Subject: [PATCH BlueZ v2 1/2] bap: use MediaEndpoint related properties consistently
Date:   Tue,  3 Oct 2023 20:49:13 +0300
Message-ID: <112613bc64e4d17573b75a9d245b5fe5e51b5fa1.1696354690.git.pav@iki.fi>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use the documented name "MaximumLatency" for the MediaEndpoint QoS
Max_Transport_Latency field, in SelectProperties input parameters and
expected client MediaEndpoint properties.

Put QoS fields to a "QoS" dict in SelectProperties input.

Use the name "Locations" for SelectProperties supported locations input
parameter, to match the MediaEndpoint property name which indicates the
same thing.

Notes:
    v2: put SelectProperties QoS things to "QoS" dict
