Configure the reference buffers when using external reference voltage for a
channel. For the internal reference the datasheet[1] recommends that the
buffers are disabled and for external references they should be disabled if
REFPx/REFNx is close to AVDD/AVSS. After reset the positive reference
buffer is enabled and the negative is disabled. The default values
correspond to the example circuit for a two-wire and four-wire PT100 RTD
measurement with low-side reference.[2][3]
The values configured by the driver are maybe a little opinionated, but the
current behaviour is kept to avoid surprises for people that are happy with
the drivers defaults.
The change applies to both ads11xs0x and ads124xs0x series.

Add support for PWM input capture functionality to the NXP MCUX PWM
driver. This enables measurement of pulse width and period of external
PWM signals.
Key features added:
- PWM capture configuration and control APIs
- Interrupt-driven capture with overflow handling
- Support for both pulse width and period measurement
- Configurable input filtering
- Support for continuous and one-shot capture modes
The implementation uses FlexPWM channel X as the dedicated input
capture channel, while channels 0 and 1 remain available for PWM
output. Capture functionality is conditionally compiled based on
CONFIG_PWM_CAPTURE configuration option.

In PWM_SetupPwm implementation, there is a check:
temp = pwmClock / pwmFreq_Hz;
assert(temp <= 0xFFFFU);
Currently pwmFreq_Hz is 1, makes assert failed with
high frequency pwmClock. Since VALx values is set
directly for edge aligned PWM, the pwmFreq_Hz here is
a dummy value, set pwmFreq_Hz equal to pwmClock
frequency to pass assert check.

If CONFIG_SDMMC_STM32_CLOCK_CHECK=y but the SDMMC node lacked domain clock,

A set of preliminary (but harmless) changes to prepare for adding the HAL

- Rename CMake variables for clarity and consistency, adding an 'LBM_LIB_'
prefix when the path is a library / module path.
- Change zephyr_library_include_directories to zephyr_include_directories
for the RAL/RALF includes, since these headers may be needed outside the
library itself.
- Make lbm_common.h available to code outside the driver directory.

Add proper support for the 1-bit CAN protocol engine clock multiplexer
present in some NXP FlexCAN instances.
Both possible input clocks are now represented as named clocks in the

property "clk-source" now selects the correct clock in addition to setting
the multiplexer bit (CLKSRC) in the FlexCAN CTRL1 register.

So far using recvfrom() and send() from two different threads was not
possible, since thread attempting send() was blocked by the thread
executing recvfrom(). All other APIs were also blocking each other, while
it was not necessary. One example use case in Zephyr tree is MCUMGR SMP
over UDP implementation, which resuled in communication timeouts.
Release socket lock while actively polling, so other APIs executed from
other threads can safely progress. Do this using k_condvar_wait() API with
socket mutex, so that mutex is safely released and reaquired during wait.

When ESP32 operates in AP-only mode the network interface is
initialized with the STA MAC address, but the Wi-Fi hardware operates
with the AP MAC address (typically STA MAC + 1).
Some Wi-Fi clients correctly address frames to the AP MAC, causing them
to be dropped by the ethernet L2 layer with "Dropping frame, not for me"
because the interface link address doesn't match.
Fix this by updating the interface link address to the AP MAC when
enabling AP mode, and restoring the STA MAC when disabling AP mode.
