A number of patches to impove or add the implementation for the spi-imx driver related to Freescale IMX51, IMX53 and IMX6. 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 V4: * Split [PATCH v4 01] into several smaller commits * Change [PATCH v4 01] into workaround to disable DMA for transfer which len mod WML not equal 0 * Rework some patches to isolate changes in one place
Anton Bondarenko (11): spi: imx: terminate RX DMA transaction in case of TX DMA timeout spi: imx: reorder HW operations enable order to avoid possible RX data loss spi: imx: replace multiple watermarks with single for RX, TX and RXT 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 spi: imx: allow only WML aligned transfers to use DMA spi: imx: remove dead RX DMA tail handling code spi: imx: replace fixed timeout with calculated spi: imx: add support for all SPI word width for DMA
