7c22073195 Bluetooth: controller: Make worker and job priority configurable
Add Controller advanced Kconfig options to select IRQ
priorities of the Radio, Ticker's Worker and JOB IRQs.

This will provide an opportunity to have peripheral IRQ's
of higher level than Bluetooth Controller.

f38d57cba3 Bluetooth: controller: Kconfig option for advanced scheduling
Add Kconfig option to enable advanced scheduling in the
controller.

Enable non-overlapping placement of observer, initiator and
master roles in timespace. Uses window offset in connection
updates and uses connection parameter request in slave role
to negotiate non-overlapping placement with active master
roles to avoid slave roles drifting into active master
roles in the local controller.

This feature maximizes the average data transmission amongst
active concurrent master and slave connections while other
observer, initiator, master or slave roles are active in the
local controller.

Disabling this feature will lead to overlapping role in
timespace leading to skipped events amongst active roles.

646726518f Bluetooth: controller: Kconfig for advanced event preparation
Added Kconfig option to enable advanced event preparation
feature.

Enables advanced event preparation offset ahead of radio
tx/rx, taking into account predictive processing time
requirements in preparation to the event, like control
procedure handling and CPU execution speeds. Crystal
oscillator is retained between closely spaced consecutive
radio events to reduce the overall number of crystal
settling current consumptions.

This feature maximizes radio utilization in an average role
event timeslice when they are closely spaced by using a
reduced offset between preparation and radio event.

By disabling this feature, the controller will use a
constant offset between the preparation and radio event. The
controller will toggle crystal oscillator between two
closely spaced radio events leading to higher average
current due to increased number of crystal settling current
consumptions.

611460b913 Bluetooth: controller: Fix race waiting for ticker job to complt
Same volatile status variable as return and being updated
in ISR would modify the variable in two context which
caused the variable to be set to a stale value.

This commit uses two different variables, one for return
value and the other to be updated by ISR.

2d644f2f42 Bluetooth: controller: Fix mayfly caller id for thread call path
role_disable initiated through HCI commands are initiated
in thread context and controller code was using the job
mayfly caller id instead of using the correct app caller
id.

Also the XTAL retain calls being called from two different
call context used the same worker caller id and same mayfly
instead of using the correct caller ids and independent
mayfly for each caller.

This potentially could cause mayfly enqueued list to be
corrupted and enqueued mayfly could be lost.

than little-endian. Introduce a native big-endian API to avoid
excessive byte order reversals in these cases.

4b10d75fbe Bluetooth: controller: Move LL code from driver to ll_sw
The current hci_driver.c contained all the software Link Layer
initialization code. To decouple HCI from the actual LL, most of the
functionality that is actually part of the LL has been moved to the
ll_sw folder, opening the possibility for future hardware-based LL
implementations.
