I hope I can split it up, later, if needed. - not yet checkpatch clean, will clean up when all the functionality works (mostly 80 char-issues) - the clock-name for clk_get is hardcoded for now. Will be adapted to the reworked clock-framework when available. - DMA is just selectable for MX1 and untested. - If you can comment on the "XXX"-marked issue, please do - ATTENTION: The original FSL-driver has a bug regarding the polarity CPOL which got flipped. So, if you used the FSL-driver before, then the SPI_MODE of your spi_device has to be corrected. Just toggle SPI_CPOL or make SPI_MODE_0 out of SPI_MODE_2, SPI_MODE_1 out of SPI_MODE_3 or vice versa.
