      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.yaml.
      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	};

     37MediaTek UART based Bluetooth Devices
     38==================================
     39
     40This device is a serial attached device to UART device and thus it must be a
     41child node of the serial node with UART.
     42
     43Please refer to the following documents for generic properties:
     44
     45	Documentation/devicetree/bindings/serial/serial.yaml
     46
     47Required properties:
     48
     49- compatible:	Must be
     50		  "mediatek,mt7663u-bluetooth": for MT7663U device
     51		  "mediatek,mt7668u-bluetooth": for MT7668U device
     52- vcc-supply:	Main voltage regulator
     53
     54If the pin controller on the platform can support both pinmux and GPIO
     55control such as the most of MediaTek platform. Please use below properties.
     56
     57- pinctrl-names: Should be "default", "runtime"
     58- pinctrl-0: Should contain UART RXD low when the device is powered up to
     59	     enter proper bootstrap mode.
     60- pinctrl-1: Should contain UART mode pin ctrl
     61
     62Else, the pin controller on the platform only can support pinmux control and
     63the GPIO control still has to rely on the dedicated GPIO controller such as
     64a legacy MediaTek SoC, MT7621. Please use the below properties.
     65
     66- boot-gpios:	GPIO same to the pin as UART RXD and used to keep LOW when
     67		the device is powered up to enter proper bootstrap mode when
     68- pinctrl-names: Should be "default"
     69- pinctrl-0: Should contain UART mode pin ctrl
     70
     71Optional properties:
     72
     73- reset-gpios:	GPIO used to reset the device whose initial state keeps low,
     74		if the GPIO is missing, then board-level design should be
     75		guaranteed.
     76- clocks:	Should be the clock specifiers corresponding to the entry in
     77		clock-names property. If the clock is missing, then board-level
     78		design should be guaranteed.
     79- clock-names:	Should contain "osc" entry for the external oscillator.
     80- current-speed:  Current baud rate of the device whose defaults to 921600
     81
     82Example:
     83
     84	uart1_pins_boot: uart1-default {
     85		pins-dat {
     86			pinmux = <MT7623_PIN_81_URXD1_FUNC_GPIO81>;
     87			output-low;
     88		};
     89	};
     90
     91	uart1_pins_runtime: uart1-runtime {
     92		pins-dat {
     93			pinmux = <MT7623_PIN_81_URXD1_FUNC_URXD1>,
     94				 <MT7623_PIN_82_UTXD1_FUNC_UTXD1>;
     95		};
     96	};
