-Qualcomm Bluetooth Chips
----------------------
-
-This documents the binding structure and common properties for serial
-attached Qualcomm devices.
-
-Serial attached Qualcomm 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,qca9377-bt"
-   * "qcom,wcn3990-bt"
-   * "qcom,wcn3991-bt"
-   * "qcom,wcn3998-bt"
-   * "qcom,qca6390-bt"
-
-Optional properties for compatible string qcom,qca6174-bt:
-
- - enable-gpios: gpio specifier used to enable chip
- - clocks: clock provided to the controller (SUSCLK_32KHZ)
- - firmware-name: specify the name of nvm firmware to load
-
-Optional properties for compatible string qcom,qca9377-bt:
-
- - max-speed: see Documentation/devicetree/bindings/serial/serial.yaml
-
-Required properties for compatible string qcom,wcn399x-bt:
-
- - vddio-supply: VDD_IO supply regulator handle.
- - vddxo-supply: VDD_XO supply regulator handle.
- - vddrf-supply: VDD_RF supply regulator handle.
- - vddch0-supply: VDD_CH0 supply regulator handle.
-
-Optional properties for compatible string qcom,wcn399x-bt:
-
- - max-speed: see Documentation/devicetree/bindings/serial/serial.yaml
- - firmware-name: specify the name of nvm firmware to load
- - clocks: clock provided to the controller
-
-Examples:
-
-serial@7570000 {
-	label = "BT-UART";
-	status = "okay";
-
-	bluetooth {
-		compatible = "qcom,qca6174-bt";
-
-		enable-gpios = <&pm8994_gpios 19 GPIO_ACTIVE_HIGH>;
-		clocks = <&divclk4>;
-		firmware-name = "nvm_00440302.bin";
-	};
-};
-
-serial@898000 {
-	bluetooth {
-		compatible = "qcom,wcn3990-bt";
-
-		vddio-supply = <&vreg_s4a_1p8>;
-		vddxo-supply = <&vreg_l7a_1p8>;
-		vddrf-supply = <&vreg_l17a_1p3>;
-		vddch0-supply = <&vreg_l25a_3p3>;
-		max-speed = <3200000>;
-		firmware-name = "crnv21.bin";
-		clocks = <&rpmhcc RPMH_RF_CLK2>;
-	};
