Enumeration Type Documentation

enum i2c_speed_kHz

I2C master's clock frequency definition.

Before performing transfer, users should make sure that the speed_kHz parameter is defined in mtk_i2c_controller structure and configured through mtk_mhal_i2c_init_speed().

Enumerator
I2C_SCL_50kHz	Transmit data with 50 kbps.
I2C_SCL_100kHz	Transmit data with 100 kbps.
I2C_SCL_200kHz	Transmit data with 200 kbps.
I2C_SCL_400kHz	Transmit data with 400 kbps.
I2C_SCL_1000kHz	Transmit data with 1000 kbps.

enum i2c_trans_op

I2C controller operation mode definition.

Before performing transfer, users should make sure that the i2c_trans_op parameter is defined in mtk_i2c_controller structure and configured through mtk_mhal_i2c_trigger_transfer().

Enumerator
I2C_MASTER_WR	I2C master writes data to slave.
I2C_MASTER_RD	I2C master reads data from slave.
I2C_SLAVE_RX	I2C slave receives data from master.
I2C_SLAVE_TX	I2C slave sends data to master.

enum i2c_trans_mode

Enumerator
I2C_MASTER_MODE	Set I2C controller to master role.
I2C_SLAVE_MODE	Set I2C controller to slave role.
