Detailed Description

davinci_spi_platform_data - Platform data for SPI master device on DaVinci

Version

: version of the SPI IP. Different DaVinci devices have slightly varying versions of the same IP. : number of chipselects supported by this SPI master : interrupt line used to connect the SPI IP to the ARM interrupt controller withn the SoC. Possible values are 0 and 1. : list of GPIOs which can act as chip-selects for the SPI. SPI_INTERN_CS denotes internal SPI chip-select. Not necessary to populate if all chip-selects are internal. : set this to true if the SPI controller on your chip requires a write to CSHOLD bit in between transfers (like in DM355). : DMA event queue to use if SPI_IO_TYPE_DMA is used for any device on the bus.
