28      Specifies the SPMI base address for the PON (power-on) peripheral.  For
29      PMICs that have the PON peripheral (GEN3) split into PON_HLOS and PON_PBS
30      (e.g. PMK8350), this can hold addresses of both PON_HLOS and PON_PBS
31      peripherals.  In that case, the PON_PBS address needs to be specified to
32      facilitate software debouncing on some PMIC.
