910c7a881f pmic: pca9450: Make warm reset on WDOG_B assertion
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")

27a93dd4a9 power: regulator: Add a driver for AXP PMIC regulators
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.

8edf7ac09f power: regulator: fix autoset error handling
If a regulator does not support .set_suspend_enable or
.set_suspend_value then ret is set to ENOSYS early in the function.

The most serious impact of this is that when no automatic setting of
voltage is needed then the final regulator_set_enable() is skipped
because ret has not been cleared.

It seems that the error handling for regulator_set_suspend_value() is
also wrong as if this succeeds then the normal boot-on checks are still
required, and again ENOSYS needs special treatment here.

For Rockchip boards with the all rk8xx series PMICs (excluding the
rk808), it is sometimes desirable to not boot whenever the device is
plugged in. An example would be for the Odroid Go Advance.

This provides a configurable option to check the PMIC says it was
powered because of a plug-in event. If the value is 1 and this option
is selected, the device shuts down shortly after printing a message
to console stating the reason why it's shutting down. Powering up the
board with the power button is not affected.

2add051175 pmic: pca9450: Add optional SD_VSEL GPIO for LDO5
LDO5 has two separate control registers. LDO5CTRL_L is used if the
input signal SD_VSEL is low and LDO5CTRL_H if it is high.
The current driver implementation only uses LDO5CTRL_H. To make this
work on boards that have SD_VSEL connected to a GPIO, we add support
for specifying an optional GPIO and setting it to high at probe time.

In the future we might also want to add support for boards that have
SD_VSEL set to a fixed low level. In this case we need to change the
driver to be able to use the LDO5CTRL_L register.

This is a port of the same change in the Linux kernel:
