     26    description:
     27      The LTC2947 uses either a trimmed internal oscillator or an external clock
     28      as the time base for determining the integration period to represent time,
     29      charge and energy. When an external clock is used, this property must be
     30      set accordingly.

     34    description:
     35      This property controls the polarity of current that is accumulated to
     36      calculate charge and energy so that, they can be only accumulated for
     37      positive current for example. Since there are two sets of registers for
     38      the accumulated values, this entry can also have two items which sets
     39      energy1/charge1 and energy2/charger2 respectively. Check table 12 of the
     40      datasheet for more information on the supported options.

     55  adi,gpio-out-pol:
     56    description:
     57      This property controls the GPIO polarity. Setting it to one makes the GPIO
     58      active high, setting it to zero makets it active low. When this property
     59      is present, the GPIO is automatically configured as output and set to
     60      control a fan as a function of measured temperature.

     65  adi,gpio-in-accum:
     66    description:
     67      When set, this property sets the GPIO as input. It is then used to control
     68      the accumulation of charge, energy and time. This function can be
     69      enabled/configured separately for each of the two sets of accumulation
     70      registers. Check table 13 of the datasheet for more information on the
     71      supported options. This property cannot be used together with
     72      adi,gpio-out-pol.
