Subject: [PATCH v2 4/4] Bluetooth: hci_qca: add qcom,product-variant properties
Since different products use the same SoC chip, features cannot
be included in a single patch. Use the qcom,product-variant to
load the appropriate firmware.
The qcom,product-variant provides product line information, which
the driver uses to load firmware from different directories.
If it's not defined in dts, the default firmware will be loaded.
Signed-off-by: Cheng Jiang <quic_chejiang@...cinc.com>
