df1fa2718f drivers: power: regulator: tps65941_regulator: Add support for 3Phase buck
Buck regulator 1, 2 and 3 of TPS6594132 on j721e-sk is in 3 Phase
confguration, in-order to support this, add configuring 3 Phase buck
in tps65941 while driver probing.

1b7f00eb1f regulator: bd718x7: Bypass bogus warnings
When regulator consumer attempts to set enabled DVS regulator voltage,
the driver aborts with "Only DVS bucks can be changed when enabled".
In case the regulator is already set to specified voltage, do nothing
instead of failing outright.

When regulator consumer attempts to set enables regulator which cannot
be controlled because it is already always enabled, the driver aborts
with -EINVAL. Again, do nothing in such case and return 0, because the
request is really fulfilled, the regulator is enabled.

29d7153ec3 power: Rename CONFIG_POWER to CONFIG_POWER_LEGACY
This option is used in pre-driver model code and much of it has never
been converted to driver model.

We want to add a new option to enable power support, so we can use a
simple rule in the Makefile. Rename this one, which is really about
a particular implementation of power.

Also update the pmic.h header file so it either includes the legacy
API or the driver model one.

power/regulator will not be built if just CONFIG_SPL_DM_REGULATOR is

For example, if we just need a GPIO regulator in SPL:
CONFIG_DM_REGULATOR=y
CONFIG_SPL_DM_REGULATOR=y
CONFIG_DM_REGULATOR_GPIO=y
CONFIG_SPL_DM_REGULATOR_GPIO=y

Will not suffice, since the entire regulator build for SPL depends on

e3e2470fdd drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

8b8c99bd3e power: regulator: stm32: vrefbuf: fix a possible overshoot when re-enabling
There maybe an overshoot:
- when disabling, then re-enabling vrefbuf too quickly
- or upon platform reset as external capacitor maybe slow
  discharging (VREFBUF is HiZ at reset by default).
VREFBUF is used by ADC/DAC on some boards. An overshoot on the reference
voltage make the conversions inaccurate for a short period of time. So:
- Don't put the VREFBUF in HiZ when disabling, to force an active
  discharge.
- Enforce a 1ms OFF/ON delay, also upon reset

Penalty is a 1ms delay is applied (even for a cold boot), when enabling
VREFBUF.

e88d6979d1 regulator: fix: enable gpio when requested
The fix in commit b7adcdd073 has the side-effect that the regulator
will be disabled when requesting the relevant gpio in
regulator_common_ofdata_to_platdata() and enabled in
regulator_pre_probe() when the regulator was already enabled.
This leads to a short interruption in the 3.3V power to the PCIe
slot on the firefly-rk3399 which makes an ADATA SX8000NP NVMe SSD
unhappy.

Fix this by setting the GPIOD_IS_OUT_ACTIVE flag again when the
'regulator-boot-on' property is set, but check for this property
explicitly instead of relying on the "boot_on" member of
the uclass platdata.

b7adcdd073 regulator: fix: Move code to enable gpio regulator to pre_probe from ofdata_to_platdata
The commit e8e9715df2 ("regulator: fixed: Modify enable-active-high behavior")
fixed the regulator driver behavior when 'enable-active-high' is defined.
Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member
to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator.

The issue here is that regulator_common_ofdata_to_platdata() is called
_before_ regulator_pre_probe() function in which the 'regulator-boot-on'
property is asserted.

As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name()
called in the former function is not enabling the regulator.
This is problematic for e.g. i.MX ethernet driver, which then tries to
perform initialization without power (and fails).

The solution here is to explicitly enable regulator in regulator_pre_probe()
callback only when 'regulator-boot-on' property is present in device tree.
The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is
requested.
