[v4 PATCH 06/12] spi/atmel_spi: add dmaengine support

From: Nicolas Ferre Add dmaengine support. For different SoC, the "has_dma_support" is used to select the transfer mode: dmaengine or PDC. For the dmaengine transfer mode, if it fails to config dmaengine, or if the message len less than 16 bytes, it will use the PIO transfer mode. Signed-off-b

[v4 PATCH 03/12] spi/atmel_spi: status information passed through controller data

From: Nicolas Ferre The status of transfer is stored in controller data structure so that it can be used not only by atmel_spi_msg_done() function. This will be useful for upcoming dmaengine enabled driver. Signed-off-by: Nicolas Ferre Cc: grant.lik...@secretlab.ca Cc: spi-devel-general@lists.s
