Hi Varka,

Thank you for the comments!

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.

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()...

Thank you,
