Maureen Helm a9b223b26b drivers: sensor: Refactor drivers to use SENSOR_DEVICE_DT_INST_DEFINE
Refactors all sensor drivers to use SENSOR_DEVICE_DT_INST_DEFINE, which
is a sensor-specific variant of DEVICE_DT_INST_DEFINE that provides a
common place to instantiate additional data structures for the future
sensor subsystem and/or sensor driver stats.

This approach was inspired by I2C_DEVICE_DT_INST_DEFINE to streamline
adding I2C stats support across all I2C drivers.

Kumar Gala 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

Martí Bolívar 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.

James Harris 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.

Andy Ross 32bb2395c2 timeout: Fix up API usage
Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them.  Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:

+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
  values for equality (e.g. with K_FOREVER or K_NO_WAIT).

+ Adding a k_msleep() synonym for k_sleep() which can continue to take
  integral arguments as k_sleep() moves away to timeout arguments.

+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
  generate timeout arguments.

+ Removing the usage of K_NO_WAIT as the final argument to
  K_THREAD_DEFINE().  This is just a count of milliseconds and we need
  to use a zero.

This patch include no logic changes and should not affect generated
code at all.

Ulf Magnusson 677f1e6db9 kconfig: Turn pointless/confusing 'menuconfig's into 'config's
Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.

Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.

    [*] Enable foo ---

This is how it would be shown if there were children but they all
happened to be invisible as well.

With a regular 'config', it turns into

    [*] Enable foo

Change all pointless 'menuconfig's to 'config's.

See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.
