+MediaTek UART based Bluetooth Devices
+==================================
+
+This device is a serial attached device to UART device and thus it must be a
+child node of the serial node with UART.
+
+Please refer to the following documents for generic properties:
+
+	Documentation/devicetree/bindings/serial/slave-device.txt
+
+Required properties:
+
+- compatible:	Must be
+		  "mediatek,mt7663u-bluetooth": for MT7663U device
+		  "mediatek,mt7668u-bluetooth": for MT7668U device
+- vcc-supply:	Main voltage regulator
+- pinctrl-names: Should be "default", "runtime"
+- pinctrl-0: Should contain UART RXD low when the device is powered up to
+	     enter proper bootstrap mode.
+- pinctrl-1: Should contain UART mode pin ctrl
+
+Optional properties:
+
+- reset-gpios:	GPIO used to reset the device whose initial state keeps low,
+		if the GPIO is missing, then board-level design should be
+		guaranteed.
+- current-speed:  Current baud rate of the device whose defaults to 921600
+
+Example:
+
+	uart1_pins_boot: uart1-default {
+		pins-dat {
+			pinmux = <MT7623_PIN_81_URXD1_FUNC_GPIO81>;
+			output-low;
