The rtl_bt driver already supports some Realtek controllers on ACPI
platforms.
This commit adds bindings for DT-only platforms.

+Realtek Bluetooth controllers
+=============================
+
+This documents the binding structure and properties for the serial
+attached Bluetooth controllers from Realtek.
+
+Required properties:
+- compatible: currently, only "realtek,rt8723bs-bt" is supported
+
+Optional properties:
+- enable-gpio: gpio line controlling the power down (BT_DIS#) signal
+- device-wake: gpio line controlling the device wakeup (BT_WAKE) signal
+- 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 */
+ config-name = "teres_a64_i";
+ };
+};
