[PATCH v4 3/8] dt-bindings: regulator: document stpmic1 pmic regulators
From: pascal paillet
The STPMIC1 regulators supply power to the application processor as well as
to the external system peripherals such as DDR, Flash memories and system
devices.

+STMicroelectronics STPMIC1 Voltage regulators
+
+Regulator Nodes are optional depending on needs.
+
+Available Regulators in STPMIC1 device are:
+ - buck1 for Buck BUCK1
+ - buck2 for Buck BUCK2
+ - buck3 for Buck BUCK3
+ - buck4 for Buck BUCK4
+ - ldo1 for LDO LDO1
+ - ldo2 for LDO LDO2
+ - ldo3 for LDO LDO3
+ - ldo4 for LDO LDO4
+ - ldo5 for LDO LDO5
+ - ldo6 for LDO LDO6
+ - vref_ddr for LDO Vref DDR
+ - boost for Buck BOOST
+ - pwr_sw1 for VBUS_OTG switch
+ - pwr_sw2 for SW_OUT switch
+
+Switches are fixed voltage regulators with only enable/disable capability.
+
+Optional properties:
+- st,mask-reset: mask reset for this regulator: the regulator configuration
+ is maintained during pmic reset.
+- regulator-pull-down: enable high pull down
+ if not specified light pull down is used
+- regulator-over-current-protection:
+if set, all regulators are switched off in case of over-current detection
+on this regulator,
+if not set, the driver only sends an over-current event.
+- interrupt-parent: phandle to the parent interrupt controller
+- interrupts: index of current limit detection interrupt
+- -supply: phandle to the parent supply/regulator node
+ each regulator supply can be described except vref_ddr.
+
+Example:
+regulators {
+ compatible = "st,stpmic1-regulators";
+
+ ldo6-supply = <>;
+
+ vdd_core: buck1 {
+ regulator-name = "vdd_core";
+ interrupts = ;
+ interrupt-parent = <>;
+ st,mask-reset;
+ regulator-pull-down;
+ regulator-min-microvolt = <70>;
+ regulator-max-microvolt = <120>;
+ };
+
+ v3v3: buck4 {
+ regulator-name = "v3v3";
+ interrupts = ;
+ interrupt-parent = <>;
+
+ regulator-min-microvolt = <330>;
+ regulator-max-microvolt = <330>;
+ };
+
+ v1v8: ldo6 {
+ regulator-name = "v1v8";
+ regulator-min-microvolt = <180>;
+ regulator-max-microvolt = <180>;
