Subject: [PATCH 22/29] rtc: add new RTC_FEATURE_ALARM_WAKEUP_ONLY feature
Date: Wed, 9 Mar 2022 17:22:53 +0100 [thread overview]
Message-ID: <20220309162301.61679-22-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20220309162301.61679-1-alexandre.belloni@bootlin.com>
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.
