af77efb77e Bluetooth: Host: Remove unnecessary ifdef from cs.c
The building of cs.c based on the respective Kconfig option is already
taken care of CMakeLists.txt, so it's redundant to try to protect the code
through ifdefs in the c-file as well.

9ecca87281 Bluetooth: Host make the long workqueue stack size configurable
Add a prompt to the long workqueue stack size, so that it can be easily
fine-tuned by the application. The exact usage will depend on many factors,
such as the chosen crypto backend and target architecture, so it's not
possible to have "one size fits all" solutions based on the default values.

425f3f4b0a Bluetooth: Audio: Rename ctx type prohibited to none
The context type PROHIBITED has been removed from
the Bluetooth assigned numbers document. It is, however,
still used in some profiles to indicate either "No context
type supported" or "None available", and thus a rename
to "NONE" makes sense.

It is still treating similar to prohibited in some cases,
as it is not a valid context type in all cases.

fc14570585 Bluetooth: Controller: Fix Central CIS offset for dissimilar intervals
Fix Central CIS offset calculation for dissimilar ACL and
ISO intervals in use.

Mayfly execution of `mfy_cig_offset_get()` could be after
"LLL Prepare" or before depending on whether a previous radio
event is being preempted or not, respectively; the
`conn->lll.event_counter` may not be pre-incremented.
This race condition is fixed by the fact that we use a
constant instant delta value now.

Dissimilar ACL and ISO intervals may lead to ACL overlapping
or be too close to ISO event, causing preemption; under this
case ACLs "LLL Prepare" would run after `mfy_cig_offset_get`
causing incorrect calculation of CIS offset without the fix.

Remove redundant `instant` member in `ll_conn_iso_stream`
structure as a constant CIS Create instant delta is now
used.

PSA Crypto API always allow psa_generate_random() to be called (i.e. there

4a31b8036d Bluetooth: Host: Remove conditional stack size for BT_SETTINGS
With BT_SETTINGS enabled, there doesn't seem to (anymore?) be any
substantial overhead in stack consumption:

Let's just remove the conditional default and fall back to the
non-conditional one which is 1200.

6113230ce3 Bluetooth: drivers: Update to use new H:4 buffer encoding
Update all HCI drivers to use the new H:4 encoding for buffers passing
to/from drivers.

One behavioral change that's done in favor of simplicity, is that where
there's previously been switch statements that could return an error for
unsupported packet types now simply pass any received packet unchanged to
lower layers of the controller (or the HCI transport). Handling this is
now the responsibility of the lower layers, however in practice hitting
such scenarios means that there's a mismatch between configured host and
controller features.

- Add a public API function bt_rfcomm_send_rpn_cmd() to send RPN

- Add shell command to test RPN with default parameters

However this is a complex paramater struct that has

For this reason, the param is now stored in a single

does not need to be increased based on the Kconfig options,
as that is quite difficult for users to be aware of.

The add_src_param has been left as is, as that stored in
