The System Management Controller (SMC) on Apple Silicon machines is a
piece of hardware that exposes various functionalities such as
temperature sensors, voltage/power meters, shutdown/reboot handling,
GPIOs and more.
Communication happens via a shared mailbox using the RTKit protocol
which is also used for other co-processors. The SMC protocol then allows
reading and writing many different keys which implement the various
features. The MFD core device handles this protocol and exposes it
to the sub-devices.
Some of the sub-devices are potentially also useful on pre-M1 Apple
machines and support for SMCs on these machines can be added at a later
time.

connected via SPEEDY / ACPM rather than I2C, split out (move) all
I2C-specific driver code into its own kernel module, sec-i2c, and
make the existing sec-core module be just the transport-agnostic core

At the same time, update all defconfigs that reference the old kconfig

While at it, also update file header comments and module description(s)

The Maxim MAX77759 is a companion PMIC for USB Type-C applications and
includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C
Port Controller (TCPC), NVMEM, and a GPIO expander.
Fuel Gauge and TCPC have separate and independent I2C addresses,
register maps, and interrupt lines and are therefore excluded from the
MFD core device driver here.
The GPIO and NVMEM interfaces are accessed via specific commands to the
built-in microprocessor. This driver implements an API that client
drivers can use for accessing those.

These microcontroller units are used in network-attached-storage devices
made by QNAP and provide additional functionality to the system.
This adds the base driver that implements the serial protocol via
serdev and additionally hooks into the poweroff handlers to turn
off the parts of the system not supplied by the general PMIC.
Turning off (at least the TSx33 devices using Rockchip SoCs) consists of
two separate actions. Turning off the MCU alone does not turn off the main
SoC and turning off only the SoC/PMIC does not turn off the hard-drives.
Also if the MCU is not turned off, the system also won't start again until
it is unplugged from power.
So on shutdown the MCU needs to be turned off separately before the
main PMIC.
The protocol spoken by the MCU is sadly not documented, but was
obtained by listening to the chatter on the serial port, as thankfully
the "hal_app" program from QNAPs firmware allows triggering all/most
MCU actions from the command line.
The implementation of how to talk to the serial device got some
inspiration from the rave-sp servdev driver.

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.

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>;

...
regulators {

Four separate mfd drivers are in the "tmio" family, and all of
them were used in now-removed PXA machines (eseries, tosa, and
hx4700), so the mfd drivers and all its children can be removed
as well.

The cs5535-mfd driver uses CPU-specific data that is not available
for ARCH=um builds, so don't allow it to be built for UML.
Prevents these build errors:

The htc-pasic3 MFD device was only used in the PXA magician
machine that is now removed, so this can be recycled as well.

The ucb1400 MFD driver and its gpio and touchscreen child
drivers were only used on a few PXA machines that were unused
for a while and are now removed.
Removing these leaves the AC97 support as ALSA specific,
no other drivers are now connected through this interface.
