| 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. |
| |
| compatible: "zephyr,bt-hci-spi-slave" |
| |
| include: base.yaml |
| |
| on-bus: spi |
| |
| properties: |
| irq-gpios: |
| type: phandle-array |
| required: true |
