Subject: [PATCH v4 0/3] iio: adc: vf610: respect ADC clocking limitations

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.

The clock limitations are specified using the device tree, hence
I seek an Ack from the device tree maintainers here...

Changes since v3:
- Move device tree bindings to driver changes

Changes since v2:
- Add sysfs ABI documentation
- Fix commit message spelling errors

Changes since v1:
- Use ext_info for conversion mode


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
