Serial Slave Device DT binding
This documents the binding structure and common properties for serial
attached devices. Common examples include Bluetooth, WiFi, NFC and GPS
devices.
Serial attached devices shall be a child node of the host UART device the
slave device is attached to. It is expected that the attached device is
the only child node of the UART device. The slave device node name shall
reflect the generic type of device for the node.
Required Properties:
- compatible : A string reflecting the vendor and specific device the node
represents.
Optional Properties:
- max-speed : The maximum baud rate the device operates at. This should
only be present if the maximum is less than the slave device
can support. For example, a particular board has some signal
quality issue or the host processor can't support higher
baud rates.
Example:
serial@1234 {
compatible = "ns16550a";
interrupts = <1>;
bluetooth {
compatible = "brcm,bcm43341-bt";
interrupt-parent = <&gpio>;
interrupts = <10>;
};
};
