Function Documentation

max149x6_reg_read()

int max149x6_reg_read	(	struct max149x6_desc *	desc,
		uint32_t	addr,
		uint32_t *	val )

Read the value of a device register.

Parameters

desc	- device descriptor for the MAX149X6
addr	- address of the register
val	- value of the register

Returns

0 in case of success, negative error code otherwise

max149x6_reg_update()

int max149x6_reg_update	(	struct max149x6_desc *	desc,
		uint32_t	addr,
		uint32_t	mask,
		uint32_t	val )

Update the value of a device register (read/write sequence).

Parameters

desc	- device descriptor for the MAX149X6
addr	- address of the register
mask	- bit mask of the field to be updated
val	- value of the masked field. Should be bit shifted by using no_os_field_prep(mask, val)

Returns

0 in case of success, negative error code otherwise

max149x6_reg_write()

int max149x6_reg_write	(	struct max149x6_desc *	desc,
		uint32_t	addr,
		uint32_t	val )

Write the value of a device register.

Parameters

desc	- device descriptor for the MAX149X6
addr	- address of the register
val	- value of the register

Returns

0 in case of success, negative error code otherwise
