Kumar Gala d0eb235510 Bluetooth: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

Kumar Gala 3c454017b4 Merge "Merge bluetooth branch into master" 2017-04-20 16:55:36 +00:00
Kumar Gala 789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Vinayak Chettimada 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.

Vinayak Chettimada 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.
