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