max31875_init()

int32_t max31875_init	(	struct max31875_dev **	device,
		struct max31875_init_param *	init_param
	)

Initialize the device driver befre use.

Parameters

[out]	device	- Driver handler pointer.
[in]	init_param	- Pointer to the initialization structure.

Returns

0 in case of success, error code otherwise.

max31875_reg_read()

int32_t max31875_reg_read	(	struct max31875_dev *	dev,
		uint32_t	reg,
		uint32_t *	readval
	)

Read a device register through the I2C interface.

Parameters

[in]	dev	- Driver handler pointer.
[in]	reg	- Address of the register to be read.
[out]	readval	- Pointer to the register value.

Returns

0 in case of success, error code otherwise.

Here is the caller graph for this function:

max31875_reg_write()

int32_t max31875_reg_write	(	struct max31875_dev *	dev,
		uint32_t	reg,
		uint32_t	writeval
	)

Write a device register through the I2C interface.

Parameters

[in]	dev	- Driver handler pointer.
[in]	reg	- Address of the register to be written.
[in]	writeval	- New value for the register.

Returns

0 in case of success, error code otherwise.

Here is the caller graph for this function:

max31875_reg_write_mask()

int32_t max31875_reg_write_mask	(	struct max31875_dev *	dev,
		uint32_t	reg,
		uint32_t	val,
		uint32_t	mask
	)

Read-modify-write operation on a field of a register.

Parameters

[in]	dev	- Driver handler pointer.
[in]	reg	- Address of the register.
[in]	val	- New value for the bit field.
[in]	mask	- Mask of the bit field.

Returns

0 in case of success, error code otherwise.

max31875_remove()

int32_t max31875_remove

(

struct max31875_dev *

dev

)

Parameters

[in]

dev

- Device driver handler.

Returns

0 in case of success, error code otherwise.
