The Gateworks System Controller (GSC) is a device present across various
|
||||
Gateworks product families that provides a set of system related features
|
||||
such as the following (refer to the board hardware user manuals to see what
|
||||
features are present)
|
||||
- Watchdog Timer
|
||||
- GPIO
|
||||
- Pushbutton controller
|
||||
- Hardware monitor with ADC's for temperature and voltage rails and
|

Kernel driver gsc-hwmon
|
||||
=======================
|
||||
|
||||
Supported chips: Gateworks GSC
|
||||
Datasheet: http://trac.gateworks.com/wiki/gsc
|
||||
Author: Tim Harvey <tharvey@gateworks.com>
|
||||
|
||||
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.
