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";
};
};
