The DT bindings in exynos-adc.txt applies to the ADC driver (exynos-adc.c) developed based on IIO framework. The bindings are more appropriate to be under Documentation/devicetree/bindings/iio/adc/ Signed-off-by: Naveen Krishna Chatradhi <ch.naveen@xxxxxxxxxxx> To: devicetree@xxxxxxxxxxxxxxx --- .../devicetree/bindings/arm/samsung/exynos-adc.txt | 82 -------------------- .../devicetree/bindings/iio/adc/exynos-adc.txt | 82 ++++++++++++++++++++ 2 files changed, 82 insertions(+), 82 deletions(-) delete mode 100644 Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt create mode 100644 Documentation/devicetree/bindings/iio/adc/exynos-adc.txt diff --git a/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt b/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt deleted file mode 100644 index b87749a..0000000 --- a/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt +++ /dev/null @@ -1,82 +0,0 @@ -Samsung Exynos Analog to Digital Converter bindings - -The devicetree bindings are for the new ADC driver written for -Exynos4 and upward SoCs from Samsung. - -New driver handles the following -1.
