This documents the binding structure and common properties for serial
-attached Qualcomm devices.

+Serial attached Qualcomm Technologies Inc devices shall be a child node
+of the host UART device the slave device is attached to.
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.
