We are using the spear-adc driver, which is out of staging
in ./drivers/iio/adc/spear_adc.c. 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.

Best regards,

Thomas

Except I have comments on the spear binding and it's fair game to
change it being in staging, right?

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.
