+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"
+
+Optional properties:
+
+ - bt-disable-n-gpios: GPIO specifier, used to enable chip during probe
+
+Example:
+
+serial@7570000 {
+ pinctrl-names = "default", "sleep";
+ pinctrl-0 = <&blsp1_uart1_default>;
+ pinctrl-1 = <&blsp1_uart1_sleep>;
+
+ bluetooth {
+ compatible = "qcom,qca6174-bt";
+
+ bt-disable-n-gpios = <&pm8994_gpios 19 GPIO_ACTIVE_HIGH>;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&bt_en_pin_a>, <&divclk4_pin_a>;
+ };
+};
