From e99653afeb9585350644c5ae4b0ca987cbe8d053 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Wed, 9 Mar 2022 17:22:53 +0100 Subject: [PATCH] rtc: add new RTC_FEATURE_ALARM_WAKEUP_ONLY feature Some RTCs have an IRQ pin that is not connected to a CPU interrupt but rather directly to a PMIC or power supply. In that case, it is still useful to be able to set alarms but we shouldn't expect interrupts.
