I'm not sure I understand what this is for? I'd expect that the interrupt would be used if specified, though if a GPIO is specified I guess that'd override it.
It is for codec IRQ though it is called en-jd-func. rt5645 IRQ is not for JD only but also other functions (like button detection). Another thing is that a separate CPU pin is used for JD IRQ in some HW design. It means some HW design use their own JD function. That's what hp-det-gpio for.
I'm still not clear here - why is there a need for a separate flag over just specifying the additional GPIO/interrupt to use for this function?
