Several Qualcomm projects will use the same Bluetooth chip, each focusing on different features. For instance, consumer projects prioritize the A2DP SRC feature, while IoT projects focus on the A2DP SINK feature. Due to the patch size, it is not feasible to include all features in a single firmware. Therefore, the 'product-variant' devicetree property is used to provide product information for the Bluetooth driver to load the appropriate firmware. The driver will parse 'product-variant' to load firmware from different directories. If it's not defined in dts, the default firmware will be loaded, which is compatible with the existing implementaion.
