iio: adc: Document the regulator/clocks for exynos-adciio-for-3.10b
The exynos ADC won't work without a regulator called "vdd" and a clock called "adc". Document this fact in the device tree bindings. Signed-off-by: Doug Anderson <dianders@chromium.org> Reviewed-by: Naveen Krishna Chatradhi <ch.naveen@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
