Subject: [PATCH 04/29] rtc: mpc5121: let the core handle the alarm resolution
Date: Wed, 9 Mar 2022 17:22:35 +0100 [thread overview]
Message-ID: <20220309162301.61679-4-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20220309162301.61679-1-alexandre.belloni@bootlin.com>
Set RTC_FEATURE_ALARM_RES_MINUTE, so the core knows alarms have a
resolution of a minute. Also, the core will properly round down the alarm
instead of up.
