This renames MIN_DELAY to HPET_CMP_MIN_DELAY, and also allows it
to be overridden. The default delay is for HPET with relative
high frequency, and may not suitable for all HPET
implementations.

This patch states that the Everlight B1414 LED controller is compatible
with the Worldsemi WS2812. Some information about it is added to the
WS2812 DT binding and driver Kconfig files.

Since this driver is working reliably, let's use k_usleep() instead of
k_busy_wait() (as suggested in a TODO comment) to latch and reset the
LED strip controller.

Some devices compatibles with the WS2812 IC have a different reset/latch
delay.
This patch introduces the "reset-delay" optional property for the WS2812
DT binding and adds support to the ws2812_spi driver. This new property
allows to configure the reset/latch delay of a WS2812 compatible LED
strip controller from its DT node.
If omitted the driver uses 8 microseconds by default (which is good for
the WS2812 IC).

Some devices compatibles with the WS2812 IC have a different channel to
color mappings (e.g. RGB, BGR, RGBW, etc).
This patch introduces the "color-mapping" required property for the
WS2812 DT binding and adds support to the ws2812_gpio and ws2812_spi
drivers. This new property allows to configure the color to channel
mapping of a WS2812 compatible LED strip controller from its DT node.
Since this property also allows to know if a white channel is available,
then this patch removes the "has-white-channel" property.

When DMA switches from one buffer to another ENDRX followed by
RXSTARTED is generated. Code flow assumes that ENDRX will be
handled before RXSTARTED but this may not be the case if there
is a short between ENDRX and RXSTARTED and event occurs after
ENDRX event check but before RXSTARTED event check. In that case,
RXSTARTED event is handled first. Such case may happen if there
is a higher priority interrupt that may preempt UARTE interrupt
handler.

RTC interrupt was reading CC value and passing it to the handler.
However, higher priority interrupt could preempt RTC interrupt
and set new CC value. In that case CC value read in the RTC
interrupt context was not the one that triggered the interrupt.
Added fallback to COUNTER value if that case is detected.
Using COUNTER is not as precise as CC because it returns time
when event was handled and not when event occured but it is the
only option since CC value is overwritten.

A syscon device is a device managing a memory region containing a set of

of device. We need a driver for that because several other drivers could
use the same region at the same time and we need to io-map the region at
boot for MMU enabled platforms.

Move GPIO devices clock handling in stm32_pin_configure function
which is also used in stm32_setup_pins.
Additionally, add device usability check to be sure gpio driver
was initialized before being used by pinmux pseudo driver.
Last, going from the assumption that GPIO devices should be
initialized before being used by pinmux, then there is no need
to enable clock in case CONFIG_PM_DEVICE_RUNTIME=n.

This adds support for controlling the SUBGHZSPI NSS line in STM32WL
devices. This is a special dedicated SPI port only connected to the
radio device internally, chip select happens through a bit in the PWR
module. Adding a special dt-property to identify the port, it all gets
built out on non-WL devices.
Deduplicate the existing dts bindings in the process, and add the new
one for the special spi with the new property.

CRC16 was removed by simply decreasing length of the last fragment by 2.
This worked as long as last fragment was longer than 1 byte. If not,
then last fragment was corrupted (its length ended up being 65535),
leading to undefined behavior.
Fix CRC16 removal by utilizing recently introduced
net_pkt_remove_tail(), that properly handles multiple fragments.
