In order to have the possibility to configure the regulators at system
startup through DM support, all LDOs and bucks must be able to be
changeable. Currently there is a limitation to change the values when
the output is enabled. Since the driver is based on the ROHM BD71837 and a
comment that describes a limitation about switching while the output is
enabled can also be found there, the limitation probably comes from this type.

Tighten up symbol dependencies in a number of places. Ensure that a SPL
specific option has at least a direct dependency on SPL. In places
where it's clear that we depend on something more specific, use that
dependency instead. This means in a very small number of places we can
drop redundant dependencies.

Changes SCMI driver API function devm_scmi_process_msg() to add
an SCMI channel reference argument for when SCMI agent supports
SCMI protocol specific channels. First argument of devm_scmi_process_msg()
is also change to point to the caller SCMI protocol device rather
than its parent device (the SCMI agent device).
The argument is a pointer to opaque struct scmi_channel known from
the SCMI transport drivers. It is currently unused and caller a pass
NULL value. A later change will enable such support once SCMI protocol
drivers have means to get the channel reference during initialization.

Changes devm_scmi_process_msg() first argument from target parent device
to current SCMI device and lookup the SCMI agent device among SCMI device
parents for find the SCMI agent operator needed for communication with
the firmware.
This change is needed in order to support CCF in clk_scmi driver unless
what CCF will fail to find the right udevice related to exposed SCMI
clocks.
This patch allows to simplify the caller sequence, using SCMI device
reference as parameter instead of knowing SCMI uclass topology. This
change also adds some protection in case devm_scmi_process_msg() API
function is called for an invalid device type.

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.

This option is used in pre-driver model code and much of it has never

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

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

power/regulator will not be built if just CONFIG_SPL_DM_REGULATOR is
enabled. It needs CONFIG_SPL_POWER_SUPPORT to be enabled as well.
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
CONFIG_SPL_POWER_SUPPORT. Elaborate that information in the Kconfig
dependency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

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.

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.

The fix in commit b7adcdd073c0 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.

ofdata_to_platdata
The commit e8e9715df2d4 ("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.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.
