The documentation describes the bindings for the imx25 GCQ unit which is
essentially a generic conversion queue using the imx25 ADC.

Notes:
    Changes in v6:
     - Changed bindings to use adc-refp and adc-refn. Also a bit of cleanup in the
       setup routine.
    
    Changes in v5:
     - Fixed locking
     - Removed module owner

+Optional properties for subnodes:
+ - fsl,adc-refp: specifies the positive reference input as defined in
+     <dt-bindings/iio/adc/fsl-imx25-gcq.h>
+ - fsl,adc-refn: specifies the negative reference input as defined in
+     <dt-bindings/iio/adc/fsl-imx25-gcq.h>

This header should be part of this commit.

Thanks, will fix that.

Best Regards,

Markus
