Both advertiser and scanner demonstrate the use of extended advertising
and scanning, and how to gracefully restart the extended advertisements
through the use of recycle() callback. In the sample, the advertiser
initiates a connectable advertisement set, which prompts the scanner to
connect. After the connection is established, the advertiser waits for
5 seconds to disconnect. After the connection is dropped, the advertiser
immediately restarts broadcasting, while the scanner cools-down for
5 seconds to restart its process.

Where extended advertising is restablished through the use of

Added on the bt_conn_cb set, used to notify listeners that a previously
allocated connection object has been freed. Used for e.g: restart
extended advertisements.

- Which allow listeners to attempt to use the freed connection object to
perform actions as e.g: start connectable advertisements.
- Refactored bt_conn_unref() so it does not access conn struct after
decrementing its reference count.

Allow to use H7 SPI FIFO to improve performance.
SPI FIFO usage can be enabled/disabled from devicetree.
Signed-off-by: Daniel Gaston Ochoa <dgastonochoa@gmail.com>
Set the transfer size in SPI H7 and check EOT instead of TXC
to be sure the transaction has finished. This is required to
enable the use of the SPI FIFO, as otherwise SPI seems to
operate in "continuous mode", which produces several SCK cycles
after the last frame has been sent/received. More details in the PR.

The sample illustrates how to calculate feedback value based on I2S
sample clock measurement or indirect I2S FRAMESTART and USBD SOF.
The sample is currently only supported on nrf5340dk_nrf5340_cpuapp
target because the feedback measurement uses target specific
peripherals.
While it should be possible to perform feedback value calculation
entirely in software (possibly with some additional filtering due
to software scheduling jitter), the I2S API does not provide necessary
timestamps.

Introduce new USB Audio 2 implementation written from scratch. Main goal
behind new implementation was to perform entity configuration with
devicetree bindings, hiding the descriptor complexity from application.
Initial implementation is working at Full-Speed only. High-Speed support
will come later, but even at Full-Speed only this is viable replacement
for old stack USB Audio 1 class (USB Audio 1 is limited to Full-Speed by
specification, i.e. it is explicitly forbidden for USB Audio 1 device to
work at High-Speed).
Implemented is only absolute minimum set of features required for basic
implicit and explicit feedback samples. Only one sample frequency is
currently supported. Optional interrupt notifications are not supported.

Extend macros from creating a PM device with an optional argument
which indicate whether type of device is ISR_SAFE or not.
Signed-off-by: Krzysztof Chruściński <krzysztof.chruscinski@nordicsemi.no>
In many cases suspending or resuming of a device is limited to
just a few register writes. Current solution assumes that those
operations may be blocking, asynchronous and take a lot of time.
Due to this assumption runtime PM API cannot be effectively used
from the interrupt context. Zephyr has few driver APIs which
can be used from an interrupt context and now use of runtime PM
is limited in those cases.
Patch introduces a new type of PM device - synchronous PM. If
device is specified as capable of synchronous PM operations then
device runtime getting and putting is executed in the critical
section. In that case, runtime API can be used from an interrupt
context. Additionally, this approach reduces RAM needed for
PM device (104 -> 20 bytes of RAM on ARM Cortex-M).

usbh_req_desc() truncates the descriptor id. This problem is most

This commit introduces <type>_VERSION_TWEAK_STRING which includes
the tweak field in the string, but without the extra version.
This format is used by MCUboot / imgtool, and thus makes it easier to
align code to the format used by MCUboot.
This commit also introduces <type>_VERSION_EXTENDED_STRING which
includes the tweak field in the string in addition to the extra version
field.
