Add a generic software PWM driver as a fallback
when no dedicated hardware PWM pins are available.
This implementation leverages a single hardware
timer interrupt as a time base to derive an
arbitrary number of software-controlled PWM channels.
The period is the same for all channels.
This enables use of LED brightness and blink APIs.
Tested on Nucleo H563ZI with this overlay:
/ {
status_leds: status_leds {
compatible = "pwm-leds";
status_led_1: status_led_1 {
pwms = <&soft_pwm 0 PWM_MSEC(10) PWM_POLARITY_NORMAL>;
label = "1";
};
};
soft_pwm: soft_pwm {
compatible = "zephyr,pwm-bitbang";
#pwm-cells = <3>;
timer = <&tim6_counter>;
pwm-gpios = <&gpiob 0 GPIO_ACTIVE_HIGH>;
};
};
&timers6 {
status = "okay";
st,prescaler = <24999>;
tim6_counter: counter {
status = "okay";
};
};

Add a comprehensive driver for the Microchip PAC194x/195x family of
multi-channel power monitors. This driver supports VBUS, VSENSE,
and power accumulation measurements.
Key features and implementation details:
- Support for PAC1941/42/43/44 (9V FSR) and PAC1951/52/53/54 (32V FSR).
- Efficient I2C handling: uses per-channel burst reads to optimize
bus bandwidth based on enabled channels.
- Flexible Refresh Modes: introduced SENSOR_ATTR_REFRESH_MODE to
allow users to choose between AUTO_WAIT (synchronous),
AUTO_NOWAIT (asynchronous/latched), and MANUAL modes.
- Broadcast Support: added a force refresh command using I2C
General Call (0x00) to synchronize snapshots across multiple
sensors (up to 16 instances) simultaneously.
- Configurable range: support for Unipolar, Bipolar, and Bipolar
Half FSR modes via Devicetree.
Tested on RISC-V (ESP32-C3) with 16 PAC1944 instances.

Combine the Cortex-M7 ENET workaround updates into one commit.
- clear CACHE_ENET on i.MX RT11xx Cortex-M7 for ERR050396
- disable ETH_NXP_ENET_USE_DTCM_FOR_DMA_BUFFER by default on Cortex-M7
- keep the final Kconfig condition independent of
DT_HAS_NXP_ENET1G_ENABLED
This avoids touching the same Kconfig and SoC files in follow-up
commits while preserving the intended behavior for PR #106679.
Validation:
- branch history squashed so workaround files are updated once
in the series

The PDL bundles completion (RD_CMPLT/WR_CMPLT) and ERR events into
a single cbEvents() call. The handler gave transfer_sem twice, leaking
count to the next transfer on i2c_scan.
Make the error and completion paths mutually exclusive with else-if
so exactly one k_sem_give() occurs per callback.

On STM32H5 / STM32U5 with GPDMA the USART can stop generating DMA RX
requests after uart_rx_disable() clears DMAR and DMAR is later re-enabled.
Toggling the USART enable (UE) before re-asserting DMAR resets the USART
internal state machine and allows RX DMA requests to resume.

The `pinctrl_soc_pin_t` format occupied two uint32_t even though all info
it stores can be compressed in 32 bits only, and also didn't map very well
to the hardware (especially on STM32F1). Due to defects, the format was
also NOT what the `stm32_gpioport_configure_pin()` function consumed to
actually configure a GPIO port, requiring additional decoding/manipulation
logic.
Introduce a vastly reworked format which only requires 32-bit per pinctrl
entry and maps nicely to hardware and becomes the new format consumed by
stm32_gpioport_configure_pin(). This heavily simplifies the pinctrl driver
since it no longer needs to examine the actual values (except to determine
the target GPIO port and pin - this is done on purpose!). The GPIO driver
converts Zephyr flags to this new format too.

Simplify the logic translating Zephyr GPIO flags into STM32-specific flags:
- flatten if chain for output type determination
- change how input modes are handled
- introduce new INPUT_FLOAT/INPUT_PUPD pincfg values which are used for
input mode depending on whether or not user requests pull-up/down
- these values can have the PULL_UP / PULL_DOWN OR'ed into them
- share PU/PD decoding between INPUT and OUTPUT mode
While at it, also return -ENOTSUP to caller if attempting to set a pull-up
or pull-down on a disabled pin instead of silently discarding the request.

Move the logic which sets the output level based on configuration to the
common `stm32_gpioport_configure_pin()` function to reduce duplication.
To support the GPIO use case where a pin's configuration is changed without
modifying its output state, a new parameter is introduced which specifies
whether or not the output level should be modified.

Use `_Pos`/`_Msk` suffixed defines for pinctrl format bits definitions and
