mspi_config()

int mspi_config

(

const struct mspi_dt_spec *

spec

)

#include <include/zephyr/drivers/mspi.h>

Configure a MSPI controller.

This routine provides a generic interface to override MSPI controller capabilities.

In the controller driver, one may implement this API to initialize or re-initialize their controller hardware. Additional SoC platform specific settings that are not in struct mspi_cfg may be added to one's own binding(xxx,mspi-controller.yaml) so that one may derive the settings from DTS and configure it in this API. In general, these settings should not change during run-time. The bindings for

See also

mspi_cfg can be found in mspi-controller.yaml.

Parameters

spec	Pointer to MSPI DT information.

Return values

0	If successful.
-EIO	General input / output error, failed to configure device.
-EINVAL	invalid capabilities, failed to configure device.
-ENOTSUP	capability not supported by MSPI peripheral.

mspi_dev_config()

int mspi_dev_config	(	const struct device *	controller,
		const struct mspi_dev_id *	dev_id,
		const enum mspi_dev_cfg_mask	param_mask,
		const struct mspi_dev_cfg *	cfg
	)

#include <include/zephyr/drivers/mspi.h>

Configure a MSPI controller with device specific parameters.

This routine provides a generic interface to override MSPI controller device specific settings that should be derived from device datasheets.

With

mspi_dev_id defined as the device index and CE GPIO from device tree, the API supports multiple devices on the same controller instance. It is up to the controller driver implementation whether to support device switching either by software or by hardware or not at all. If by software, the switching should be done in this API's implementation. The implementation may also support individual parameter configurations specified by

mspi_dev_cfg_mask. The Settings within

mspi_dev_cfg don't typically change once the mode of operation is determined after the device initialization. The bindings for

mspi_dev_cfg can be found in mspi-device.yaml.

Parameters

controller	Pointer to the device structure for the driver instance.
dev_id	Pointer to the device ID structure from a device.
param_mask	Macro definition of what to be configured in cfg.
cfg	The device runtime configuration for the MSPI controller.

Return values

0	If successful.
-EIO	General input / output error, failed to configure device.
-EINVAL	invalid capabilities, failed to configure device.
-ENOTSUP	capability not supported by MSPI peripheral.

mspi_get_channel_status()

int mspi_get_channel_status	(	const struct device *	controller,
		uint8_t	ch
	)

#include <include/zephyr/drivers/mspi.h>

Query to see if it a channel is ready.

This routine allows to check if logical channel is ready before use. Note that queries for channels not supported will always return false.

Parameters

controller	Pointer to the device structure for the driver instance.
ch	the MSPI channel for which status is to be retrieved.

Return values

0	If MSPI channel is ready.

mspi_scramble_config()

int mspi_scramble_config	(	const struct device *	controller,
		const struct mspi_dev_id *	dev_id,
		const struct mspi_scramble_cfg *	cfg
	)

#include <include/zephyr/drivers/mspi.h>

Configure a MSPI scrambling settings.

This routine provides a generic interface to to configure the scrambling feature.

Parameters

controller	Pointer to the device structure for the driver instance.
dev_id	Pointer to the device ID structure from a device.
cfg	The controller scramble configuration for MSPI.

Return values

0	If successful.
-EIO	General input / output error, failed to configure device.
-EINVAL	invalid capabilities, failed to configure device.
-ENOTSUP	capability not supported by MSPI peripheral.

mspi_timing_config()

int mspi_timing_config	(	const struct device *	controller,
		const struct mspi_dev_id *	dev_id,
		const uint32_t	param_mask,
		void *	cfg
	)

#include <include/zephyr/drivers/mspi.h>

param_mask	The macro definition of what should be configured in cfg.
cfg	The controller timing configuration for MSPI.

Return values

0	If successful.
-EIO	General input / output error, failed to configure device.
-EINVAL	invalid capabilities, failed to configure device.
-ENOTSUP	capability not supported by MSPI peripheral.

mspi_xip_config()

int mspi_xip_config	(	const struct device *	controller,
		const struct mspi_dev_id *	dev_id,
		const struct mspi_xip_cfg *	cfg
	)

#include <include/zephyr/drivers/mspi.h>

Configure a MSPI XIP settings.

This routine provides a generic interface to to configure the XIP feature.

Parameters

controller	Pointer to the device structure for the driver instance.
dev_id	Pointer to the device ID structure from a device.
cfg	The controller XIP configuration for MSPI.

Return values

0	If successful.
