1 Broadcom Bluetooth Chips
4 This documents the binding structure and common properties for serial
5 attached Broadcom devices.
7 Serial attached Broadcom devices shall be a child node of the host UART
8 device the slave device is attached to.
12 - compatible: should contain one of the following:
19 - max-speed: see Documentation/devicetree/bindings/serial/slave-device.txt
20 - shutdown-gpios: GPIO specifier, used to enable the BT module
21 - device-wakeup-gpios: GPIO specifier, used to wakeup the controller
22 - host-wakeup-gpios: GPIO specifier, used to wakeup the host processor
23 - clocks: 1 or 2 clocks as defined in clock-names below, in that order
24 - clock-names: names for clock inputs, matching the clocks given
25 - "extclk": deprecated, replaced by "txco"
26 - "txco": external reference clock (not a standalone crystal)
27 - "lpo": external low power 32.768 kHz clock
28 - vbat-supply: phandle to regulator supply for VBAT
29 - vddio-supply: phandle to regulator supply for VDDIO
35 pinctrl-names = "default";
36 pinctrl-0 = <&uart2_pins>;
39 compatible = "brcm,bcm43438-bt";
