So rather than removing its DT binding entirely, it should be moved out of staging. I'm not using the LPC32xx ADC, but the IIO driver is also out of staging, so for the same reason, it would be strange to remove the DT binding.

Sure, I don't care about binding changes. We ship the DT together with the kernel on those SPEAr600 devices, so the DT backward compatibility is totally useless for us, which allows to freely change the bindings.
