2025-01-22spi: atmel: Really drop atmel_spi.hAlexander Dahl
First try dropping this was with commit 37434db29be4 ("spi: atmel: Drop atmel_spi.h") back in 2018 which was reverted not much later with commit 5270df283676 ("Revert "spi: atmel: Drop atmel_spi.h""). Second try dropping this was in 2020 with commit beeb34ac0cc6 ("spi: atmel: Drop atmel_spi.h"), but that only moved all the definitions into the source file and did not remove the header file. Currently all of the definitions in the header file are (still) contained in the source file, and the header file is include nowhere.

2018-04-07Revert "spi: atmel: Drop non-dm code"Tom Rini
As we aren't quite able to convert some platforms with a very small size limit in SPL yet, we need to revert this for now. This reverts commit 7b0947787358c6b277431d6b76ce043d8bec641d. Signed-off-by: Tom Rini <trini@konsulko.com>

2014-11-17spi, atmel: move CONFIG_SYS_SPI_WRITE_TOUT into common headerHeiko Schocher
move CONFIG_SYS_SPI_WRITE_TOUT into drivers/spi/atmel_spi.h and define a default value. Delete this define in the board config files, where it is possible (all boards use currently the same value).

2008-06-03atmel_spi: Driver for the Atmel SPI controllerHans-Christian Egtvedt
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>
