This add regulator driver for Smartbond DA1469X SOC.
Driver can control VDD, V14, V18, V18P, V30 rails,
full voltage range supported by SOC is covered.
For VDD, V14, V18, V18P DCDC can be configured.
Special VDD_CLAMP (always on) and VDD_SLEPP are added
to allow configuration of VDD in sleep modes.

Add binding, include header, and driver for NXP VREF IP block.
NXP VREF is an internal voltage reference generator on some SOCs
that fits well with the regulator API in zephyr.

Add basic support of 'regulator-gpio'. For now, it is support
only controling voltage and driver presents only six functions:
* enable and disable the regulator;
* set and get voltage;
* count and list of voltage(s).

AXP192 is a small and simple power management IC featuring different
LDOs, DCDCs, AINs and also GPIOs. It also offers functionaltiy for
battery management.
This change includes the basic regulator driver functionaltiy for
LDO2-3 and DCDC1-3 as well as the mfd driver layer. Further drivers
for GPIO and ADC will follow.
Drivers have been developed and tested on M5StackCore2, an ESP32-based
board. Support for M5StackCore2 is still in progress.

Add a new regulator driver for Analog Devices ADP5360. While it is a MFD
device, only support for BUCK/BUCKBOOST regulators is added in this
patch.

While nPM1100 is to be operated in fixed configuration for some
applications, it has some degree of configuration via GPIOs. For
example, mode (auto/PWM) can be configured via MODE pin. VBUS current
can also be adjusted using ISET pin, even though there is no API yet to
limit the PMIC input current.
This patch adds a new regulator class driver for nPM1100 PMIC, so that
it can be used with the standard regulator API when needed.

Add FFF-based fake regulator driver. This driver can be used as a stub
or mock in testing.

Drop the async enable function. This feature is rarely/never used,
complicates driver design, and doesn't really follow the sync/async API
design/naming used in other areas. In the future we can introduce
regulator_enable_async if needed, with support from the driver class (no
onoff). Note that drivers like PCA9420 did not implement any
asynchronous behavior. regulator-fixed implemented in the past
asynchronous behavior using work queues, an overkill for most GPIO
driven regulators. Let's keep things simple for now and extend the API
when needed, based on specific usecases.
In the current implementation, reference counting is managed by the
driver class. \isr-ok attribute is dropped, since calls are potentially
blocking. Note that drivers like PCA9420 already violated such rule.

The "pmic" driver was in reality a driver for NXP PCA9420 PMIC. There's
no "universal PMIC". While the driver may work for other NXP PMICs, it
is clearly not generic for other vendors PMIC.

Add shell for interacting with regulator devices, to enable
users to test power management settings quickly and verify that their
regulator is functioning as expected. Also allows users to interact with
regulator PMIC devices

This commit adds a generic i2c regulator driver, and enables the NXP
PCA9420 PMIC IC using this driver. The regulator driver also exposes an
additional API in include/drivers/regulator/consumer.h, which allows
drivers to implement support for adjusting voltage levels and current
limits, if their device supports it.
