions. The wakeup-source DT property is specified for the parent MFD device and we need to use this property for the RTC in order to allow to use RTC alarm for waking up system from suspend by default, instead of requiring user to enable wakeup manually via sysfs.
