Subject: [PATCH v4 1/2] Bluetooth: hci_qca: Added support for WCN3998
Added new compatible for WCN3998 and corresponding voltage
and current values to WCN3998 compatible.
Changed driver code to support WCN3998
Signed-off-by: Harish Bandi <c-hbandi@...eaurora.org>
---
Changes in V4:
- Added is_qca_soc_type_wcn399x_family helper function
- to get the soc type is wcn399x or not.
