As per TRM[0] Section 8.7.1 "TPS6594-Q1 Registers", LDOx_Vout
bit 6-1, define the NVM voltage settings.
Along side table 8-4 of above TRM, shows voltage to value mapping.
Driver wrongly using bits 5-1 to calculate voltage, and to convert
voltage to value driver was using buck's calculation.
So fix those calculation.

1. Use runtime voltage selection for LD/OD/ND mode.
2. According to latest PE/TE report, the voltages of VDD_SOC for
LD and ND mode need add 50mv margin, so LD voltage is 0.75v->0.8v,
ND voltage is 0.8v->0.85v.

This adds support for RK806, only the SPI variant has been tested.
The communication "protocol" over SPI is the following:
- write three bytes:
- 1 byte: [0:3] length of the payload, [6] Enable CRC, [7] Write
- 1 byte: LSB register address
- 1 byte: MSB register address
- write/read length of payload
The CRC is always disabled for now.
The RK806 technically supports I2C as well, and this should be able to
support it without any change, but it wasn't tested.
The DT node name prefix for the buck converters has changed in the
Device Tree and is now dcdc-reg. The logic for buck converters is
however manageable within the current logic inside the rk8xx regulator
driver. The same cannot be said for the NLDO and PLDO.
Because pmic_bind_children() parses the DT nodes and extracts the LDO
index from the DT node name, NLDO and PLDO will have overlapping
indices. Therefore, we need a separate logic from the already-existing
ldo callbacks. Let's reuse as much as possible though.

These headers follow the pattern:
| #if CONFIG_IS_ENABLED(FANCY_FEATURE)
| void foo(void);
| #else
| static inline void foo(void) { return -ENOSYS; }
| #endif
In the #else path ENOSYS is used, however linux/errno.h is not included.
If errno.h has not been included already the compiler errors out even
if the inline function is not referenced.
Make those headers self contained.

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.

power cycle most regulators on WDOG_B assertion. This power
cycling causes the memory contents of OCRAM to be lost.

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.
This patch parallels the work done in the following patch series:

Depending on backup register value, U-Boot SPL maintains the debug unit
powered-on for debugging purpose; only BUCK1 is required for powering
the debug unit, so revert the setting for all the other power lanes,
except BUCK3 that has to be always on.
To be functional this patch requires a modification in the debugger
,openocd for example, to update the STM32MP15 backup register when it is
required to debug SPL after reset. After deeper analysis this behavior
will be never supported in tools so the associated code, will be never
used and the associated code can be removed.

All devices based on ST-Ericsson Ux500 use a PMIC similar to AB8500
(Analog Baseband). There is AB8500, AB8505, AB9540 and AB8540
although in practice only AB8500 and AB8505 are relevant since the
platforms with AB9540 and AB8540 were cancelled and never used in
production.
In general, the AB8500 PMIC uses I2C as control interface, where the
different register banks are represented as separate I2C devices.
However, in practice AB8500 is always connected to a special I2C bus
on the DB8500 SoC that is controlled by the power/reset/clock
management unit (PRCMU) firmware.
Add a simple driver that allows reading/writing registers of the
AB8500 PMIC. The driver directly accesses registers from the PRCMU
parent device (represented by syscon in U-Boot). Abstracting it
further (e.g. with the i2c uclass) would not provide any advantage
because the PRCMU I2C bus is always just connected to AB8500 and
vice-versa.
The ab8500.h header is mostly taken as-is from Linux (with some
minor adjustments) to allow using similar code in both Linux and
U-Boot.
