gmsl_reg_read()

int32_t gmsl_reg_read	(	struct no_os_i2c_desc *	i2c_desc,
		uint16_t	reg,
		uint8_t	mask,
		uint8_t *	readval )

Read a value from a GMSL register.

Parameters

i2c_desc	- Pointer to the I2C descriptor.
reg	- Register address to read from.
mask	- Mask to apply to the read value.
readval	- Pointer to store the read value.

Returns

0 in case of success, negative error code in case of PAL errors.

		uint16_t	reg,
		uint8_t	val,
		uint8_t	mask )

Update a value in a GMSL register.

Parameters

i2c_desc	- Pointer to the I2C descriptor.
reg	- Register address to update.
val	- Value to write to the register.
mask	- Mask to apply to the value.

Returns

0 in case of success, negative error code in case of PAL errors.
