####################################
Vendor: :ref:`Zephyr-specific binding `
Description
***********
.. code-block:: none
Configures SPI slave settings for a Bluetooth controller that uses
Zephyr's Bluetooth Host Controller Interface SPI (HCI SPI) driver.
A node defined via devicetree overlay should look like this:
&myspi {
bt-hci@0 {
compatible = "zephyr,bt-hci-spi-slave";
reg = <0>;
irq-gpios = <&gpio1 2 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>;
};
};
The bt-hci@0 node configures an HCI SPI slave on SPI slave
interface myspi.
The host interrupt GPIO is set to gpio1 pin 2 via irq-gpios. The
GPIO flags are just for example and may be different depending on
hardware.
