Function Documentation

axp_get_vol()

int axp_get_vol	(	sunxi_i2c_t *	i2c_dev,
		char *	name,
		axp_contrl_info *	axp_ctrl_tbl,
		uint8_t	axp_ctrl_tbl_size,
		uint8_t	axp_addr
	)

Get the voltage value for a specific power domain controlled by AXP.

Parameters

i2c_dev	Pointer to the I2C device structure.
name	Name of the power domain.
axp_ctrl_tbl	Pointer to the AXP control information table.
axp_ctrl_tbl_size	Size of the AXP control information table.
axp_addr	AXP device address.

Returns

The voltage value of the specified power domain.

axp_set_vol()

int axp_set_vol	(	sunxi_i2c_t *	i2c_dev,
		char *	name,
		int	set_vol,
		int	onoff,
		axp_contrl_info *	axp_ctrl_tbl,
		uint8_t	axp_ctrl_tbl_size,
		uint8_t	axp_addr
	)

Set the voltage for a specific power domain controlled by AXP.

Parameters

i2c_dev	Pointer to the I2C device structure.
name	Name of the power domain.
set_vol	Voltage value to set.
onoff	Whether to turn on or off the power domain (1 for on, 0 for off).

get_ctrl_info_from_tbl()

static axp_contrl_info * get_ctrl_info_from_tbl ( char *  name, axp_contrl_info *  axp_ctrl_tbl, uint8_t  axp_ctrl_tbl_size  )

static

Get control information from the table based on the given name.

Parameters

name	The name of the control information to retrieve.

Returns

A pointer to the axp_contrl_info structure corresponding to the given name, or NULL if the name is not found in the table.
