Additionally,
Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt has not included
"samsung,s3c6410-adc" compatible string. Should I add this string in exynos-adc.txt?

drivers/iio/adc/exynos-adc.c has not includeded following compatible string.
Should I add this compatible string on exynos-adc.c?

+			Must be "samsung,s3c2440-adc" for

+			Must be "samsung,s3c2440-adc" for
+				the ADC in s3c2440 and compatibles
+			Must be "samsung,s3c2443-adc" for
+				the ADC in s3c2443 and compatibles

Thanks,
