The s3c24xx is alomost same as ADCv1. But, There are a little difference as following: - ADCMUX register address - ADCDAT mask (10 bit or 12 bit ADC resolution according to SoC version) - s3c24xx/s3c64xx has not included ADC_PHY enable register Signed-off-by: Chanwoo Choi Acked-by: Arnd Bergmann Signed-off-by: Jonathan Cameron --- diff --git a/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt b/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt index d3dad46c97dd..709efaa30841 100644 --- a/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt +++ b/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt @@ -11,15 +11,25 @@ New driver handles the following Required properties: - compatible: Must be "samsung,exynos-adc-v1" - for exynos4412/5250 controllers. + for exynos4412/5250 and s5pv210 controllers.
