480a8ad683 mfd: adp5585: Add Analog Devices ADP5585 core support
The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the chip by modelling it as an MFD device, with two
child devices for the GPIO and PWM functions.

The driver is derived from an initial implementation from NXP, available
in commit 8059835bee19 ("MLK-25917-1 mfd: adp5585: add ADI adp5585 core
support") in their BSP kernel tree. It has been extensively rewritten.

Marvell 88PM886 is a PMIC which provides various functions such as
onkey, battery, charger and regulators. It is found for instance in the
samsung,coreprimevelte smartphone with which this was tested. Implement
basic support to allow for the use of regulators and onkey.

288b550463 mfd: pm8008: Rework to match new DT binding
Rework the pm8008 driver to match the new devicetree binding which no
longer describes internal details like interrupts and register offsets
(including which of the two consecutive I2C addresses the registers
belong to).

Instead make the interrupt controller implementation internal and pass
interrupts to the subdrivers using MFD cell resources.

Note that subdrivers may either get their resources, like register block
offsets, from the parent MFD or this can be included in the subdrivers
directly.

In the current implementation, the temperature alarm driver is generic
enough to just get its base address and alarm interrupt from the parent
driver, which already uses this information to implement the interrupt
controller.

The regulator driver, however, needs additional information like parent
supplies and regulator characteristics so in that case it is easier to
just augment its table with the regulator register base addresses.

Similarly, the current GPIO driver already holds the number of pins and
that lookup table can therefore also be extended with register offsets.

Note that subdrivers can now access the two regmaps by name, even if the
primary regmap is registered last so that it is returned by default when
no name is provided in lookups.

Finally, note that the temperature alarm and GPIO subdrivers need some
minor rework before they can be used with non-SPMI devices like the
PM8008. The temperature alarm MFD cell name specifically uses a "qpnp"
rather than "spmi" prefix to prevent binding until the driver has been
updated.

0742c2a633 mfd: max597x: Add support for MAX5970 and MAX5978
Implement a regulator driver with IRQ support for fault management.
Written against documentation [1] and [2] and tested on real hardware.

Every channel has it's own regulator supply nammed 'vss1-supply' and
'vss2-supply'. The regulator supply is used to determine the output
voltage, as the smart switch provides no output regulation.
The driver requires the 'shunt-resistor-micro-ohms' to be present in
the devicetree to properly calculate current related values.

You must specify compatible devictree layout:

regulator@3a {
        reg = <0x3a>;
        vss1-supply = <&p3v3>;
        compatible = "maxim,max5978";

        ...

        regulators {
                sw0_ref: SW0 {
                        regulator-compatible = "SW0";
                        shunt-resistor-micro-ohms = <12000>;

869b9eddf0 mfd: intel-m10-bmc: Add PMCI driver
Add the mfd driver for the Platform Management Component Interface
(PMCI) based interface of Intel MAX10 BMC controller.

PMCI is a software-visible interface, connected to card BMC which
provided the basic functionality of read/write BMC register. The access
to the register is done indirectly via a hardware controller/bridge
that handles read/write/clear commands and acknowledgments for the
commands.

Previously, intel-m10-bmc provided sysfs under
/sys/bus/spi/devices/... which is generalized in this change because
not all MAX10 BMC appear under SPI anymore.

96836a35ff mfd: Drop obsolete dependencies on COMPILE_TEST
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

The TPS65219 is a power management IC PMIC designed to supply a wide
range of SoCs in both portable and stationary applications. Any SoC can
control TPS65219 over a standard I2C interface.

It contains the following components:
- Regulators.
- Over Temperature warning and Shut down.
- GPIOs
- Multi Function Pins (MFP)
- power-button

This patch adds support for tps65219 PMIC. At this time only
the functionalities listed below are made available:

- Regulators probe and functionalities
- warm and cold reset support
- SW shutdown support
- Regulator warnings via IRQs
- Power-button via IRQ

Linus expressed a desire to have intel_soc_pmic_crc.o (INTEL_SOC_PMIC,

I2C_DESIGNWARE_PLATFORM=m, to enhance build test coverage.

The PMIC driver won't work in this case since it requires
I2C_DESIGNWARE_PLATFORM=y to operate properly, but adding
"|| COMPILE_TEST" does improve the build test coverage.

5e88619b30 mfd: silergy,sy7636a: Add config option MFD_SY7636A
Add a specific MFD_SY7636A config option.

As part of this change we can use MFD_SY7636A as a dependency for all
SY7636a components and also remove the name from MFD_SIMPLE_MFD_I2C as
it no longer needs to be selectable.
