The RSB controller speaks a simplified two wire protocol at speeds up to 20MHz. It is used on sun8i and sun9i family SoCs to communicate with power management ICs. RSB isn't really I2C or SMBus, but the driver exposes an iicbus interface to simplify power management IC drivers (which may need to support both RSB and I2C connectivity). END
