Match style mixing

OF match style can be combined with any other matching mechanism. In the following example, we have a mix of DT and device ID match styles:

We fill an array for the device ID match style, each device with its data:

static const struct platform_device_id sdma_devtypes[] = { 
    { 
        .name = "imx51-sdma", 
        .driver_data = (unsigned long)&sdma_imx51, 
    }, { 
        .name = "imx53-sdma", 
        .driver_data = (unsigned long)&sdma_imx53, 
    }, { 
        .name = "imx6q-sdma", 
        .driver_data = (unsigned long)&sdma_imx6q, 
    }, { 
        .name = "imx7d-sdma", 
        .driver_data = (unsigned long)&sdma_imx7d, 
    }, { 
        /* sentinel */ 
    } 
}; 
MODULE_DEVICE_TABLE(platform, sdma_devtypes); 

We do the same for OF match style:

static const struct of_device_idsdma_dt_ids[] = { { .compatible = "fsl,imx6q-sdma", ...
