One big Qualcomm Bluetooth schema is hardly manageable: it lists all possible properties (19 supplies). Split qcom,wcn3990-bt to separate bindings, so device schema will be easier to read/maintain and list only relevant properties. This binding is very similar to qcom,wcn3950-bt, however devices have additional VDD_CH1 supply.
