The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.

This converts the STMPE MFD device tree bindings to the YAML
schema.

Reference the existing schema for the ADC, just define the
other subnode schemas directly in the MFD schema.

Add two examples so we have examples covering both the simple
GPIO expander and the more complex with ADC and touchscreen.

Some in-tree users do not follow the naming conventions for nodes
so these DTS files need to be augmented to use proper node names
like "adc", "pwm", "gpio", "keyboard-controller" etc before the
bindings take effect on them.

Immutable branch between MFD, Pinctrl and soundwire due for the v6.6 merge window

Immutable branch between MFD and Regulator due for the v6.6 merge window

This commit prepares a following commit for the regulator part of the MFD.
The driver should support different device chips that differ in their
register definitions, for instance to control LDOA1 and SWB2.
So it is necessary to use a dedicated regulator description for a
specific device variant. Thus, the content from DEVICEID Register 1 is
used to choose a dedicated configuration between the different device
variants.

Currently the in-band alerts for SoundWire peripherals can only
be communicated to the driver through the interrupt_callback
function. This however is slightly inconvenient for devices that wish
to share IRQ handling code between SoundWire and I2C/SPI, the later
would normally register an IRQ handler with the IRQ subsystem. However
there is no reason the SoundWire in-band IRQs can not also be
communicated as an actual IRQ to the driver.

Add support for SoundWire peripherals to register a normal IRQ
handler to receive SoundWire in-band alerts, allowing code to be
shared across control buses. Note that we allow users to use both the
interrupt_callback and the IRQ handler, this is useful for devices
which must clear additional chip specific SoundWire registers that are
not a part of the normal IRQ flow, or the SoundWire specification.

We just sorted the entries and fields last release, so just out of a
perverse sense of curiosity, I decided to see if we can keep things
ordered for even just one release.

The answer is "No. No we cannot".

I suggest that all kernel developers will need weekly training sessions,
involving a lot of Big Bird and Sesame Street.  And at the yearly
maintainer summit, we will all sing the alphabet song together.

I doubt I will keep doing this.  At some point "perverse sense of
curiosity" turns into just a cold dark place filled with sadness and
despair.
