Wong) 11 12Description 13----------- 14 15This driver implements support for the Analog Devices ADT7411 chip. There may 16be other chips that implement this interface. 17 18The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an 19SPI-compatible 4-wire interface. It provides a 10-bit analog to digital 20converter which measures 1 temperature, vdd and 8 input voltages. It has an 21internal temperature sensor, but an external one can also be connected (one 22loses 2 inputs then). There are high- and low-limit registers for all inputs. 23 24Check the datasheet for details. 25 26sysfs-Interface 27--------------- 28 29in0_input - vdd voltage input 30in[1-8]_input - analog 1-8 input 31temp1_input - temperature input 32 33Besides standard interfaces, this driver adds (0 = off, 1 = on): 34 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 38 39Notes 40----- 41 42SPI, external temperature sensor and limit registers are not supported yet. 43
