("drivers: entropy: Add entropy driver for MCUX CAAM")
added a shim entropy driver whose initialization function
always returns 0, even when the underlying HAL API fails.
This is wrong; if the device initialization function fails, it must
return nonzero by contract. Papering this over with an assert is not
enough. Fix it by returning -ENODEV on error.

The sleep pin is optional and the driver checks for availability during
runtime. Currently the logic is inverted and therefore the driver exits
early if the pin is actually available. This pr fixes this behavior.
Also: Add `fallthrough` flags to switch/case

This commit is converting the DMA kconfig for the stm32 dma driver
with new macro DT_HAS_<COMPAT>_ENABLED.
Signed-off-by: Francois Ramu <francois.ramu@st.com>
It includes the definition for the DMA peripheral of this type,
present on stm32U5 devices.
A particular DMA_STM32U5 config is selected for that purpose.
The driver is derived from the existing dma_stm32.c
The GPDMA is counting channels (0-15) ; stream offset is 0.

Adding I2C FIFO mode can reduce the time between each byte to
improve the I2C bus clock stretching during I2C transaction.
The I2C master supports two 32-bytes FIFOs, channel A and C
are supported now.
I2C FIFO mode of it8xxx2 can support I2C APIs including:
i2c_write(), i2c_read(), i2c_burst_read.
Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
0.52ms(2.4ms->1.88ms) compared to the original pio mode when the
frequency is 100KHz.
3. It is normal to read sensor data through I2C on Nereid's platform.

When a cache API function is called from userspace, this results on
ARM64 in an OOPS (bad syscall error). This is due to at least two
different factors:
- the location of the cache handlers is preventing the linker to
actually find the handlers
- specifically for ARM64 and ARC some cache handling functions are not
implemented (when userspace is not used the compiler simply optimizes
out these calls)
Fix the problem by:
- moving the userspace cache handlers to a their logical and proper
location (in the drivers directory)
- adding the missing handlers for ARM64 and ARC

This is a follow-up to commit fd07675574.
The above commit was supposed to introduce overriding of the S0S1
drive setting with S0D1 for TWI/TWIM peripherals, but since it did
not properly update the `nrf_pin_configure()` function (the `drive`
parameter was only added in the function signature, but then it was
not used...), the drive setting was in fact not overridden.
This commit corrects this embarrassing oversight.

The driver is writing the DTS nist-config to the RNG periph.
following the validation sequence described by the RefMan.
It depends on the he RNG IP version and is present on some
mcu devices : all with CONDRST bit.
Depends on the RNG CR Autoreset.

For the stm32 mcu with a CONDRST bit in its RNG_CR
for conditioning Soft Reset, the driver must wait for
the bit to be 0 after disabling. This could take
about 2 AHB clock cycles + 2RNG clock cycles.

It is frequent to find variable definitions like this:
```c

```
That is, module level variables that are statically initialized with a

the variable can also be declared as const (immutable). This patch
constifies all such cases.

This is a follow-up to commit e1c0a494b3.
The `tca954x_transfer()` function cannot call `i2c_transfer_dt()`,

itself. Hence, this commit restores the call to `i2c_transfer()`.
