MediaTek UART based Bluetooth Devices
==================================
This device is a serial attached device to UART device and thus it must be a
child node of the serial node with UART.
Please refer to the following documents for generic properties:
Documentation/devicetree/bindings/serial/serial.yaml
Required properties:
- compatible: Must be
"mediatek,mt7663u-bluetooth": for MT7663U device
"mediatek,mt7668u-bluetooth": for MT7668U device
- vcc-supply: Main voltage regulator
If the pin controller on the platform can support both pinmux and GPIO
control such as the most of MediaTek platform. Please use below properties.
- pinctrl-names: Should be "default", "runtime"
- pinctrl-0: Should contain UART RXD low when the device is powered up to
enter proper bootstrap mode.
- pinctrl-1: Should contain UART mode pin ctrl
Else, the pin controller on the platform only can support pinmux control and
the GPIO control still has to rely on the dedicated GPIO controller such as
a legacy MediaTek SoC, MT7621. Please use the below properties.
- boot-gpios: GPIO same to the pin as UART RXD and used to keep LOW when
the device is powered up to enter proper bootstrap mode when
- pinctrl-names: Should be "default"
- pinctrl-0: Should contain UART mode pin ctrl
Optional properties:
- reset-gpios: GPIO used to reset the device whose initial state keeps low,
if the GPIO is missing, then board-level design should be
guaranteed.
- clocks: Should be the clock specifiers corresponding to the entry in
clock-names property. If the clock is missing, then board-level
design should be guaranteed.
- clock-names: Should contain "osc" entry for the external oscillator.
- current-speed: Current baud rate of the device whose defaults to 921600
Example:
uart1_pins_boot: uart1-default {
pins-dat {
pinmux = <MT7623_PIN_81_URXD1_FUNC_GPIO81>;
output-low;
};
};
uart1_pins_runtime: uart1-runtime {
pins-dat {
pinmux = <MT7623_PIN_81_URXD1_FUNC_URXD1>,
<MT7623_PIN_82_UTXD1_FUNC_UTXD1>;
};

"mediatek,mt6577-uart";
reg = <0 0x11003000 0 0x400>;
interrupts = <GIC_SPI 52 IRQ_TYPE_LEVEL_LOW>;
clocks = <&pericfg CLK_PERI_UART1_SEL>,

Nokia Bluetooth Chips
---------------------
Nokia phones often come with UART connected bluetooth chips from different
vendors and modified device API. Those devices speak a protocol named H4+
(also known as h4p) by Nokia, which is similar to the H4 protocol from the
Bluetooth standard. In addition to the H4 protocol it specifies two more
UART status lines for wakeup of UART transceivers to improve power management
and a few new packet types used to negotiate uart speed.
Required properties:
- compatible: should contain "nokia,h4p-bluetooth" as well as one of the following:
* "brcm,bcm2048-nokia"
* "ti,wl1271-bluetooth-nokia"
- reset-gpios: GPIO specifier, used to reset the BT module (active low)
- bluetooth-wakeup-gpios: GPIO specifier, used to wakeup the BT module (active high)
- host-wakeup-gpios: GPIO specifier, used to wakeup the host processor (active high)
- clock-names: should be "sysclk"
- clocks: should contain a clock specifier for every name in clock-names
Optional properties:
- None
Example:
/ {
/* controlled (enabled/disabled) directly by BT module */
bluetooth_clk: vctcxo {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <38400000>;

This binding describes UART-attached NXP bluetooth chips. These chips
are dual-radio chips supporting WiFi and Bluetooth. The bluetooth
works on standard H4 protocol over 4-wire UART. The RTS and CTS lines
are used during FW download. To enable power save mode, the host
asserts break signal over UART-TX line to put the chip into power save
state. De-asserting break wakes up the BT chip.

description: |
This documents the binding structure and common properties for serial
attached TI Bluetooth devices. The following chips are included in this
binding:
* TI CC256x Bluetooth devices
* TI WiLink 7/8 (wl12xx/wl18xx) Shared Transport BT/FM/GPS devices
TI WiLink devices have a UART interface for providing Bluetooth, FM radio,
and GPS over what's called "shared transport". The shared transport is
standard BT HCI protocol with additional channels for the other functions.
TI WiLink devices also have a separate WiFi interface as described in
wireless/ti,wlcore.yaml.
This bindings follows the UART slave device binding in ../serial/serial.yaml.
