Description
***********
.. code-block:: none
CYW43xxx Connectivity that uses Zephyr's Bluetooth Host Controller Interface UART
driver.
Example of enabling CYW43xxx device:
&uart2 {
status = "okay";
current-speed = <115200>;
/* HCI-UART pins*/
pinctrl-0 = <&p3_1_scb2_uart_tx &p3_0_scb2_uart_rx
&p3_2_scb2_uart_rts &p3_3_scb2_uart_cts>;
pinctrl-names = "default";
bt-hci {
status = "okay";
compatible = "infineon,cyw43xxx-bt-hci";
bt-reg-on-gpios = <&gpio_prt3 4 (GPIO_ACTIVE_HIGH)>;
fw-download-speed = <3000000>;
};
};
NOTE1: The UART bus speed (current_speed) for zephyr_bt_uart should be the same
as the default baudrate defined in CYW43xx firmware (default 115200).
NOTE2: Use fw-download-speed and hci-operation-speed properties to configure UART
speeds for firmware download (fw-download-speed) and HCI operation
(hci-operation-speed).
If hci-operation-speed or fw-download-speed are not defined in bt-hci node,
cyw43xx driver will use bus/current-speed as default speed.
NOTE3: CYW43xxx requires fetch binary files of BT controller. To fetch binary blobs:
west blobs fetch hal_infineon

Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.

Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
* - ``zephyr,pm-device-runtime-auto``
- ``boolean``
- .. code-block:: none
Automatically configure the device for runtime power management after the
init function runs.
