This patch add DT binding documentation for Exynos3250 ADC IP. Exynos3250 has
special clock ('sclk_tsadc') for ADC which provide clock to internal ADC.Cc: Rob Herring <[email protected]> Cc: Pawel Moll <[email protected]> Cc: Mark Rutland <[email protected]> Cc: Ian Campbell <[email protected]> Cc: Kumar Gala <[email protected]> Cc: Randy Dunlap <[email protected]> Cc: Kukjin Kim <[email protected]> Cc: Naveen Krishna Chatradhi <[email protected]> Cc: Tomasz Figa <[email protected]> Signed-off-by: Chanwoo Choi <[email protected]> Acked-by: Kyungmin Park <[email protected]> --- .../devicetree/bindings/arm/samsung/exynos-adc.txt | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt b/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt index 5d49f2b..7532ec3 100644 --- a/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt +++ b/Documentation/devicetree/bindings/arm/samsung/exynos-adc.txt @@ -14,6 +14,8 @@ Required properties: for exynos4412/5250 controllers.
