-Kernel driver fscher
-====================
-
-Supported chips:
- * Fujitsu-Siemens Hermes chip
- Prefix: 'fscher'
- Addresses scanned: I2C 0x73
-
-Authors:
- Reinhard Nissl <rnissl@gmx.de> based on work
- from Hermann Jung <hej@odn.de>,
- Frodo Looijaard <frodol@dds.nl>,
- Philip Edelbrock <phil@netroedge.com>
-
-Description
------------
-
-This driver implements support for the Fujitsu-Siemens Hermes chip. It is
-described in the 'Register Set Specification BMC Hermes based Systemboard'
-from Fujitsu-Siemens.
-
-The Hermes chip implements a hardware-based system management, e.g. for
-controlling fan speed and core voltage. There is also a watchdog counter on
-the chip which can trigger an alarm and even shut the system down.
-
-The chip provides three temperature values (CPU, motherboard and
-auxiliary), three voltage values (+12V, +5V and battery) and three fans
-(power supply, CPU and auxiliary).
-
-Temperatures are measured in degrees Celsius. The resolution is 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). The value
-can be divided by a programmable divider (1, 2 or 4) which is stored on
-the chip.
-
-Voltage sensors (also known as "in" sensors) report their values in volts.
-
-All values are reported as final values from the driver. There is no need
-for further calculations.
-
-
-Detailed description
---------------------
-
-Below you'll find a single line description of all the bit values. With
-this information, you're able to decode e. g. alarms, wdog, etc. To make
-use of the watchdog, you'll need to set the watchdog time and enable the
-watchdog. After that it is necessary to restart the watchdog time within
-the specified period of time, or a system reset will occur.

-Limitations
------------
-
-* Measuring fan speed
-It seems that the chip counts "ripples" (typical fans produce 2 ripples per
-rotation while VERAX fans produce 18) in a 9-bit register. This register is
-read out every second, then the ripple prescaler (2, 4 or 8) is applied and
-the result is stored in the 8 bit output register. Due to the limitation of
-the counting register to 9 bits, it is impossible to measure a VERAX fan
-properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
-fan produces 1080 ripples per second which causes the counting register to
-overflow twice, leading to only 186 RPM.
-
-* Measuring input voltages
-in2 ("battery") reports the voltage of the onboard lithium battery and not
-+3.3V from the power supply.
-
-* Undocumented features
-Fujitsu-Siemens Computers has not documented all features of the chip so
-far. Their software, System Guard, shows that there are a still some
-features which cannot be controlled by this implementation.
