4This documents the binding structure and common properties for serial
5attached Broadcom devices.
6
7Serial attached Broadcom devices shall be a child node of the host UART
8device the slave device is attached to.
9
10Required properties:
11
12 - compatible: should contain one of the following:
13   * "brcm,bcm43438-bt"
14
15Optional properties:
16
17 - max-speed: see Documentation/devicetree/bindings/serial/slave-device.txt
18 - shutdown-gpios: GPIO specifier, used to enable the BT module
19 - device-wakeup-gpios: GPIO specifier, used to wakeup the controller
20 - host-wakeup-gpios: GPIO specifier, used to wakeup the host processor
21 - clocks: clock specifier if external clock provided to the controller
22 - clock-names: should be "extclk"

25Example:
26
27&uart2 {
28       pinctrl-names = "default";
29       pinctrl-0 = <&uart2_pins>;

31       bluetooth {
32               compatible = "brcm,bcm43438-bt";
33               max-speed = <921600>;
34       };
35};
