| 13 | The Power On device for Qualcomm PM8xxx is MFD supporting pwrkey |
| 14 | and resin along with the Android reboot-mode. |
| 15 | |
| 16 | This DT node has pwrkey and resin as sub nodes. |

| 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. |
