SPDX-License-Identifier: GPL-2.0 + +Kernel driver gsc-hwmon +======================= + +Supported chips: Gateworks GSC +Datasheet: http://trac.gateworks.com/wiki/gsc +Author: Tim Harvey + +Description: +------------ + +This driver supports hardware monitoring for the temperature sensor, +various ADC's connected to the GSC, and optional FAN controller available +on some boards. + + +Voltage Monitoring +------------------ + +The voltage inputs are scaled either internally or by the driver depending +on the GSC version and firmware. The values returned by the driver do not need +further scaling. The voltage input labels provide the voltage rail name: + +inX_input Measured voltage (mV). +inX_label Name of voltage rail. + + +Temperature Monitoring +---------------------- + +Temperatures are measured with 12-bit or 10-bit resolution and are scaled +either internally or by the driver depending on the GSC version and firmware. +The values returned by the driver reflect millidegree Celcius: + +tempX_input Measured temperature. +tempX_label Name of temperature input. + + +PWM Output Control +------------------ + +The GSC features 1 PWM output that operates in automatic mode where the +PWM value will be scalled depending on 6 temperature boundaries. +The tempeature boundaries are read-write and in millidegree Celcius and the +read-only PWM values range from 0 (off) to 255 (full speed). +Fan speed will be set to minimum (off) when the temperature sensor reads +less than pwm1_auto_point1_temp and maximum when the temperature sensor +equals or exceeds pwm1_auto_point6_temp. + +pwm1_auto_point[1-6]_pwm PWM value. +pwm1_auto_point[1-6]_temp Temperature boundary. + -- cgit v1.2.3
