| 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>; | |
| }; | |
| }; |
