          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.
