+What: /sys/devices/platform/samsung/performance_level
+Date: January 1, 2010
+KernelVersion: 2.6.33
+Contact: Greg Kroah-Hartman <gregkh@suse.de>
+Description: Some Samsung laptops have different "performance levels"
+ that are can be modified by a function key, and by this
+ sysfs file. These values don't always make a whole lot
+ of sense, but some users like to modify them to keep
+ their fans quiet at all costs. Reading from this file
+ will show the current performance level. Writing to the
+ file can change this value.
+ Valid options:
+ "silent"
+ "normal"
+ "overclock"
+ Note that not all laptops support all of these options.
+ Specifically, not all support the "overclock" option,
+ and it's still unknown if this value even changes
+ anything, other than making the user feel a bit better.

- * PCF8563 RTC
- *
- * From Phillips' datasheet:
- *
- * The PCF8563 is a CMOS real-time clock/calendar optimized for low power
- * consumption. A programmable clock output, interrupt output and voltage
- * low detector are also provided. All address and data are transferred
- * serially via two-line bidirectional I2C-bus. Maximum bus speed is
- * 400 kbits/s. The built-in word address register is incremented
- * automatically after each written or read byte.
