15 This driver implements support for the Analog Devices ADT7411 chip. There may
16 be other chips that implement this interface.
18 The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an
19 SPI-compatible 4-wire interface. It provides a 10-bit analog to digital
20 converter which measures 1 temperature, vdd and 8 input voltages. It has an
21 internal temperature sensor, but an external one can also be connected (one
22 loses 2 inputs then). There are high- and low-limit registers for all inputs.
24 Check the datasheet for details.
29 in0_input - vdd voltage input
30 in[1-8]_input - analog 1-8 input
31 temp1_input - temperature input
33 Besides standard interfaces, this driver adds (0 = off, 1 = on):
35 adc_ref_vdd - Use vdd as reference instead of 2.25 V
36 fast_sampling - Sample at 22.5 kHz instead of 1.4 kHz, but drop filters
37 no_average - Turn off averaging over 16 samples
42 SPI, external temperature sensor and limit registers are not supported yet.
