Thank you.
Meanwhile, I tried ipipe-arm kernel with latest xenomai from git on
NanoPi-NEO. Interrupts configured from sysfs interface works, doesn't
display any message, but when requested with rtdm_irq_request

//request_irq(irq, irig_r_isr_test, 0, DRIVER_NAME, NULL); //this works
rtdm_irq_request(&irq_handle, irq, irig_r_isr_test, RTDM_IRQTYPE_EDGE,
DRIVER_NAME, NULL); //this not
irq_set_irq_type(irq, IRQF_TRIGGER_FALLING | IRQF_TRIGGER_RISING);
rtdm_irq_enable(&irq_handle);

sunxi_pinctrl_irq_handler(struct irq_desc *desc) routine never get called.
