* spi: Use spi_alloc_slave() in each SPI driverSimon Glass2013-03-19-3/+1
| | | | | | | | Rather than each driver having its own way to allocate a SPI slave, use the new allocation function everywhere. This will make it easier to extend the interface without breaking drivers. Signed-off-by: Simon Glass <sjg@chromium.org>

* atmel_spi: Driver for the Atmel SPI controllerHans-Christian Egtvedt2008-06-03-0/+210
This adds a driver for the SPI controller found on most AT91 and AVR32 chips, implementing the new SPI API. Changed in v4: - Update to new API - Handle zero-length transfers appropriately. The user may send a zero-length SPI transfer with SPI_XFER_END set in order to deactivate the chip select after a series of transfers with chip select active. This is useful e.g. when polling the status register of DataFlash. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
