MODULE_DEVICE_TABLE type=of means?

[Muni Sekhar]

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");
