This creates a 1:1 mapping between the addresses used by tscadc and those in its child nodes (adc, tsc). Without such a mapping, the reg = ... lines in the tsc and adc nodes do not create a resource. Probing the fsl-imx25-tcq and fsl-imx25-tsadc drivers will then fail since there's no IORESOURCE_MEM.
