where are you using fsl_asrc_devtype,,,?

I got your point. I will drop all these and move ids behind probe/remove() as you suggested at the first place and then use of_device_is_compatible() inside the probe() instead.

devm_regmap_init_mmio_clk(&pdev->dev,

I'll refine to

devm_regmap_init_mmio_clk(&pdev->dev, "mem", regs,

                            &fsl_asrc_regmap_config);

Sorry I don't see any problem with this devm_request_irq()...
