This patch adds dma support for Freescale MXS-based SoC i.MX23/28, including apbh-dma and apbx-dma. * apbh-dma and apbx-dma are supported in the driver as two mxs-dma instances. * apbh-dma is different between mx23 and mx28, hardware version register is used to differentiate. * mxs-dma supports pio function besides data transfer. The driver uses dma_data_direction DMA_NONE to identify the pio mode, and steals sgl and sg_len to get pio words and numbers from clients. * mxs dmaengine has some very specific features, like sense function and the special NAND support (nand_lock, nand_wait4ready). These are too specific to implemented in generic dmaengine driver. * The driver refers to imx-sdma and only a single descriptor is statically assigned to each channel.
