OK, I'll add this patch.
But, I have a question.
Your patch add following compatible string.
"s3c64100-adc" is right?
static const struct of_device_id exynos_adc_match[] = {
{
+ .compatible = "samsung,s3c64100-adc",
+ .data = &exynos_adc_s3c64xx_data,
+ }, {

OK, I'll add it in exynos3250.dtsi as following:
adc: adc@126C0000 {
- compatible = "samsung,exynos-adc-v3";
+ compatible = "samsung,exynos3250-adc",
+ "samsung,exynos-adc-v2";
reg = <0x126C0000 0x100>, <0x10020718 0x4>;
interrupts = <0 137 0>;
- clock-names = "adc", "sclk_tsadc";
+ clock-names = "adc", "sclk";
clocks = <&cmu CLK_TSADC>, <&cmu CLK_SCLK_TSADC>;
#io-channel-cells = <1>;
io-channel-ranges;
