17fd67aedd power: pmic: tps65941: Update compatible to aling with kernel DT
Linux kernel driver drivers/mfd/tps6594-i2c.c is using different
name for compatible for tps6594 family PMIC.
After sync of Linux kernel DT to u-boot for TI platforms
J7200, J721S2 and J784S4 PMIC is no longer getting probed.

So updating compatible field to align with Linux driver and DT.

f172575d92 power: rk8xx: add support for RK806
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.

f047e4ab97 regulator: rk8xx: add indirection level for some ldo callbacks

separately. U-boot's dev_read_addr() doesn't know how to handle this, so
use ofnode_read_u32_index() to get just the USID.

The Qcom pmic driver doesn't have support for GSID handling, so just
ignore the second value for now.

ffb02942fa sunxi: board: simplify early PMIC setup conditions
So far we have a convoluted #ifdef mesh that guards the early AXP PMIC
setup in board.c. That combination of &&, || and negations is very hard
to read, maintain and especially to extend.

Fortunately we have those same conditions already modelled in the
Kconfig file, so they are actually redundant. On top of that the real
reason we have those preprocessor guards in the first place is about the
symbols that are *conditionally* defined: without #ifdefs the build
would break because of them being undefined for many boards.

To simplify this, just change the guards to actually look at the symbols
needed, so CONFIG_AXP_xxx_VOLT instead of CONFIG_AXPyyy_POWER.
This drastically improves the readability of this code, and makes adding
PMIC support a pure Kconfig matter.

Doing this revealed one bug in Kconfig: there is no axp_set_dcdc4() for
the AXP818, even though CONFIG_AXP_DCDC4_VOLT includes that PMIC.
Since the AXP818 wasn't included when calling axp_set_dcdc4() in board.c,
this wasn't an issue, but becomes one now, so also remove the AXP818 from
the DCDC4 Kconfig symbol.

c8ebcc921f power: pmic: rk8xx: Fix power-on source check in SPL
The commit 30975fb73d51 ("rockchip: Add option to prevent booting on
power plug-in") introduce an option to prevent booting a device when the
device was powered on due to power plug-in instead of pressing a power
button.

This feature works by checking the power-on source during PMIC probe
and powers off the device if power-on source was power plug-in.
This check currently runs very late at PMIC probe in U-Boot proper.

Fix so that the power-on source check can work at probe time in SPL.
Also enable probe after bind and remove the PMIC banner in SPL.

With this we can use ROCKCHIP_RK8XX_DISABLE_BOOT_ON_POWERON and
SPL_PMIC_RK8XX to power off the device very quickly after TPL instead
of after TF-A and U-Boot proper has been loaded and run.

bb657ffdd6 regulator: rk8xx: Return correct voltage for switchout converters
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.

d99fb64a98 power: regulator: Only run autoset once for each regulator
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.

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.
