1 STMicroelectronics STPMIC1 Voltage regulators
3 Regulator Nodes are optional depending on needs.
5 Available Regulators in STPMIC1 device are:
16 - vref_ddr for LDO Vref DDR
17 - boost for Buck BOOST
18 - pwr_sw1 for VBUS_OTG switch
19 - pwr_sw2 for SW_OUT switch
21 Switches are fixed voltage regulators with only enable/disable capability.
24 - st,mask-reset: mask reset for this regulator: the regulator configuration
25 is maintained during pmic reset.
26 - regulator-over-current-protection:
27 if set, all regulators are switched off in case of over-current detection
29 if not set, the driver only sends an over-current event.
30 - interrupts: index of current limit detection interrupt
31 - <regulator>-supply: phandle to the parent supply/regulator node
32 each regulator supply can be described except vref_ddr.
33 - regulator-active-discharge: can be used on pwr_sw1 and pwr_sw2.
