1MediaTek SoC built-in Bluetooth Devices 2================================== 3 4This device is a serial attached device to BTIF device and thus it must be a 5child node of the serial node with BTIF. The dt-bindings details for BTIF 6device can be known via Documentation/devicetree/bindings/serial/8250.txt. 7 8Required properties: 9 10- compatible: Must be 11 "mediatek,mt7622-bluetooth": for MT7622 SoC 12- clocks: Should be the clock specifiers corresponding to the entry in 13 clock-names property. 14- clock-names: Should contain "ref" entries. 15- power-domains: Phandle to the power domain that the device is part of 16 17Example: 18 19 btif: serial@1100c000 { 20 compatible = "mediatek,mt7622-btif", 21 "mediatek,mtk-btif"; 22 reg = <0 0x1100c000 0 0x1000>; 23 interrupts = <GIC_SPI 90 IRQ_TYPE_LEVEL_LOW>; 24 clocks = <&pericfg CLK_PERI_BTIF_PD>; 25 clock-names = "main"; 26 reg-shift = <2>; 27 reg-io-width = <4>; 28 29 bluetooth { 30 compatible = "mediatek,mt7622-bluetooth"; 31 power-domains = <&scpsys MT7622_POWER_DOMAIN_WB>; 32 clocks = <&clk25m>; 33 clock-names = "ref"; 34 }; 35 }; 36
