584bd4069f Bluetooth: controller: Kconfig for event length update
Since the event length update is not necessarily an improvement
in all situations a Kconfig option is added so that it can
be disabled for the users that do not need it.

7daba33f2d Bluetooth: controller: llcp: update max dle times on feature exchange
On a completion of feature exchange the max DLE times needs to be
updated if Coded PHY has become supported.
For this now also keep a separate store of the default_tx_octets/time
for the sake of re-calculation of local versions of DLE values

c5812bab5e Bluetooth: Controller: Add Kconfig to enable CTE RX in conn mode
The CTE reception and sampling in connected mode was enabled
with CONFIG_BT_CTLR_DF_CONN_CTE_REQ. This is a separate fearure
tha can be enabled when CTE reqest procedure is disabled.
What more the CONFIG_BT_CTLR_DF_CONN_CTE_REQ is dependent
on CONFIG_BT_CTLR_DF_CONN_CTE_RX, not other way around.

The commit adds separate Kconfig to provide such possibility.
Also changes compilation guards for code related with the
CTE reception and sampling.

f023b5f611 Bluetooth: controller: push topic branch to main
Pushes all work done in the topic-ble-llcp branch into main branch
This is a refactoring of the LL control procedures; the refactored
control procedures are hidden behind a KConfig option and
per default disabled

Goal of the refactoring:

close issue Link Layer Control Procedure overhaul #15256
make it easier to add/update control procedures
Refactoring consists in principal of writing explicit state machines
for the control procedures.
To reduce the risk of regression errors unit-tests have been added

Following control procedures are implemented:

Connection update procedure
Channel map update procedure
Encryption procedure
Feature exchange procedure
Version exchange procedure
ACL termination procedure
Connection parameters request procedure
LE Ping procedure
Data Length Update procedure
PHY update procedure
Min. nr. Of channels used procedure
Constant Tone extension request procedure

07278fc98f Bluetooth: controller: Guard against race in conn. establishment
In the time between a NODE_RX_TYPE_CONNECTION node is sent from LLL and
demuxed in ULL, an ADV role disable may be executed.
This makes the LLL data referenced in the node NULL/invald, and
ull_conn_setup would operate on invalid data.

This commit introduces a check in ADV disable to disallow the operation
(including conn invalidation), if a connection has been initiated.

To prevent pipeline-queued prepares from advertising after disable has
been initiated, set 'cancelled' flag for immediate signalling to LLL.

abd1d047dd Bluetooth: controller: enable dynamic TXP over LL_SPLIT arch (#17731)
This commit targets solving issue #17731 over the LL_SW_SPLIT
arch of the BLE stack in Zephyr. This functionality is exposed
to the user as HCI Zephyr Command extensions

- BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL
- BT_HCI_OP_VS_READ_TX_POWER_LEVEL

which enable Tx power read/write operations within BLE radio events
on a per role/connection basis.

The functionality is enabled upon the Kconfig advanced configuration
triggered by

- BT_CTLR_TX_PWR_DYNAMIC_CONTROL

depending on the enablement of Zephyr HCI vendor-specific command
extensions.

Necessary low-level radio HAL functionality and power definitions
are also supplied to address the high-level functionality of
controlling the Tx power.

1475402d41 Bluetooth: controller: Introduce ULL LLL architecture
This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.

This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.

The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.
