737cab2614 Bluetooth: controller: openisa: Check preempt event on timeout
Check whether the preempt event matches with the head of the
pipeline before aborting the currently active event.

This is required to avoid preemption of events that became

82925a8c99 Bluetooth: controller: Avoid sizeof to access ULL/LLL struct member
Avoid using sizeof to access ULL and LLL struct members.
Based on the alignment requirements of structures, due to
padding between structure members, use of sizeof of previous
struct member to access next struct member is incorrect.

Continue to use explicitly stored parent pointer to access
ULL context. Combine event header and ULL header so that
the parent pointer point directly to the combined ULL
struct.

Move LLL header files for all roles to common folder. Move
vendor-specific content to internal header files, in particular ADV
buffer handling. Define the vendor-specific type lll_adv_pdu in a

moving ADV buffer handling to internal header file. Make sure all

4b600fcf9a Bluetooth: controller: Remove assert in functions that get latest adv. PDU
Remove LL_ASSERT from functions that return latest advertising PDU.
The LL_ASSERT was raised in situation that there is no memory to
store unused PDUs memory in a pdu_free queue or extra_data_free queue
Those functions return NULL in such sitation. The returned value is
verified by callers by LL_ASSERT. That gives better context if lack
of memory issue issue occurs.

Besides that there was removed a LL_ASSERT from lll_adv_pdu_and_extra_-
data_alloc. The reasons is the same as above, to give better context
when the lack of memory issue occurs.
This function is used in ULL context (ll_adv_sync_ad_data_set).
If it returns NULL the caller will return BT_HCI_ERR_MEM_CAPACITY_-
EXCEEDED to Host.

4dcfb5531c isr: Normalize usage of device instance through ISR
The goal of this patch is to replace the 'void *' parameter by 'struct

When device privacy is enabled then ull_filter_lll_rl_addr_allowed will

When the directed advertiser is not privacy enabled then lll->rl_idx is

The check rl_idx != lll->rl_idx will then fail (0 != 0xff) and the
connect request is denied, even though all addresses matches on-air.

This is a rework for OpenISA SW LL of
"4547bfb452 Bluetooth: controller: split: handle latency for cancelled
conn events" as well as subsequent fixes

Update implementation of master and slave LLL's to correctly
handle event counter values when latencies introduced due to
connection events cancelled by active events operating in
unreserved time space.

When an active radio event extends into unreserved time
space, and a connection event prepare is scheduled but at
the time of pre-emption timeout if the connection event is
cancelled then the event count and latencies needs to be
continiued to get acummulated.

In the current controller usecases the above scenarios does
not get exercised, the changes in this commit is needed for
future roles that can extend into unreserved time space and
would cancel a scheduled connection event.

6099e0f928 bluetooth: controller: openisa/RV32M1: add RPA support
The radio on the VEGA platform will now be able to resolve Resolvable
Private Addresses through the use of the CAUv3 hardware. With this
patch the RPA feature is now fully supported on the Controller:
RPA addresses are generated with local IRK and resolved with
previously exchanged peer IRK.

60541af791 Bluetooth: controller: specify entropy device explicitly
For the ll code we know the exact entropy device as its the one for the
SoC that we are on.  So use the new DT macro's to get the entropy device
via DT_INST rather than using CONFIG_ENTROPY_NAME.

Remove use of k_cpu_idle in controller, and refactor the
implementation used to start, wait and stop clocks needed
by the controller.

cb0a6c2eff bluetooth: controller: openisa/RV32M1: add 2 Mbps PHY support
The radio on the VEGA platform supports both 1Mbps, as well
as 2Mbps BLE PHYs. It does not support coded BLE PHY. This patch
adds the necessary callback, as well as timings to enable the 2 Mbps
PHY support in the SW LL HAL for VEGA.

f8293807da bluetooth: controller: openisa/RV32M1: fix LL scheduling
- avoid spourious radio interrupts by fixing ISR set,
    waiting for idle, command configuration
- adjust counter to account for missing increment
- change preemption instant to avoid missing the deadline in LLL
- decrese EVENT_JITTER_US and
    EVENT_TICKER_RES_MARGIN_US (same as Nordic)

Continuous scanning and connections are working fine now.
