The bool would be indeed nicer and still you could hard-code the desired value on DT system: + /* by default, set irq clear method on write */ + pdata->irq_clear_method = CLR_ON_WRITE; However the question is how this would influence existing platforms using board files. Are there any in kernel or in downstream?
