This chip implements one local and two remote sensors. 23ba3d8588SLei YUThe chip also features offsets for the two remote sensors which get added to 24ba3d8588SLei YUthe input readings. The chip does all the scaling by itself and the driver 25ba3d8588SLei YUtherefore reports true temperatures that don't need any user-space adjustments. 26ba3d8588SLei YUTemperature is measured in degrees Celsius. 27ba3d8588SLei YUThe chip is wired over I2C/SMBus and specified over a temperature 28ba3d8588SLei YUrange of -40 to +125 degrees Celsius (for local sensor) and -40 to +127 29ba3d8588SLei YUdegrees Celsius (for remote sensors). 30ba3d8588SLei YUResolution for both the local and remote channels is 0.125 degree C. 31ba3d8588SLei YU 32ba3d8588SLei YUThe chip supports only temperature measurement. The driver exports 33ba3d8588SLei YUthe temperature values via the following sysfs files: 34ba3d8588SLei YU 35*b04f2f7dSMauro Carvalho Chehab**temp[1-3]_input, temp[2-3]_fault, temp[2-3]_offset, update_interval** 36
