+Device-Tree bindings for MediaTek BTIF controller found on those
+MediaTek SoCs with Bluetooth feature
+
+Required properties:
+- compatible: Should be one of:
+ - "mediatek,mt7622-btif" : for MT7622 SoC
+ - "mediatek,mt7623-btif" : for MT7623 SoC
+- reg: The base address of the BTIF register bank;
+- interrupts: A single interrupt specifier;
+- clocks: list of clock specifiers, corresponding to
+ entries in clock-names property;
+- clock-names: should contain "main" entries.
+
+Optional properties:
+- mediatek,loopback: Boolean; if defined, indicates that BTIF controller
+ running on the loopback mode.
+
+Example:
+
+ btif: btif@1100c000 {
+ compatible = "mediatek,mt7623-btif";
+ reg = <0 0x1100c000 0 0x1000>;
+ interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_LOW>;
+ clocks = <&pericfg CLK_PERI_BTIF>;
+ clock-names = "main";
+ };
