    Subject[PATCH v6 1/4] dt-bindings: net: bluetooth: Add mediatek-bluetooth
    Date
    From: Sean Wang <sean.wang@mediatek.com>

    Add binding document for a SoC built-in device using MediaTek protocol.
    Which could be found on MT7622 SoC or other similar MediaTek SoCs.

    +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";
    + };
    + };
