Hi, Lad Thanks a lot for the links and suggestions! Finally I resolved the problem with the call of platform_get_irq_byname and irq_get_trigger_type. Btw, I just have a question about the of_irq_to_resource function. At the beginning I tried to use platform_get_irq and of_irq_to_resource to get the irq name and flags information, but it seems of_irq_to_resource does not work as expected, maybe I called incorrectly somewhere, here I just want to ask, do you think that if of_irq_to_resource still could be used to get the resource with the irq returned from platform_get_irq?
