Detailed Description

struct s3c64xx_spi_info - SPI Controller hardware info : Bit-mask for {TX|RX}_FIFO_LVL bits in SPI_STATUS register. : Bit offset of RX_FIFO_LVL bits in SPI_STATUS regiter. : Bit offset of TX_DONE bit in SPI_STATUS regiter. : True, if the controller supports HIGH_SPEED_EN bit. : True, if the controller does not include a clock mux and prescaler unit.

The Samsung s3c64xx SPI controller are used on various Samsung SoC's but differ in some aspects such as the size of the fifo and spi bus clock setup. Such differences are specified to the driver using this structure which is provided as driver data to the driver.
