-Subject: [PATCH 34/96] rtc: rs5c372: support alarms up to 1 week
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The Ricoh R2221x, R2223x, RS5C372, RV5C387A chips can handle 1 week
-alarms.
-
-Read the "wday" alarm register and convert it to a date to support up 1
-week in our driver.
