How to use Xilinx ZynqMP DMA Engine driver?

[Muni Sekhar <munisekharrms@xxxxxxxxx>]

Hi All,

I see that following dma engine driver uses MODULE_DEVICE_TABLE with ‘type=of’.
What does ‘type=of’ mean? How to trigger this driver’s probe and
remove to be called?



http://lxr.linux.no/linux+v4.8/drivers/dma/xilinx/zynqmp_dma.c



static const struct of_device_id zynqmp_dma_of_match[] = {

        { .compatible = "xlnx,zynqmp-dma-1.0", },

        {}

};

MODULE_DEVICE_TABLE(of, zynqmp_dma_of_match);



static struct platform_driver zynqmp_dma_driver = {

        .driver = {

                .name = "xilinx-zynqmp-dma",

                .of_match_table = zynqmp_dma_of_match,

        },

        .probe = zynqmp_dma_probe,

        .remove = zynqmp_dma_remove,

};



module_platform_driver(zynqmp_dma_driver);
