Larry Finger July 21, 2017, 4:24 a.m. UTC
From: Ping-Ke Shih <pkshih@realtek.com>

The older related functions are get_bt_patch_version and set_bt_reg.
The new functions are get_supported_feature, get_supported_version,
get_ant_det_val, ble_scan_type and ble_scan_para.
Also, add a wait parameter, so it can be a synchronized call.
