There's no need to list "tc3589x" in the DT match table. The I2C core
will strip any vendor prefix and match against the i2c_device_id table
which has an "tc3589x" entry.
Probably "tc3589x" and TC3589X_UNKNOWN could be removed altogether.
Use of that compatible was only on some STE platforms and was dropped
in 2013. There were ABI breaks in 2014 claiming no DTs in the wild. See
commit 1637d480f8 ("pinctrl: nomadik: force-convert to generic config
bindings").

There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it
turns out that the 2G version has a DMI product name of
"CHERRYVIEW D1 PLATFORM" where as the 4G version has
"CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are
unique enough that the product-name check is not necessary.
Drop the product-name check so that the existing DMI match for the 4G
RAM version also matches the 2G RAM version.

This pull request contains some cleanups to the core and some mostly
minor updates to a bunch of drivers and device tree bindings. One thing
worth pointing out is that it contains an immutable branch containing
support for a new mfd chip (Analog Devices ADP5585) with several sub
drivers. So expect to get the four affected commits also from my fellow
MFD and GPIO maintainers.

This is a platform/x86 library that is mostly being used by other
drivers not directly under arch/x86 anyway (with the exception of the
Intel MID setup code) so it makes sense that it lives under the
platform_data/x86/ directory instead.
No functional changes intended.

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.

of: remove internal arguments from of_property_for_each_u32()
dt-bindings: watchdog: add support for Amlogic A4 SoCs
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

The of_property_for_each_u32() macro needs five parameters, two of which
are primarily meant as internal variables for the macro itself (in the
for() clause). Yet these two parameters are used by a few drivers, and this
can be considered misuse or at least bad practice.
Now that the kernel uses C11 to build, these two parameters can be avoided
by declaring them internally, thus changing this pattern:
struct property *prop;
const __be32 *p;
u32 val;
of_property_for_each_u32(np, "xyz", prop, p, val) { ... }
to this:
u32 val;
of_property_for_each_u32(np, "xyz", val) { ... }
However two variables cannot be declared in the for clause even with C11,
so declare one struct that contain the two variables we actually need. As
the variables inside this struct are not meant to be used by users of this
macro, give the struct instance the noticeable name "_it" so it is visible
during code reviews, helping to avoid new code to use it directly.
Most usages are trivially converted as they do not use those two
parameters, as expected. The non-trivial cases are:
- drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway
- drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the
checks had to be replicated in a different way, making code more verbose
and somewhat uglier, but I refrained from a full rework to keep as much
of the original code untouched having no hardware to test my changes
All the changes have been build tested. The few for which I have the
hardware have been runtime-tested too.

Switch over to using software nodes/properties to describe the

allow to drop support for the platform data from TSC2007 driver
and rely solely on the generic driver properties.
Note: "model" is not part of defined device properties and is not
used by the TSC2007 driver, so it can be safely dropped.
