I'll keep that in mind. Thanks.
GMT G751 is an I2C temperature sensor and thermal watchdog chip. It is
basically a clone of National Semiconductor LM75 chip:
root@thin:/sys# sensors
g762-i2c-0-3e
Adapter: mv64xxx_i2c adapter
fan1: 5461 RPM (div = 1)
g762-i2c-0-48
Adapter: mv64xxx_i2c adapter
fan1: 5461 RPM (div = 1)
g762-i2c-0-49
Adapter: mv64xxx_i2c adapter
fan1: 5461 RPM (div = 1)
g751-i2c-0-4c
Adapter: mv64xxx_i2c adapter
temp1: +30.5°C (high = +80.0°C, hyst = +75.0°C)
armada_thermal-virtual-0
Adapter: Virtual device
temp1: +34.2°C
Cheers,
