Joakim Andersson 291ebdd4e4 Bluetooth: Fix infinite recursion in host-based bt_rand
Fix infinite recursion in host-based bt_rand function. This would call
HCI LE Random Number command, which would in turn call bt_rand, causing
an infinite recursion.

bt_rand -> prng_reseed -> BT_HCI_OP_LE_RAND -> le_rand -> bt_rand

To solve this issue the controller should avoid doing calls into the
host, so all calls to bt_rand in the controller should be replaced with
a call to a controller function.

Fixes #22202

SMI TX is different than other controller features in that it does not
necessarily imply any software changes; whether SMI TX is supported
may be simply a matter of hardware calibration. This change supports

Morten Priess 64c89d682f bluetooth: controller: Implemented dynamic re-scheduling in ticker
As a part of a ticker extension interface, it is now possible to specify
a slot_window when starting a ticker. When setting the
ticks_slot_window to a non-zero value, it is requested that the node
timeout is re-located to a position within the window, where the node
does not collide with other nodes - aligning to the end of the window.
The solution takes into consideration if a node has already been
updated with drift correction (e.g. ADV randomization), subtracting this
from the window.

Zephyr aims to enable supporting of multiple SW defined
BLE LL. There is a complex hierarchy of defines in the
CMake files controlling the compilation units that part of
the final library. Adding another SW LL implementation
from a different SoC provider will make the main controller
CMake file unmaintable.

Ulf Magnusson 4e85006ba4 dts: Rename generated_dts_board*.{h,conf} to devicetree*.{h,conf}
generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.

dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.

The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.

Two build diagram and input-output SVG files were updated as well, along
with misc. documentation.

hal_ti, mcuboot, and ci-tools updates are included too, in the west.yml
update.

Vinayak Kariappa Chettimada b5c63c69ca Bluetooth: controller: split: Fix ull_disable hang
Under race conditions it is possible that there is no call
to k_sem_give to the waiting k_sem_take in the ull_disable
function.

ull_disable function checks for reference count before
using a mayfly to schedule lll_disable, which in turn
would close requested currently active role event leading
to done event being propogated to ULL. Done event would
then call the set disabled_cb callback when the reference
count is zero, giving the semaphore to the waiting
k_sem_give in the ull_disable.

Under race conditions if the reference count reached zero
after the reference count check and before the disabled_cb
was assigned in the ull_disable function, then there are
chances that a k_sem_give is not called while ull_disable
proceeds to waiting using k_sem_take.

Fixes #21586.

Vinayak Kariappa Chettimada f8877e39ce Bluetooth: controller: legacy: Fix controller address check
Fix controllers address check in cases of controller-based privacy.
When controller has been instructed by the host to use privacy
the controller should look up the peer identity address and generate
an address based on the local IRK. In the case where no match
is found or the local IRK is all zeroes the controller shall use
the fallback address. If the fallback address is not valid the
controller shall return invalid params.

This commit fixes these issues:
 - Starting a private advertiser without valid random address set
   but a valid local IRK exists. In this case the advertiser should
   be able to advertise using the RPA regardless of a valid random
   or public address.
 - Starting a private advertiser with a fallback to the public
   address type or an adveriser using public address  does not
   check if a valid public address exists. The host cannot
   advertise with an all-zero public address.

Krzysztof Chruscinski 00156ad80a drivers: clock_control: nrf: Switch to single clock device
Low frequency and high frequency clocks had separate devices
while they are actually handled by single peripheral with single
interrupt. The split was done probably because opaque subsys
argument in the API was used for other purposes and there was
no way to pass the information which clock should be controlled.
Implementation changes some time ago and subsys parameter was
no longer used. It now can be used to indicate which clock should
be controlled.

Change become necessary when nrf5340 is taken into account where
there are more clocks and current approach would lead to create
multiple devices - mess.
