+* Bluetooth Controller
+Bluetooth controller communicates with the Bluetooth Host using HCI Transport layer.
+HCI Transport layer can be based on UART or USB serial communication protocol.
+
+Required properties:
+ - compatible: Should be set to one of the following:
+ qca,ar3002
+ qca,qca6174
+ qca,wcn3990
+
+Optional properties:
+ - 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.
+
+Example:
+ bt-ar3002 {
+ compatible = "qca,ar3002";
+ vddio-supply = <&pm8941_s3>;
+ vddpa-supply = <&pm8941_l19>;
+ vddxtal-supply = <&pm8994_l30>;
+ vddcore-supply = <&pm8994_s3>;
+ vddpwd-supply = <&ath_chip_pwd_l>;
+};
