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

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