Subject: [PATCH v2 8/9] rtc: pcf2123: implement .alarm_irq_enable
Date: Wed, 14 Aug 2019 17:10:01 +0200
Message-ID: <20190814151002.7324-8-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20190814151002.7324-1-alexandre.belloni@bootlin.com>

Implement .alarm_irq_enable so it is possible to use RTC_ALM_SET,
RTC_AIE_ON and RTC_AIE_OFF.
