The voltage value for switchout converters is always reported as 0 uV.
When the switch is enabled, it's voltage is same as input supply.
Fix this by implementing get_value for switchout converters.

Information from the first range group is always used to calculate the
voltage returned for buck converters. This may result in wrong voltage
reported back to the regulator_get_value caller.

With the commit 4fcba5d556b4 ("regulator: implement basic reference
counter"), keeping regulator enablement in balance become more important.
Calling regulator_autoset multiple times on a fixed regulator increase
the enable count for each call, resulting in an unbalanced enable count.
Introduce a AUTOSET_DONE flag and use it to mark that autoset has run
for the regulator. Return -EALREADY on any subsequent call to autoset.
This fixes so that the enable count is only ever increased by one per
regulator for autoset.

A quick power cycle of a LDO regulator during dw-mmc signal voltage
change has shown that SD-card does not always get recognized.
Linux driver use an enable_time of 400us for LDO regulators. Apply a
500us delay when a LDO regulator is enabled to fix possible issues.

The commit 12df2c182ccb ("regulator: dt-bindings: fixed-regulator: allow
gpios property") in linux v6.3-rc1 added support for use of either a
gpios or gpio prop with a fixed-regulator.
This adds support for the new gpios prop to the fixed-regulator driver.
gpios prop is used by vcc3v3-pcie-regulator on Radxa ROCK 3 Model A.

In the imx8m power domain kernel driver, there is an extra udelay(5)
prior to requesting the domain to power up:
https://github.com/torvalds/linux/blob/v6.3/drivers/soc/imx/gpcv2.c#L347-L375
Haven't observed any issues due to the lack of this delay in U-Boot yet,
but better to align it with the kernel driver implementation.

Some devices share a regulator supply, when the first one will request
regulator disable, the second device will have it's supply cut off before
graciously shutting down. Hence there will be timeouts and other failed
operations.
Implement a reference counter mechanism similar with what is done in
Linux, to keep track of enable and disable requests, and only disable the
regulator when the last of the consumers has requested shutdown.

This driver reports the presence/absence of voltage on the PMIC's USB
VBUS pin. This information is used by the USB PHY driver. The
corresponding Linux driver uses the power supply class, which does not
exist in U-Boot. UCLASS_REGULATOR seems to be the closest match.

The default configuration of the PMIC behavior makes the PMIC
power cycle most regulators on WDOG_B assertion. This power
cycling causes the memory contents of OCRAM to be lost.
Some systems neeeds some memory that survives reset and
reboot, therefore this patch is created.
The implementation is taken almost verbatim from Linux commit
2364a64d0673f ("regulator: pca9450: Make warm reset on WDOG_B assertion")

This driver handles most voltage regulators found in X-Powers AXP PMICs.
It is based on, and intended to replace, the regulator driver in TF-A.
AXP PMIC regulators can be divided into 6 categories:
- Switches without voltage control => fully supported.
- Single linear range => fully supported.
- Two linear ranges, "step" and "2 * step" => fully supported.
- Two linear ranges, "step" and "5 * step" => only the first range is
supported. No boards are known to use the second range.
- Non-linear voltage values => fully supported.
- LDOs shared with GPIO pins => not supported.

If the bd718x7 is required, but PMIC_CHILDREN is disabled, this

Allowing PMIC_CHILDREN to be disabled in SPL saves some space and
still permits some read/write functions to access the PMIC in
early startup.
