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