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. Anton Bondarenko (8): 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 selection for iMX53 and iMX6 controller type 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 spi: imx: Add support for SPI Slave mode for imx53 and imx6 chips .../devicetree/bindings/spi/fsl-imx-cspi.txt | 3 + drivers/spi/spi-imx.c | 486 ++++++++++++++++----- 2 files changed, 388 insertions(+), 101 deletions(-) -- 2.5.2
