Optional properties:
- clock-output-names : Should contain name for output clock.
- rohm,reset-snvs-powered : Transfer BD718x7 to SNVS state at reset.
The BD718x7 supports two different HW states as reset target states. States
are called as SNVS and READY. At READY state all the PMIC power outputs go
down and OTP is reload. At the SNVS state all other logic and external
devices apart from the SNVS power domain are shut off. Please refer to NXP
i.MX8 documentation for further information regarding SNVS state. When a
reset is done via SNVS state the PMIC OTP data is not reload. This causes
power outputs that have been under SW control to stay down when reset has
switched power state to SNVS. If reset is done via READY state the power
outputs will be returned to HW control by OTP loading. Thus the reset
target state is set to READY by default. If SNVS state is used the boot
crucial regulators must have the regulator-always-on and regulator-boot-on
properties set in regulator node.

Fixed Voltage regulators
Required properties:
- compatible: Must be "regulator-fixed";
- regulator-name: Defined in regulator.txt as optional, but required here.
Optional properties:
- gpio: gpio to use for enable control
- startup-delay-us: startup time in microseconds
- enable-active-high: Polarity of GPIO is Active high
If this property is missing, the default assumed is Active low.
- gpio-open-drain: GPIO is open drain type.
If this property is missing then default assumption is false.
-vin-supply: Input supply name.
Any property defined as part of the core regulator
binding, defined in regulator.txt, can also be used.
However a fixed voltage regulator is expected to have the
regulator-min-microvolt and regulator-max-microvolt
to be the same.
Example:
abc: fixedregulator@0 {
compatible = "regulator-fixed";
regulator-name = "fixed-supply";
regulator-min-microvolt = <1800000>;

Regulator driver for MAX77650 PMIC from Maxim Integrated.
This module is part of the MAX77650 MFD device. For more details
see Documentation/devicetree/bindings/mfd/max77650.txt.
The regulator controller is represented as a sub-node of the PMIC node
on the device tree.
The device has a single LDO regulator and a SIMO buck-boost regulator with
three independent power rails.
Required properties:
--------------------
- compatible: Must be "maxim,max77650-regulator"
Each rail must be instantiated under the regulators subnode of the top PMIC
node. Up to four regulators can be defined. For standard regulator properties
refer to Documentation/devicetree/bindings/regulator/regulator.txt.
Available regulator compatible strings are: "ldo", "sbb0", "sbb1", "sbb2".
Example:
--------
regulators {
compatible = "maxim,max77650-regulator";
max77650_ldo: regulator@0 {
regulator-compatible = "ldo";
regulator-name = "max77650-ldo";
regulator-min-microvolt = <1350000>;
regulator-max-microvolt = <2937500>;
};
max77650_sbb0: regulator@1 {
regulator-compatible = "sbb0";
regulator-name = "max77650-sbb0";
regulator-min-microvolt = <800000>;
regulator-max-microvolt = <1587500>;
