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.
