Applied to the togreg branch of iio.git and pushed out as testing.
Whilst we are looking at this driver, Alexander, would you mind if we relaxed
the Kconfig dependencies to:
diff --git a/drivers/iio/adc/Kconfig b/drivers/iio/adc/Kconfig
index 46c4fc2fc534..fd1d68dce507 100644

Driver for the ADC module on the EP93XX series of SoC from Cirrus Logic.
It's recommended to switch on CONFIG_HIGH_RES_TIMERS option, in this
I end up doing that locally to build test patches like this one and it doesn't
seem to cause any problems.
