Respect ADC clocking limitations which lead to bogous reading on
500MHz clocked Vybrid SoC's. Additionally, also implement a
sysfs-property to configure the conversion mode available in this
ADC peripherial.

Stefan Agner (3):
  iio: adc: vf610: use ADC clock within specification
  iio: adc: vf610: implement configurable conversion modes
  ARM: dts: add property for maximum ADC clock frequencies
