Message

This series of patches adds support for BAP broadcast sink.
It consists in registering a broadcastsink endpoint using the
Basic Audio Announcement Service UUID,
discovering of broadcast advertisers that announce the
Broadcast Audio Announcement Service, synchronizes to the Periodic
advertisements of the source and synchronizes to the BIG advertised
in the PA train.
To retrieve the BASE info advertised in the PA train, the patch
Bluetooth: ISO: Add support for periodic adv reports processing
was used.

This feature was tested using bluetoothctl with the following commands:

[bluetooth]# endpoint.register 00001851-0000-1000-8000-00805f9b34fb 0x06
[bluetooth]# scan on
[NEW] Endpoint /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/pac_bcast0
[bluetooth]# endpoint.config
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/pac_bcast0
/local/endpoint/ep0 16_2_1
