The SPI slave interface 8f94a1bedSSimon Glass (spi_setup_slave(), spi_xfer(), etc.) is then implemented by 9f94a1bedSSimon Glass the SPI uclass. Drivers provide methods to access the SPI 10f94a1bedSSimon Glass buses that they control. The uclass interface is defined in 11f94a1bedSSimon Glass include/spi.h. The existing spi_slave structure is attached 12f94a1bedSSimon Glass as 'parent data' to every slave on each bus. Slaves 13f94a1bedSSimon Glass typically use driver-private data instead of extending the 14f94a1bedSSimon Glass spi_slave structure. 15892cac72SSimon Glass 16e4976af8SJagan Tekiif DM_SPI 17e4976af8SJagan Teki 18e4976af8SJagan Tekiconfig CADENCE_QSPI 19e4976af8SJagan Teki bool "Cadence QSPI driver" 20e4976af8SJagan Teki help 21e4976af8SJagan Teki Enable the Cadence Quad-SPI (QSPI) driver.
