The nRF91 Serial Modem application restarts the PPP automatically,
which breaks our re-dialing attempts if network already recovered.
Instead, request to CFUN=4 and PPP to stop, so that rest of dial
script can assume correct ordering of events.
The sequence of
AT#XPPP=1
AT+CFUN=1
AT#XCMUX=2
is very timing sensitive, as the last command switches CMUX channels,
but cannot anymore do it if PPP already started on DLC channel 2.
This is a bad design of AT#XPPP command which we workaround.

If we stay in DORMANT state long enough, the CMUX channel might enter
power saving mode which will then block URC messages unless we deal
with RING event.
Also, change RING log level to DBG. It is too verbose otherwise.

If we receive PPP_DEAD event before receiving the DEREGISTERED, we
could directly try to recover connection without waiting in the
dormant state.
If we would stay in the DORMANT state, the PPP_DEAD event is not
going to happen againt, and it would deadblock.
Depends on the modem, which is received first.
There is no guarantee of ordering.

When packet domain events are requested with AT+CGEREP=1 we receive
these +CGEV events that indicate the state of data connection.
This might not always be the same as being "registered".
The information could also be used if we want to use the default CID

Configure all nRF70 GPIO pins (BUCKEN, VDDIO_CTRL, SR RF switch) to
OUTPUT_INACTIVE state during driver initialization to prevent floating
pins from accidentally powering the module or affecting RF switch
before the interface is brought up.
This addresses an issue where GPIO configuration was delayed until
the interface was brought up for the first time, leaving voltage control
pins floating which could result in unintended power supply.
Fixes#100993.

Make cc13xx_cc26xx_irq_tx_ready check that the TX Ready interrupt
occurred, instead of checking whether there is some free space in
the UART TX FIFO. This prevents a race condition from occurring in
OpenThread Spinel protocol implementation, when a UART RX interrupt
is received right after otPlatUartSend was called, between the
assignement of 1 to ot_uart.tx_busy and the initialization of

Fix race condition between DMA ISR and work queue that caused RX
length underflow when calculating len = counter - offset.
Both mcux_lpuart_async_rx_timeout (work queue) and dma_callback
(ISR) modified rx_dma_params without locking, causing the ISR to
update counter/offset mid-calculation, resulting in integer
underflow and system crash.
Solution: Add irq_lock() protection around all rx_dma_params
accesses in async_evt_rx_rdy(), mcux_lpuart_async_rx_flush(),
and async_evt_rx_buf_release().

Split error handling in mcux_lpuart_rx_enable() to distinguish
between DMA status query failures (error) and busy status (debug).
- Use LOG_ERR for get_status failures with specific error code
- Use LOG_DBG for busy status (expected condition, valid -EBUSY)
- Improves debuggability by providing clearer diagnostic messages

When an async transfer finished quickly, the internal state of
the driver could come out of sync with the hardware. The tx/rx
enabled flag and PM lock was taken after starting the DMA
transaction, which caused issues if the DMA complete callback
was called before the flags were updated. Set the flag and take
the PM lock prior to starting the DMA transaction to avoid this.
Also release the PM rx lock upon successful completion of a
transfer. The lock was previously only released when the user
manually called `uart_rx_disable()`.

PLL mode on MSIK/MSIS should be enabled only if property `msi-pll-mode` is
present on the generator's DT node. However, the STM32U3 clock driver did
not check this property and unconditionally enabled PLL mode. This is an
issue because PLL mode requires an LSE generator to be provided, which was
asserted at build time, preventing usage of MSIS/MSIK without an LSE even
if the target application did not need the accuracy provided by PLL mode.
Fix by enabling PLL mode for each MSIx generator only if the `msi-pll-mode`
property is enabled on the corresponding DT node.

The UARTE instance must be disabled before the pinctrl state is
updated like it is done other places in this driver.
While the uarte is enabled, it controls the pins, keeping TX high
for example. Trying to apply pinctrl will have no effect other
than enabling pin retention, so the TX pin which should now be low
and configured as disconnected input, stays an output driven high.
Issue was discovered as the suspended UARTE was backpowering
devices connected to it because of the driven output pins.

This change updates uart_stm32_dma_rx_flush() to detect the wrap case
and emit two contiguous UART_RX_RDY events in order:
- tail: [offset .. buffer_length)
- head: [0 .. counter)
This guarantees that each RX_RDY event satisfies offset + len <=
buffer_length.
Non-cyclic behavior and cyclic non-wrapping cases remain
unchanged.

The work-queue based timing source ignored the interval passed via
.update() and always scheduled using the configured microstep interval.
In single-edge mode the step/dir driver programs the timing source with
half the microstep period to generate the required high/low edges, so
ignoring .update() causes the step toggling rate to be wrong.
Store the timing-source interval on update and schedule work using that
value.
