df81fef944 drivers: sensor: Convert Kconfig bus 'depends on' to 'select'
This change in pattern is meant to address a misconfiguration issue
that can occur for sensors that support being on multiple busses
like I2C & SPI.

For example, you can have a configuration in which such a sensor is
on the I2C bus in the devicetree and the sensor is enabled.  However
the application configuration enables CONFIG_SPI=y and CONFIG_I2C=n
and this will cause the sensor driver to be built by default, however
since we don't have the I2C bus enabled the driver will not compile
correctly.

Previously we had been adding to board Kconfig.defconfig something
like:

	config I2C
		default y if SENSOR

This pattern doesn't scale well and may differ from what an application
specific need/use is.

So instead move to a pattern in which we leave the default enablement
up to the devicetree "status" property for the sensor.  We then have
the Kconfig move from 'depends on <BUS>' to 'select <BUS>' and in
the case of drivers that support multiple busses we have the Kconfig
be: 'select <BUS> if $(dt_compat_on_bus,$(<DT_COMPAT>),<BUS>) for
each bus type the sensor supports.

This removes the need to add Kconfig logic to each board and enables
the bus subsystem and bus controller driver if the sensor requires
it by default in the build system.

Fixes: #48518

b789c11775 drivers: sensor: Change fxos8700 default mode from accel-only to hybrid
The fxos8700 device supports 3 modes: accelerometer-only,
magnetometer-only, or hybrid (accelerometer and magnetometer) modes. The
accelerometer-only mode is register compatible with mma8451q, mma8652fc,
and mma8653fc, which allows the fxos8700 driver to be used with these
devices as well.

Most in-tree boards can use hybrid mode because they have the fxos8700
device, therefore we change the driver default to match the common case.
For the handful of boards that have an mma86xx or mma84xx device, we
override the driver default to accelerometer-only mode. As a result, we
can enable the magn_polling sample application for the fxos8700 driver
without having to add a bunch of board-specific configuration overlays
for hybrid mode.

bd8afe9365 drivers: sensor: clean up zephyr_library calls
In drivers/sensor/CMakeLists.txt, we have various lines like this:

    add_subdirectory_ifdef(CONFIG_FOO foo)

Then drivers/sensor/foo/CMakeLists.txt says:

    zephyr_library()
    zephyr_library_sources_ifdef(CONFIG_FOO foo.c)

This is redundant; the foo/CMakeLists.txt won't be added to the build
system unless CONFIG_FOO=y in the first place, so there's no need for
extra boilerplate testing it again.

Remove all these unnecessary instances in each sensor driver's
CMakeLists.txt using this pattern:

    zephyr_library()
    zephyr_library_sources(foo.c)

In a couple of places, the '.c' extension is missing. Add them in for
consistency when that happens.

b10428163a kernel: sem: add K_SEM_MAX_LIMIT
Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".

Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.

In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.

These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

The magnetometer vector-magnitude function will generate an interrupt
when magnitude is greater than specified threshold value. The user
may program the threshold value to establish the conditions needed
to detect a magnetic vector-magnitude change event. Depending on the
values chosen for the reference values, this function may be
configured to detect a magnetic field magnitude that is above
a preset threshold (with reference values = 0), or a change in magnitude
between two magnetic vectors greater than the preset threshold
(with reference values non-zero).

Default configuration of M_VECM_CFG register (address 0x69) is 0x4e.

eddd98f811 kconfig: Replace some single-symbol 'if's with 'depends on'
I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.

There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.

The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).

Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.

Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.

Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.

The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.

(Everything above is true for choices, menus, and comments as well.)

Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.
