           If you say Y here you will get support for the ST M41T60
           and M41T80 RTC chips series. Currently, the following chips are
           supported: M41T62, M41T65, M41T80, M41T81, M41T82, M41T83, M41ST84,
-          M41ST85, and M41ST87.
+          M41ST85, M41ST87, and MicroCrystal RV4162.
 
           This driver can also be built as a module. If so, the module
           will be called rtc-m41t80.
