Kernel driver `mtp008.o' ========================= Status: Complete; Beta. This chip is quite configurable and many settings cannot be done through the driver. Hopefully the BIOS settings will be correct for most motherboards. Supported chips: * Myson MTP008 Prefix `mtp008' Addresses scanned: I2C 0x2c - 0x2e (inclusive) Datasheet: Publicly available at the Myson website Author: Kris Van Hees Description ----------- The Myson MTP008 is similar in function to the Winbond W83781D and the National Semi LM78. See documentation for those chips for an overview. The MTP008 chip has several pins that are configurable. The three temperature sensors are configurable via the driver using either the /proc entries or 'set sensorx y' statements in /etc/sensors.conf. One temperature input is always temp1, and the sensor type is configured with the sensor1 entry in /proc. One input is either in4 or temp2, and is configured with the sensor2 entry. One input is either in5 or temp3, and is configured with the sensor3 entry. For example, on the Tyan S1824D motherboard, AIN4 is configured as PII temp sensor 2 and AIN5 is hooked up to the -12V sensing circuit. Other Tyan motherboards (the 2510 Thunder and the Tiger 200) appear to have different configurations. For the 2510, which has two MTP008 chips, each with a different configuration, follow the instructions in the mtp008 section of etc/sensors.conf.eg to configure 'sensors' correctly. The PWM outputs are configurable but not via the driver. The Fan input types (2 wire or 3 wire) are configurable but not via the driver. The driver now preserves pin settings that the BIOS configures. If your BIOS did it right then the driver should work great. The MTP008 has sensor type selection in /proc like the Winbond W83782D. However, the appropriate values used to make the selection are different. To select a sensor type, echo the value to the /proc entry, for example: echo 1 > /proc/sys/dev/sensors/mtp008-i2c-0-2d/sensor1 Or, use /etc/sensors.conf and add a line 'set sensor1 1', for example. Hopefully the BIOS has set these already. Sensor selection is as follows: Value Function Valid on sensors ----- -------- ---------------- 1 Analog input (not for temperature sensing) 2,3 2 Thermistor 1,2,3 3 Pentium diode 1,2 Maintainer ----------------- Send requests to the sensors@stimpy.netroedge.com mailing list.
