dmaengine: dma-jz4780: Don't depend on MACH_JZ4780

2018-09-11T07:29:26Z

If we make this driver depend on MACH_JZ4780, that means it can be enabled only if we're building a kernel specially crafted for a JZ4780-based board, while most GNU/Linux distributions will want one generic MIPS kernel that works on multiple boards.

dmaengine: fsl-edma: add ColdFire mcf5441x edma support

2018-09-11T06:36:39Z

This patch adds support for ColdFire mcf5441x-family edma module. The ColdFire edma module is slightly different from fsl-edma, so a new driver is added. But most of the code is common between fsl-edma and mcf-edma so it has been collected into a separate common module fsl-edma-common (patch 1/3).

dmaengine: imx-sdma: add virt-dma support

2018-07-02T12:54:47Z

The legacy sdma driver has below limitations or drawbacks: 1. Hardcode the max BDs number as "PAGE_SIZE / sizeof(*)", and alloc one page size for one channel regardless of only few BDs needed most time. But in few cases, the max PAGE_SIZE maybe not enough. 2. One SDMA channel can't stop immediatley once channel disabled which means SDMA interrupt may come in after this channel terminated.There are some patches for this corner case such as commit "2746e2c389f9", but not cover non-cyclic. The common virt-dma overcomes the above limitations. It can alloc bd dynamically and free bd once this tx transfer done. No memory wasted or maximum limititation here, only depends on how many memory can be requested from kernel. For No.2, such issue can be workaround by checking if there is available descript("sdmac->desc") now once the unwanted interrupt coming. At last the common virt-dma is easier for sdma driver maintain. Signed-off-by: Robin Gong Reviewed-by: Sascha Hauer Tested-by: Lucas Stach Signed-off-by: Vinod Koul
