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>; }; };
