From ca6d2adf8ded3eb3e64a01f339735c99e6c7260e Mon Sep 17 00:00:00 2001 From: Zijun Hu Date: Fri, 8 Dec 2023 09:51:27 +0800 Subject: [PATCH] Bluetooth: qca: Support HFP offload for QCA2066 For QCA2066 HFP offload, HCI_Configure_Data_Path is not required since present HCI_Enhanced_Setup_Synchronous_Connection is enough to configure non-HCI data transport path when set both Input_Data_Path and Output_Data_Path parameters as 0x01, as is implemented by this change.
