+Realtek rtl8723bs Bluetooth controller
+======================================
+
+This documents the binding structure and properties for the serial
+attached rtl8723bs Bluetooth controller.
+
+Required properties:
+- compatible: must be "realtek,rt8723bs-bt"
+
+Optional properties:
+- enable-gpio: gpio line controlling the power down (BT_DIS#) signal
+- device-wake: gpio line controlling the device wakeup (BT_WAKE) signal
+- realtek,config-name: postfix added to the name of the firmware file
+  containing the chip configuration
+
+Example:
+
+&uart1 {
+	bluetooth {
+		compatible = "realtek,rtl8723bs-bt";
+		enable-gpio = <&r_pio 0 4 GPIO_ACTIVE_HIGH>; /* PL4 */
+		device-wake-gpio = <&r_pio 0 6 GPIO_ACTIVE_HIGH>; /* PL6 */
+		realtek,config-name = "olimex_a64_teres_i";
+	};
+};
