It would also possible some of patches can be applied for other Freescale controllers using spi-imx driver but could not be tested due to lack of hardware. Changes since V3: Addressed comments from V3 review, simplified timeout calculation Anton Bondarenko (7): spi: imx: Fix DMA transfer spi: imx: replace fixed timeout with calculated one spi: imx: add support for all SPI word width for DMA transfer spi: imx: add function to check for IMX51 family controller spi: imx: Add support for loopback for ECSPI controllers spi: imx: return error from dma channel request spi: imx: defer spi initialization, if DMA engine is pending drivers/spi/spi-imx.c | 320 +++++++++++++++++++++++++++++++++++++------------- 1 file changed, 237 insertions(+), 83 deletions(-) -- 2.6.3
