* | atmel_spi: Driver for the Atmel SPI controller | Hans-Christian Egtvedt | 2008-06-03 | -0/+95 |
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> |
