7ef2744e2f drivers: i2c: i2c_mcux_lpi2c: fix base address declarations
With commit 734adf52c6, the MCUX LPI2C config structure no longer
contains a direct base address pointer. The base address must be
accessed via DEVICE_MMIO_NAMED_GET. Some declarations in the LPCI2C
target mode handler still used the old method of accessing the base
address, causing a build failure. Fix these accesses to use the local
declaration of the "base" variable.

7b1349cfe6 stats: i2c: I2C stats
Adds the ability for I2C drivers to report synchronous transfer stats
using a I2C specific macro to define the device instance.

The macro creates a container for device_state which allows for per
instance device class common data structure to be used in the device
class api (ex: i2c.h). This is used to maintain per driver instance
stats for all i2c drivers. This is a reusable idea across other device
classes as desired.

Using Kconfig device class stats may be turned on/off individually
this way as well, in this case I2C_STATS.

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.

4dcfb5531c isr: Normalize usage of device instance through ISR
The goal of this patch is to replace the 'void *' parameter by 'struct
device *' if they use such variable or just 'const void *' on all
relevant ISRs

This will avoid not-so-nice const qualifier tweaks when device instances
will be constant.

Note that only the ISR passed to IRQ_CONNECT are of interest here.

7e0eed9235 devicetree: allow access to all nodes
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.

Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter
