+         found in every PC or ACPI-based system, and some other boards.

+         Your system will need to define the platform device used by
+         this driver, otherwise it won't be accessible.  This means
+         you can safely enable this driver if you don't know whether
+         or not your board has this kind of hardware.
+
+         This driver can also be built as a module. If so, the module
+         will be called rtc-cmos.
