Broadcom Bluetooth Chips
---------------------
This documents the binding structure and common properties for serial
attached Broadcom devices.
Serial attached Broadcom devices shall be a child node of the host UART
device the slave device is attached to.
Required properties:
- compatible: should contain one of the following:
* "brcm,bcm43438-bt"
Optional properties:
- max-speed: see Documentation/devicetree/bindings/serial/slave-device.txt
- shutdown-gpios: GPIO specifier, used to enable the BT module
- device-wakeup-gpios: GPIO specifier, used to wakeup the controller
- host-wakeup-gpios: GPIO specifier, used to wakeup the host processor
- clocks: clock specifier if external clock provided to the controller
- clock-names: should be "extclk"
Example:
&uart2 {
pinctrl-names = "default";
pinctrl-0 = <&uart2_pins>;
bluetooth {
compatible = "brcm,bcm43438-bt";
max-speed = <921600>;
};
};
