Function Documentation

eth_adin2111_lock()

int eth_adin2111_lock	(	const struct device *	dev,
		k_timeout_t	timeout
	)

Locks device access.

Parameters

[in]	dev	ADIN2111 device.
	timeout	Waiting period to lock the device, or one of the special values K_NO_WAIT and K_FOREVER.

Return values

0	Device locked.
-EBUSY	Returned without waiting.
-EAGAIN	Waiting period timed out.

eth_adin2111_reg_read()

int eth_adin2111_reg_read	(	const struct device *	dev,
		const uint16_t	reg,
		uint32_t *	val
	)

Reads host MAC interface register over SPI.

Note

The caller is responsible for device lock. Shall not be called from ISR.

Parameters

[in]	dev	ADIN2111 device.
	reg	Register address.
[out]	val	Read value output.

Return values

0	Successful write.
<0	Error, a negative errno code.

eth_adin2111_reg_write()

int eth_adin2111_reg_write	(	const struct device *	dev,
		const uint16_t	reg,
		uint32_t	val
	)

Writes host MAC interface register over SPI.

Note

The caller is responsible for device lock. Shall not be called from ISR.

Parameters

[in]	dev	ADIN2111 device.
	reg	Register address.
	val	Value to write.

Return values

0	Successful write.
<0	Error, a negative errno code.

eth_adin2111_unlock()

int eth_adin2111_unlock

(

const struct device *

dev

)

Unlocks device access.

Parameters

[in]

dev

ADIN2111 device.

Return values

0	Device unlocked.
-EPERM	The current thread does not own the device lock.
-EINVAL	The device is not locked.
