 * C. +1.5V ICH (only if BOTH pin 28/29 are set to +1.5V)
 * D. +1.5V 3GPIO (only if BOTH pin 28/29 are set to +1.5V)
 *
 * Each of these 13 has a factor to convert raw to voltage.  Even better,
 * the pins can be connected to other sensors (tach/gpio/hot/etc), which
 * makes the bookkeeping tricky.
 *
 * Some, but not all, of these voltages have low/high limits.
