+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 one of
+ "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";
+ };
+ };
