Moved, renamed, and deleted files
The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

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. + +sysfs-Interface +--------------- + +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 + +Notes +----- + +SPI, external temperature sensor and limit registers are not supported yet. |
