This patchset add 'exynos_adc_data' structure which includes some functions
to control ADC operation and specific data according to ADC version (v1 or v2).

This new structure makes a lot of sense for covering the exynos specific
versions, but it will likely give a little more complexity for the
older models. We'll have to deal with that later then, no need to
hold up your patch. Interestingly, the version numbers seem weird. The
old driver uses

        {
                .name           = "s3c24xx-adc",
                .driver_data    = TYPE_ADCV1,
        }, {
                .name           = "s3c2443-adc",
                .driver_data    = TYPE_ADCV11,
        }, {
                .name           = "s3c2416-adc",
                .driver_data    = TYPE_ADCV12,
        }, {
                .name           = "s3c64xx-adc",
                .driver_data    = TYPE_ADCV2,
        }, {
                .name           = "samsung-adc-v3",
                .driver_data    = TYPE_ADCV3,
        }

Where TYPE_ADCV3 seems to be the same as the new ADC_V1 used in this
driver. Do you have an explanation for that?

As per suggestion from Doug Anderson,
I've implemented IIO based ADC driver to work with Exynos5250.
keeping the plat-samsung/adc.c unchanged.

Assuming Exynos5250 is the one using the driver for the first time.
i've named it v1 and so on.

Now, This seems to cause a lot of confusion.
