Wong)15 16Description17-----------18 19This driver implements support for the Analog Devices ADT7411 chip. There may20be other chips that implement this interface.21 22The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an23SPI-compatible 4-wire interface. It provides a 10-bit analog to digital24converter which measures 1 temperature, vdd and 8 input voltages. It has an25internal temperature sensor, but an external one can also be connected (one26loses 2 inputs then). There are high- and low-limit registers for all inputs.27 28Check the datasheet for details.29 30sysfs-Interface31---------------32 33================ =================34in0_input vdd voltage input35in[1-8]_input analog 1-8 input36temp1_input temperature input37================ =================38 39Besides standard interfaces, this driver adds (0 = off, 1 = on):40 41 ============== =======================================================42 adc_ref_vdd Use vdd as reference instead of 2.25 V43 fast_sampling Sample at 22.5 kHz instead of 1.4 kHz, but drop filters44 no_average Turn off averaging over 16 samples45 ============== =======================================================46 47Notes48-----49 50SPI, external temperature sensor and limit registers are not supported yet.51
