 *
 * The ADM1025 is a sensor chip made by Analog Devices. It reports up to 6
 * voltages (including its own power source) and up to two temperatures
 * (its own plus up to one external one). Voltages are scaled internally
 * (which is not the common way) with ratios such that the nominal value
 * of each voltage correspond to a register value of 192 (which means a
 * resolution of about 0.5% of the nominal value). Temperature values are
 * reported with a 1 deg resolution and a 3 deg accuracy. Complete
 * datasheet can be obtained from Analog's website at:
 *   http://www.analog.com/Analog_Root/productPage/productHome/0,2121,ADM1025,00.html
 *
 * This driver also supports the ADM1025A, which differs from the ADM1025
 * only in that it has "open-drain VID inputs while the ADM1025 has
 * on-chip 100k pull-ups on the VID inputs". It doesn't make any
 * difference for us.
 *
 * This driver also supports the NE1619, a sensor chip made by Philips.
 * That chip is similar to the ADM1025A, with a few differences. The only
 * difference that matters to us is that the NE1619 has only two possible
 * addresses while the ADM1025A has a third one. Complete datasheet can be
 * obtained from Philips's website at:
 *   http://www.semiconductors.philips.com/pip/NE1619DS.html
 *
 * Since the ADM1025 was the first chipset supported by this driver, most
 * comments will refer to this chipset, but are actually general and
 * concern all supported chipsets, unless mentioned otherwise.
