19 This driver implements support for the Analog Devices ADT7411 chip. There may
20 be other chips that implement this interface.
22 The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an
23 SPI-compatible 4-wire interface. It provides a 10-bit analog to digital
24 converter which measures 1 temperature, vdd and 8 input voltages. It has an
25 internal temperature sensor, but an external one can also be connected (one
26 loses 2 inputs then). There are high- and low-limit registers for all inputs.
28 Check the datasheet for details.
33 ================ =================
34 in0_input vdd voltage input
35 in[1-8]_input analog 1-8 input
36 temp1_input temperature input
37 ================ =================
39 Besides standard interfaces, this driver adds (0 = off, 1 = on):
41 ============== =======================================================
42 adc_ref_vdd Use vdd as reference instead of 2.25 V
43 fast_sampling Sample at 22.5 kHz instead of 1.4 kHz, but drop filters
44 no_average Turn off averaging over 16 samples
45 ============== =======================================================
50 SPI, external temperature sensor and limit registers are not supported yet.
