   *
   * 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.onsemi.com/PowerSolutions/product.do?id=ADM1025 

   *
   * 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.
