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