[PATCH v3 0/2] Bluetooth: hci_qca: Refactor HFP hardware offload capability handling

[Mengshi Wu]

Changes from v3:
 - Add QCA_CAP_HFP_HW_OFFLOAD capability flag to WCN7850

Changes from v2:
 - Add QCA_CAP_HFP_HW_OFFLOAD capability flag at first commit to avoid
   breaking original logic.
 - Link to v2:
   https://lore.kernel.org/all/20260126162444.4194293-1-mengshi.wu@oss.qualcomm.com/

Changes from v1:
 - Refactor HFP hardware offload capability handling.
 - Enable HFP hardware offload for QCA2066 and WCN6855.
 - Link to v1:
   https://lore.kernel.org/all/20260123055243.2634107-1-mengshi.wu@oss.qualcomm.com/

[PATCH v3 1/2] Bluetooth: hci_qca: Refactor HFP hardware offload capability handling

[Mengshi Wu]

Replace SoC-specific check with capability-based approach for HFP
hardware offload configuration. Add QCA_CAP_HFP_HW_OFFLOAD capability
flag and support_hfp_hw_offload field to qca_serdev structure. Add
QCA_CAP_HFP_HW_OFFLOAD capability flag to QCA2066 device data
structures.
