-MediaTek SoC built-in Bluetooth Devices
-==================================
-
-This device is a serial attached device to BTIF device and thus it must be a
-child node of the serial node with BTIF. The dt-bindings details for BTIF
-device can be known via Documentation/devicetree/bindings/serial/8250.txt.
-
-Required properties:
-
-- compatible:	Must be
-		  "mediatek,mt7622-bluetooth": for MT7622 SoC
-- clocks:	Should be the clock specifiers corresponding to the entry in
-		clock-names property.
-- clock-names:	Should contain "ref" entries.
-- power-domains: Phandle to the power domain that the device is part of
-
-Example:
-
-	btif: serial@1100c000 {
-		compatible = "mediatek,mt7622-btif",
-			     "mediatek,mtk-btif";
-		reg = <0 0x1100c000 0 0x1000>;
-		interrupts = <GIC_SPI 90 IRQ_TYPE_LEVEL_LOW>;
-		clocks = <&pericfg CLK_PERI_BTIF_PD>;
-		clock-names = "main";
-		reg-shift = <2>;
-		reg-io-width = <4>;
-
-		bluetooth {
-			compatible = "mediatek,mt7622-bluetooth";
-			power-domains = <&scpsys MT7622_POWER_DOMAIN_WB>;
-			clocks = <&clk25m>;
-			clock-names = "ref";

-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
-
-If the pin controller on the platform can support both pinmux and GPIO
-control such as the most of MediaTek platform. Please use below properties.
-
-- 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
-
-Else, the pin controller on the platform only can support pinmux control and
-the GPIO control still has to rely on the dedicated GPIO controller such as
-a legacy MediaTek SoC, MT7621. Please use the below properties.
-
-- boot-gpios:	GPIO same to the pin as UART RXD and used to keep LOW when
-		the device is powered up to enter proper bootstrap mode when
-- pinctrl-names: Should be "default"
-- pinctrl-0: 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.
-- clocks:	Should be the clock specifiers corresponding to the entry in
-		clock-names property. If the clock is missing, then board-level
-		design should be guaranteed.
-- clock-names:	Should contain "osc" entry for the external oscillator.
-- current-speed:  Current baud rate of the device whose defaults to 921600

-	uart1_pins_boot: uart1-default {
