A Serial Peripheral Interface (SPI) is (at least) a four-wire bus: Master Input Slave Output (MISO); Master Output Slave Input (MOSI); Serial Clock (SCK); and Chip Select (CS), which is used to connect a serial flash, AD/DA converter. The master always generates the clock. Its speed can reach up to 80 MHz, even if there is no real speed limitation (much faster than I2C as well). The Linux I2C subsystem is the interface through which the system running Linux can interact with devices connected on the system's I2C bus. It is designed in such a manner that the system running Linux is always the I2C master.
