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>;

       };

};
