 This documents the binding structure and common properties for serial

 Required properties:
  - compatible: should contain one of the following:
    * "qcom,qca6174-bt"
+   * "qcom,wcn3990-bt"
 
 Optional properties:
  - enable-gpios: gpio specifier used to enable chip
  - clocks: clock provided to the controller (SUSCLK_32KHZ)
-
-Example:
+ - vddpa-supply: Bluetooth VDD PA regulator handle
+ - vddio-supply: Bluetooth VDD IO regulator handle
+ - vddldo-supply: Bluetooth VDD LDO regulator handle. Kept under optional
+		  parameters as some of the chipsets doesn't require ldo or
+		  it may use from same vddio.
+ - vddxtal-supply: Bluetooth VDD XTAL regulator handle
+ - vddcore-supply: Bluetooth VDD CORE regulator handle
+ - vddpwd-supply: Chip power down gpio is required when bluetooth module
+		  and other modules like wifi co-exist in a singe chip and
+		  shares a common gpio to bring chip out of reset.
