Hi All, I see that following dma engine driver uses MODULE_DEVICE_TABLE with ‘type=of’. What does ‘type=of’ means? 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); MODULE_AUTHOR("Xilinx, Inc."); MODULE_DESCRIPTION("Xilinx ZynqMP DMA driver"); -- Thanks, Sekhar
