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";

		};

	};
