zephyr,bt-hci-spi-slave (on spi bus)¶

Vendor: Zephyr-specific binding

Description¶

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.

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`irq-gpios`	`phandle-array`	This property is required.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “zephyr,bt-hci-spi-slave” compatible.

Name	Type	Details
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`wakeup-source`	`boolean`	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.
