[PATCH BlueZ v1] bap: Don't attempt to release if old state was releasing

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

If the old state was releasing there is no reason to call
bt_bap_stream_release yet again when IO could not be created as that
will likely create a loop situation when the remote stack caches the
codec configuration.

[PATCH BlueZ v2 1/6] bap: Allow setup of multiple stream per endpoint

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Remote endpoints actually represents PAC records of the same codec and
their capabilities are merged together thus is should be possible to
create multiple streams depending on the AC configuration.

[PATCH BlueZ v2 2/6] shared/bap: Make bt_bap_select match the channel map

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

bt_bap_pac may actually map to multiple PAC records and each may have a
different channel count that needs to be matched separately, for
instance when trying with EarFun Air Pro:

[PATCH BlueZ v2 3/6] org.bluez.MediaEndpoint: Add ChannelAllocation to SelectProperties

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This adds ChannelAllocation to SelectProperties which when set can be
used by Endpoint implementation in the response as part of
Capabilities, note that it is not mandatory to use it so the Endpoint
may have its on logic to allocate channels.

[PATCH BlueZ v2 4/6] shared/bap: Make bt_bap_select select a location

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This makes bt_bap_select select a location based on the PAC channel
count and PACS locations, this is then passed to the Endpoint as a
recommended ChannelAllocation.

[PATCH BlueZ v2 5/6] shared/bap: Fix stream IO linking

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

IO linking shall only be possible once, for the oposite direction as ISO
channels are bidirection, and not many times as that means multiplexing
would be used which is done within the transport payload, so this get rid
of queue links list and just use single link point instead.

[PATCH BlueZ v2 6/6] client/player: Use ChannelAllocation given on SelectProperties

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This makes use of ChannelAllocation when present on SelectProperties
dictionary which is then passed on to bluetoothd and send over as part
of Codec Configuration:
